In need of a small quantity of acetone for cleaning.

Hopefully 1 litre or so of very basic or rough grade - not for direct
human contact - should see the job done. Nothing whatever to do with
hair or nail extensions!

I have never bought it before. It's on ebay but where should I expect
to buy it in a town - high street, industrial cleaning agent
suppliers, car parts factors or..?

Any brand name to look for?

TIA
