u/IavenderSyndrome

My post about HOCI just got removed without any reason given. For anyone who missed it before it disappeared, the post was about hypochlorous acid, a WHO recognised, FDA approved compound your immune system already produces naturally, documented since World War I, used in clinical wound care, food processing, and healthcare globally. A 2024 peer reviewed article in the Journal of Drugs in Dermatology confirms its applications for wound care, acne, seborrheic dermatitis, and atopic dermatitis.

A nurse in the comments confirmed she has seen it heal wounds almost too quickly to believe in clinical settings and drank some in front of a vendor at a hospital wound care event to demonstrate the non-toxicity claim.

The post explained how to make it at home for under 10p per litre from salt, water, white vinegar, and a £5 USB electrolysis dongle, replacing hundreds of pounds worth of annual household and personal care products simultaneously.

A chemical engineer engaged with the chemistry and made legitimate corrections which were incorporated into the revised version. An experienced home producer whose detailed guide significantly improved the accuracy also contributed. The post improved under scrutiny rather than collapsing under it. 942 people shared it externally in 4 hours. Nearly 110,000 people viewed it on Reddit alone before it was pulled.Then it was removed. No explanation. No rule cited. No warning.

A post about a WHO recognised, FDA approved, peer reviewed, clinically used compound, on a biohacking subreddit, removed at peak virality without explanation.

I have asked the moderators which rule it violated. I will update if I receive a response.

The information itself is already out there. 942 shares happened before the removal and no moderator decision reaches the Telegram channels, WhatsApp groups, Discord servers, and private networks those shares went to. The removal doesn't recall the information. It just makes the point of the original post more clearly than the original post did.

A post arguing that information about cheap self-sufficient alternatives to commercial products gets suppressed because there's no profit in people knowing about it. Got suppressed at peak virality on a platform with corporate advertising interests. The timing speaks for itself.

For anyone looking for the full post, message me directly and I'll send it. The more people who have this information the better. And apparently some people would prefer you didn't.

TLDR: £5 USB dongle plus salt, water, and white vinegar makes a disinfectant 100x stronger than bleach that is safe enough to drink, replaces £300-500 worth of products per year, and your immune system already makes it naturally.

Hypochlorous acid (HOCl) is what your immune system produces naturally to kill pathogens. Documented since World War I, recognised by the WHO, approved by the FDA and EPA, and significantly more effective than bleach against bacteria, viruses, and fungi including MRSA, norovirus, and C. difficile. Non-toxic, skin safe, food safe, slightly acidic rather than pH neutral, and breaks down into saline after use leaving zero harmful residue. You can make it at home for under 10p per litre.

Before anything else, important clarifications:

HOCl is NOT bleach. Bleach is sodium hypochlorite (NaOCl). The compounds are related and exist in pH dependent equilibrium but they are not the same thing. HOCl is not diluted bleach.

This process does NOT involve mixing vinegar and bleach. That generates toxic chlorine gas and must never be done. What we are doing is electrolysis of a saline solution acidified with vinegar. Completely different.

Electrolysis does liberate small amounts of hydrogen, oxygen, and chlorine gas. This is not going to blow up or poison your house. The vast majority of chlorine reacts within the solution to form HOCl. A small amount escapes creating a mild bleach smell, less than you would get from household bleach left open to the air. Most bubbles are hydrogen, the lightest element in the universe, colourless, odourless, non-toxic, rises and disperses immediately. Always work in a ventilated area and do not inhale directly over the solution during electrolysis.

What it replaces

Bleach and all chlorine cleaners

Antibacterial hand soap and sanitiser

Surface disinfectant sprays

Wound care antiseptics and pharmaceutical topical antimicrobials

Mouthwash and oral rinse

Produce wash

Pet disinfection products

Dandruff shampoo and medicated scalp treatments

Antibacterial body wash

Shoe deodorant and athlete's foot prevention

Air fresheners and fabric odour eliminators including cooking smells and pet odours

All from the same generator. Indefinitely. From salt, water, and vinegar.

Personal care applications at 100-200ppm

Body wash: apply to skin in the shower, leave 30-60 seconds contact time, rinse. Kills surface bacteria and fungi responsible for body odour, folliculitis, and skin infections without stripping your skin barrier. No synthetic fragrance, no parabens, no endocrine disrupting compounds.

