How do I get this black stuff off? (Pro Tour)
Hoping someone has tips, driving me crazy! I know the orange staining is from my electrolytes and I’m accepting it even though it annoys me, but I can’t get the black stuff off of this part (and some faint grey stuff off the rubber seal)
I completely dissemble it and clean it, by hand and in dishwasher, fairly often too. I have ME/CFS so I don’t manage as often as I’d like but at least once a month
I’ve tried running it through a Zima dental pod cleaner with one of the tablets, hand washing, and dishwasher, but no luck yet
