Cleaning tubs

fc9k I'd go easy with the acetone suggestion - acetone tends to eat through a lot of plastics and rubbers like nobodys business. Its fine for cleaning metal, but for tyres I'd stick to lighter fluid / rubbing alcohol.

I melted a blender in the lab last week. It was stuck to my hand and I had to pry it off. Things like polypropylene, polythene are ok. Perspex and acrylic not so ok. The lighter fluid will be hard to evaporate so if there's just a rim, no plastic parts at all, I'd use some acetone but if not use the lighter fluid.