Scalp and hair treatment: apply to wet scalp before shampooing, massage in, leave 1-2 minutes. Dandruff and seborrheic dermatitis are primarily caused by Malassezia, a fungal organism colonising the scalp. HOCl is genuinely antifungal against Malassezia, addressing root cause rather than masking symptoms with zinc pyrithione or ketoconazole. Also effective against scalp folliculitis. Use as a leave-on scalp spray between washes for continuous antimicrobial maintenance.

Oral rinse: dilute to 50-100ppm, swill for 30-60 seconds, spit. Kills periodontal bacteria including gram-negative anaerobes responsible for gum disease. Disrupts dental plaque biofilm more effectively than alcohol-based mouthwash because the oxidative mechanism penetrates biofilm matrix that alcohol cannot reach. Eliminates sulphur-producing bacteria causing bad breath at source. Safe to swallow at these concentrations.

Wound care: apply to cleaned wounds at 100-200ppm. More potent than raw honey on pure kill rate and significantly safer than hydrogen peroxide or iodine, both of which are cytotoxic to fibroblasts, the cells that heal wounds. Used in clinical wound care products like Vashe, confirmed by nursing professionals.

Face and acne treatment: kills Cutibacterium acnes and Staphylococcus epidermidis without antibiotic resistance risk, irritation, or dryness of conventional acne treatments. Safe for direct application to sensitive and compromised skin at 100-200ppm.

Pet care: safe if licked at use concentrations. Treats hot spots, ear infections, and skin issues without pharmaceutical intervention.

Shoe care: spray inside shoes after wearing. Eliminates odour at source and breaks the athlete's foot reinfection cycle by treating shoes alongside feet.

Surface and household applications at 200ppm

Kitchen surfaces and food prep areas, food safe, no rinse required

Bathroom disinfection

Mould treatment

Fabric freshening, sofas, chairs, pet beds

Air freshening and odour elimination via spray

Produce washing

Conservative total savings: £26-47 per month on products HOCl replaces entirely.

HOCl costs under 10p per litre to make at home. At 37ml daily use across all applications that is roughly £1.50 per month at most.

Annual saving: £290-540 per year from one £25-40 setup cost that pays for itself within the first month.

Critical laundry note: HOCl cannot simply be added to a machine wash cycle alongside detergent. Alkaline laundry detergent neutralises HOCl entirely. For laundry sanitising use HOCl as a separate soak with no other additives.

How to make it

USB electrolysis dongle, £5-8 from AliExpress or Amazon. These are marketed as sodium hypochlorite generators which is technically true, but ignore all packaging, instructions, and included measuring spoons. Electrolysis is electrolysis. The difference between making HOCl and bleach is entirely in your recipe and pH management, not the device. Must have MMO coated titanium electrodes, not plain titanium which accumulates oxide layers degrading performance over time, and never stainless steel which leaches harmful chromium into solution.

Digital pH meter, £10-15. Strongly recommended over strips as it gives significantly more reliable readings. Calibrate with buffer solution before use.

pH buffer solution, £3-5. For calibrating the meter.

Free chlorine test strips, £3-5. Range 0-300ppm. Verify concentration of every single batch before use.

Glass or food grade plastic measuring cup, not metal.

Measuring spoons and stirring spoon.

Opaque spray bottles. Light accelerates HOCl breakdown significantly. Dark HDPE or amber glass gives longest shelf life. Hairdresser-style continuous mist spray bottles work very well.

Distilled or deionised water. Tap water is unpredictable as dissolved minerals play havoc with pH management. Carplan deionised water from Halfords at £1-2 for 5L is the cheapest UK source. If your local tap water is genuinely soft and high quality it is worth trying, at worst the batch fails and you remake it at negligible cost.

USB power source. Phone charger or power bank. Must not exceed 1 amp.

Total setup cost: £25-40

Ongoing cost per litre: under 10p

The recipe per 300ml batch

300ml distilled or deionised water

1 teaspoon non-iodised kosher or sea salt, fine not rock salt, no anti-caking agents

1/4 teaspoon plain white vinegar at 5-8%. Not cider vinegar. Not vinegar with preservatives.

