Sonax wheel cleaner is extremely effective at removing built-up brake dust and grime from wheels. A very good deal (Especially if Autobacs/Giant have sales that essentially bring the price down to 2 for 1)

What I like
Turns reddish-purple upon contact with brake-dust
Cleans effectively

What I do not like
Price
Still needs some agitation

I installed this on

This cleaner gets its job done really well! It had been a really long time since I intensively scrubbed my ride, but this Sonax Xtreme Wheel Cleaner Plus helped lighten the work that needs to be done. It took a little bit of scrubbing with a brush for some of the more stubborn and stuck on buildup, but nothing too crazy. All the years-of-accumulated brake dust were removed with minimal effort. I am sure that if we had been using this product all along we would never needed to scrub at all. It was great to see the break dust melting away. I would definitely purchase this product again once this bottle finishes! Awesome, tough performing wheel cleaner!

What I like
Strong solutions that get rid of stubborn and stuck on stains easily.

What I do not like
The price of 1 bottle of this wouldn't attract any normal customer that doesn't know of its power. Expensive!

Review
The most effective universal rim cleaner I have ever come across compared to other brands. Just spray, leave for 2-3 minutes and watch the "bleeding" purplish effect and jet-off thereafter, all the cakes of brake dust just disappears leaving your rims as good as new! The best thing is, it doesn't eat into your rims!

What I like
Easy to use, doesn't eat into rims, works for matte/chrome/alloy rims.

What I do not like
A slight bleach-like smell from the product when you spray on, small issue, but other than that it is simply brilliant!
