e88 Wheel cleaner
 

I have yet to need to use anything more than car wash soap and water on my e88's but bought some of this to try and thought I'd see if anyone else has feedback on results:

Before installing the new wheels last year, I put a couple coats of the Armor all wheel protectant spray on and it seems to have worked pretty well for a few washes.

It says "Strong yet gentle cleaning comes from the use of pH balanced soaps" - but it does not say that the mixture itself it PH Neutral. DO NOT under any circumstances use wheel cleaners that are acidic or basic, you want something PH neutral so that you're not corroding the clear coat on the wheels.

I personally use Gyeon Iron - http://www.esotericcarcare.com/gyeon-q2m-iron/
Sonax is probably more familiar to you but works just the same - http://www.esotericcarcare.com/sonax...r-full-effect/

Having been around wheels for a long time and having washed wheels for a long period of time, you'll be best with either of those two wheel cleaners I listed.

Thanks a bunch, I'll use it on the old BMW

My pleasure! Don't thank me though, thank Esoteric for their expertise with these products and their awesome how-to videos on Youtube (https://www.youtube.com/user/EsotericAutoDetail/videos). Ceramic coated my car without any training, just watched their videos and talked with them, so big Kudos to those guys for helping the community out with these videos.

As for the silver outer rims on BBS e88, am I correct that these are bare polished aluminum and something like Mothers aluminum polish would be ok to use?

It's sunny for a few days and I dug out my car with these wheels on it and thought I'd see if anybody uses Mothers on the outer rims of their e88's ?
Only been waiting a year for this answer, haha