Critical point on vinegar: white vinegar is the only suitable readily available household acid for this process. Do not substitute citric acid. HOCl reacts with citric acid and is neutralised within minutes, dropping free chlorine to zero ppm regardless of how well the electrolysis worked. This has been confirmed by direct testing. Acetic acid in white vinegar resists HOCl's oxidative power and is the correct choice. Vinegar is not strictly necessary but adding it ensures HOCl dominance by keeping pH in the correct range and produces a higher purity result.

The process

Step 1: measure water, add salt, stir until completely dissolved.

Step 2: add vinegar and stir.

Step 3: check starting pH with digital meter, target pH 4-6, aim for pH 5.

Step 4: submerge electrolysis dongle head and plug into USB power source.

Step 5: run 10 minutes for 200ppm or 5 minutes for 100ppm.

Step 6: unplug, gently stir, remove dongle and rinse head with clean water.

Step 7: allow to settle 1 minute.

Step 8: check both pH and free chlorine with meter and strips. Target pH 5-6.5 and 100-200ppm free chlorine. If pH has risen above 6.5 add a small additional amount of vinegar and recheck.

Step 9: decant into opaque spray bottle immediately.

If readings do not match targets:

pH too high: add small amount of vinegar, stir, recheck.

pH too low: add small amount of water to dilute.

Chlorine too low: run additional 5 minute electrolysis cycles and recheck.

Chlorine zero despite correct pH: citric acid contamination or electrode issues

pH and HOCl dominance

HOCl is slightly acidic by nature, not pH neutral as sometimes stated. The pH determines the ratio of HOCl to hypochlorite ion across a gradual equilibrium curve, not a binary switch.

pH 5: over 99% HOCl

pH 6: over 90% HOCl

pH 7: around 80% HOCI

pH 7.5: approximately 50/50 split

Above pH 7.5: hypochlorite increasingly dominates

Keeping pH between 5-6.5 ensures HOCl dominance. pH 6 is a practical settled point that gives over 95% HOCl with a less strongly smelling solution than pushing to pH 5.

Concentration guide

50-100ppm: oral rinse, lip application, sensitive skin

100-200ppm: body wash, scalp, wound care, acne, facial skin

200ppm: maximum recommended for skin contact

200-500ppm: surface disinfection, produce wash, shoe treatment, laundry soak

Shelf life:

Homemade HOCl is less stable than commercially produced HOCl. Real world shelf life in opaque containers away from light and heat is 1-2 weeks. The practical approach is making fresh weekly batches rather than stockpiling. At under 10p per litre this costs almost nothing and ensures you are always using potent solution. Always retest with chlorine strips before using a stored batch. If free chlorine reads below 50ppm make a fresh batch.

*Why does nobody know about this?*

You cannot patent salt water electrolysis. There is no ongoing revenue in a product people make themselves from the most abundant materials on earth. So the entire infrastructure of commercial interest, advertising, medical education funding, retail distribution, flows toward profitable alternatives rather than the free one.

The shampoo industry sells you SLS-based products that strip your scalp barrier and trigger the Malassezia overgrowth that causes the dandruff they then sell you medicated shampoo to treat. The wound care industry sells you hydrogen peroxide and iodine that damage the tissue they are supposed to help heal. The disinfection industry sells you bleach that leaves toxic residue on the surfaces you eat from.

HOCl does all of it better. For pennies. From salt, water, and vinegar. And has done since World War I.

The knowledge is not hidden. It is just not profitable for anyone to tell you.

You can make a limitless supply of the most powerful natural disinfectant on earth from salt, water, and a £30 setup. Your white blood cells already make it.

Hypochlorous acid (HOCl) is what your immune system produces naturally to kill pathogens. It's been documented since World War I, recognised by the WHO, approved by the FDA and EPA, and is 80-200 times more effective than bleach against bacteria, viruses, and fungi including MRSA, norovirus, and C. difficile.

It's also completely non-toxic, skin safe, food safe, pH neutral, and breaks down into saline after use leaving zero harmful residue.

