Bed bugs

Has anyone in Cyprus had to deal with bed bugs at home? I’m curious how bad the infestation was, whether you managed to get rid of them completely, or if you just ended up living with them and keeping them under control. I’d really like to hear your experience and what worked for you.

Koch Chemie products question

Hello everyone,

I’m looking into buying some Koch Chemie products, and I noticed that they list the pH value of each product on the bottle.

This got me thinking: many detailers recommend using pH-neutral or pH-balanced products on vehicle paint. However, I noticed that some of Koch Chemie’s spray waxes and sealants have an acidic pH, around 4.5.

How can an acidic product be safe for automotive paint? Is there something I’m missing about how pH affects paint and protective products? Since Koch Chemie is highly recommended by many detailers, I’d be interested in understanding the chemistry behind it.

Thanks in advance for any insights!
