so i've bought picrel to clean some indoor AC units of some people i know (maybe start a business later)
need some /diy/ recepe for making the cleaning and washing agents since i don't have a company and there's no way to buy commercial cleaners in my third world shithole (also nothing on the local internets)
i'm thinking about these
>wather+vinegar
>water+soap
>ethanol+PETROL+water
>water+salt+dishwashing liquid
i'm planning to buy one more pic related for deactivating/cleaning off the first cleaning agent
also internet says that both acid and alkali can damage aluminium fins on the AC unit so that's why i'm asking you guys to help an anon out if you have some experience and knowledge