You can make it at home for pennies per litre from three things you already have or can get for almost nothing - salt, water, and electricity.

What it replaces:

Bleach and all chlorine cleaners

Antibacterial hand soap and sanitiser

Surface disinfectant sprays

Wound care antiseptics and pharmaceutical topical antimicrobials

Mouthwash and oral rinse

Produce wash

Pet disinfection products

Dandruff shampoo and medicated scalp treatments

Antibacterial body wash

Most commercially sold disinfection and personal care products simultaneously

All from the same generator. Indefinitely. From salt and water.

Personal care applications at 100-200ppm:

Body wash substitute

Apply to skin in the shower, leave 30-60 seconds contact time, rinse. Kills surface bacteria and fungi responsible for body odour, folliculitis, and skin infections without stripping your skin barrier like SLS-based body washes. pH neutral so it doesn't disrupt your skin's acid mantle. No synthetic fragrance, no parabens, no endocrine disrupting compounds sitting against your skin all day.

Scalp and hair treatment

Apply to wet scalp before shampooing, massage in, leave 1-2 minutes. Dandruff and seborrheic dermatitis are primarily caused by Malassezia, a fungal organism that colonises the scalp. HOCl is genuinely antifungal against Malassezia, addressing the root cause rather than just masking symptoms with zinc pyrithione or ketoconazole. Also effective against scalp folliculitis, a bacterial infection of hair follicles that most medicated shampoos don't adequately address. Use as a leave-on scalp spray between washes for continuous antimicrobial maintenance.

Oral rinse

Dilute to 50-100ppm, swill for 30-60 seconds, spit. Kills periodontal bacteria including the gram-negative anaerobes responsible for gum disease at the root cause level. Disrupts dental plaque biofilm more effectively than alcohol-based mouthwash because the oxidative mechanism penetrates biofilm matrix that alcohol can't reach. Eliminates sulphur-producing bacteria causing bad breath at source rather than masking with fragrance. Safe to swallow at these concentrations; your body produces it naturally.

Wound care

Apply to cleaned wounds at 100-200ppm. More potent than raw honey on pure kill rate, significantly safer than hydrogen peroxide or iodine which are cytotoxic to fibroblasts, the cells that heal wounds. HOCl kills pathogens without damaging the healing tissue unlike most conventional wound antiseptics. Used in clinical wound care for exactly this reason.

Lip healing

Apply 1-2 drops to damaged lips, allow to absorb, seal with lanolin. Addresses infection risk in open picked or chapped tissue without stinging, without cytotoxicity, without any concerning chemistry.

Face and skin conditions

Acne, eczema, rosacea, psoriasis - all have bacterial or fungal components that HOCl addresses directly. At 100-200ppm safe for facial skin including sensitive and compromised skin. Reduces inflammatory microbial load without the irritation of benzoyl peroxide or the hormonal concerns of steroid creams.

Pet care

Safe if licked at use concentrations. Treats hot spots, ear infections, paw conditions, and general skin issues in pets without pharmaceutical intervention.

Surface and household applications at 200-500ppm:

Kitchen surfaces and food prep areas - food safe, no rinse required

Bathroom disinfection

Mould treatment

Air purification via spray or nebuliser

Laundry sanitising - add to wash cycle

Produce washing - kills surface pathogens and pesticide residue

How to make it:

You need:

Two titanium electrodes, which cost roughly £10-20 on eBay. Must be titanium as steel and copper leach toxic metals into solution

A 9-12V DC power supply but a cheap phone charger adapter works, £5-15

A glass or food grade HDPE container

Non-iodised salt

Distilled or deionised water

pH strips or a pH meter — £3-20

Aquarium chlorine test strips to verify concentration - £3-5

Process:

Dissolve 5-10g non-iodised salt per litre of distilled water - 0.5-1% saline

Submerge titanium electrodes connected to your DC power supply

Run electrolysis for 10-30 minutes

Monitor pH throughout, keep it between 5-6.5. This is the most critical step. Use a small amount of citric acid to lower pH if it rises. Above pH 7.5 you're making sodium hypochlorite - bleach - not HOCl

Test with aquarium chlorine strips to confirm concentration - aim for 200-500ppm

Transfer to a dark HDPE bottle immediately - light degrades HOCl rapidly

Concentration guide:

