isn't there a chemicals supply close to you?
i always tried to get chemicals like you say, some household product at
supermarkets.
but then i discovered a cemicals shop which i can reach easily where
everything is stocked, the assistants
know what they are doing and can help you. And the price is much lower than
substitute products.
If you add that at the professional shop you get the pure chemical with
nothing added in best concentration
i see no reason why i should not go there.
even with buying H2o2 there were no questions at all (somebody here said
the police will get you outside
the shop because h2o2 is used for illegal drug procuction.).
i remember a friend buying KNO3 (he made model rockets) which is obviously
only used for, lets say, very fast
combustible materials (or keeping flesh red at the butcher) and they did
not ask anything.
i think there was mentioned often there is some houshold cleaner which is
potassium hydroxide but i don't remember how it is called.
go to k-mart and look in the cleaners section for a powder/granulate, they
should label on the outside what it is.
but only if you can't find no chemicals supply.
