MEK is very difficult to get hold of now, I believe a component of it has been banned, having said that break cleaner, in the UK sold in 5 litre tins by Swarfega, Comma etc seems to smell the same, is a brilliant cleaner that evaporates quickly. I have not tried it on the solvents in question though. It also retails for about £10 a tin, great value, wouldn't be without it.
