A good Rim Cleaner

[Perfectlap]

the best I have used is the Poorboys wheel cleaner, very potent. Needs to be diluted then rinsed off. Gets the barrell of the wheel effortlessly.
Don't spend to much time coating the wheels because they need to stripped regularly to break loose the brake dust, tar and sediments.

After each washing (some use Dawn, also effective) give it a quick polish with a top shelf product like Klasse All In One, Werkstatt Prime or Zaino Z2.
This is very important.
To make wipe downs quick and easy I swear by FK 425 for its anti-statics. Just using a polish will make the wipe down quick but the anti-static uses rainfall to let the soot and debris wash away.

I've tried P21S and the over the counter stuff but its pricey and less potent.
a good idea is to use one color towel for use only on wheels. I'm not convinced that brake dust ever really fulls comes out of the towel.
