I recently found that TPTB seem to be reducing acetone availability. Our local Superdrug will now only sell me a single pathetically-small bottle, which is next to useless for most household cleaning tasks where only acetone will do.
It's this kind of nanny stateism that makes one search for what kind of dodgy purposes the substance can also be used for - making various explosives or chloroform it seems.
However totally by chance I discovered that Screwfix "No Nonsense Foam Gun Cleaner" in a big old 500ml aerosol is almost completely acetone, so good enough for me, and I now have a relatively bulk supply easily available with no pointless questioning.
Stock up now!!!
