The brushes would be stuck to you if it wasn’t for meths.
Methylated spirit is alchohol which had a purple dye added which made it taste awful so people wouldn’t drink the stuff.
This didn’t work and the dye and the methanol just caused renal failure and blindness in alcoholics stupid enough to drink it.
