If you are going to use acetone/nail varnish remover the best type of nail varnish remover to use is the really cheap stuff i pay 50 pence per haf litre on my local market. tip into the bottom of an air tight container put tyres into it above the liquid i stand mine on a piece of an old cooling tray then put lid on and leave for at least 2 days. my tyres then come straight off,remove any residue off the rims straight away with a damp cloth
hope this is of some good to you.
