Citric acid, IPA, caustic soda, limonene, etc.
I tend to get from either Amazon or https://mistralni.co.uk/ I could check when I get home where the oxalic acid came from as I have a feeling it wasn't either of the above.
Supermarket formulations are generally overpriced and often contain not much of chemical you're after.

In what quantities are you buying?
-Kilo of citric acid is easiest from a Turkish wholesaler or larger shop as lemon salt.
-caustic soda is available in 5l containers from a cash and carryIPA seems to be difficult in larger quantities, usually from electrical supplies places that sell boards but you can get away with rubbing alcohol from places like PAK hair products. Also a good source for 1l and 5l of peroxide cream.
I want to buy chemicals, mainly for cleaning stuff. Citric acid, IPA, caustic soda, limonene, etc.
Can anyone recommend some kind of chemical supply company that will sell to individuals, or shall I just pick some random site on Google? Or do I just have to live with basic bitch repackaged supermarket versions?
Are supermarket versions of these things more expensive or cheaper than proper chemical supply stuff? I presume the former but I don't know
