Without Daz?
Why the heck not, its for making whites white again!!!
Honestly!
I acetone my wheels + tyres after cutting the insert out of them, leave to soak 24hrs or longer (usually 2-3 months til I need to do a load more LOL), then take out of acetone, remove rubber, scrub with a cloth and they are cleaner - but slightly yellow.
Next, boil the kettle and fill up the sink - usually two full kettle full does it for me. Chuck in some Daz, or whatever else (Surf, Percil, Bold etc) and then chuck the wheels in. Leave to soak til the water cools to tepid, and then scrub each wheel up with an old toothbush (or someone elses). once all wheels done, drain the sink, then rinse each wheel under running tap and then dry.
Hey presto, wheels look like new, even the scratched ones. Woody was the one who showed me this tip.
I also know of someone (F1) who uses the dishwasher... and I don't mean his mrs'.