50-100ppm - oral rinse, lip application, sensitive skin

100-200ppm - body wash, scalp treatment, wound care, facial skin

200-500ppm - surface disinfection, laundry, produce wash

500ppm+ - heavy duty surface disinfection only, dilute for any skin contact

Total setup cost: £30-70

Ongoing cost per litre: pennies

Shelf life: 3-6 months in a sealed dark container, longer if refrigerated

Connect a small solar panel to your DC power supply and the entire system becomes completely off-grid — unlimited antimicrobial production from sunlight and salt water indefinitely. No supply chain dependency. No ongoing product cost. Completely self sufficient.

HOCl kills pathogens without damaging the healing tissue unlike most conventional wound antiseptics. Used in clinical wound care for exactly this reason.

Lip healing

Apply 1-2 drops to damaged lips, allow to absorb, seal with lanolin. Addresses infection risk in open picked or chapped tissue without stinging, without cytotoxicity, without any concerning chemistry.

Face and skin conditions

Acne, eczema, rosacea, psoriasis - all have bacterial or fungal components that HOCl addresses directly. At 100-200ppm safe for facial skin including sensitive and compromised skin. Reduces inflammatory microbial load without the irritation of benzoyl peroxide or the hormonal concerns of steroid creams.

Pet care

Safe if licked at use concentrations. Treats hot spots, ear infections, paw conditions, and general skin issues in pets without pharmaceutical intervention.

Surface and household applications at 200-500ppm:

Kitchen surfaces and food prep areas - food safe, no rinse required

Bathroom disinfection

Mould treatment

Air purification via spray or nebuliser

Laundry sanitising - add to wash cycle

Produce washing - kills surface pathogens and pesticide residue

How to make it:

You need:

Two titanium electrodes, which cost roughly £10-20 on eBay. Must be titanium as steel and copper leach toxic metals into solution

A 9-12V DC power supply but a cheap phone charger adapter works, £5-15

A glass or food grade HDPE container

Non-iodised salt

Distilled or deionised water

pH strips or a pH meter — £3-20

Aquarium chlorine test strips to verify concentration - £3-5

Process:

Dissolve 5-10g non-iodised salt per litre of distilled water - 0.5-1% saline

Submerge titanium electrodes connected to your DC power supply

Run electrolysis for 10-30 minutes

Monitor pH throughout, keep it between 5-6.5. This is the most critical step. Use a small amount of citric acid to lower pH if it rises. Above pH 7.5 you're making sodium hypochlorite - bleach - not HOCl

Test with aquarium chlorine strips to confirm concentration - aim for 200-500ppm

Transfer to a dark HDPE bottle immediately - light degrades HOCl rapidly

Concentration guide:

50-100ppm - oral rinse, lip application, sensitive skin

100-200ppm - body wash, scalp treatment, wound care, facial skin

200-500ppm - surface disinfection, laundry, produce wash

500ppm+ - heavy duty surface disinfection only, dilute for any skin contact

Total setup cost: £30-70

Ongoing cost per litre: pennies

Shelf life: 3-6 months in a sealed dark container, longer if refrigerated

Connect a small solar panel to your DC power supply and the entire system becomes completely off-grid — unlimited antimicrobial production from sunlight and salt water indefinitely. No supply chain dependency. No ongoing product cost. Completely self sufficient.

**The obvious question — why doesn't everyone know about this?**

You can't patent salt water electrolysis. There's no ongoing revenue in a product people make themselves from the most abundant materials on earth. So the entire infrastructure of commercial interest - advertising, medical education funding, retail distribution, product development - flows toward profitable alternatives rather than the free one.

The shampoo industry sells you SLS-based products that strip your scalp barrier and trigger the Malassezia overgrowth that causes the dandruff they then sell you medicated shampoo to treat. The wound care industry sells you hydrogen peroxide and iodine that damage the tissue they're supposed to help heal. The disinfection industry sells you bleach that leaves toxic residue on the surfaces you eat from.

HOCl does all of it better. For pennies. From salt and water. And has done since World War I.

The knowledge isn't hidden. It's just not profitable for anyone to tell you.
