Going to buy P21S Wheel Gel for the first time...

Mark, I am looking forward to hearing how you like the P21S. I never got around to trying the P21 wheel cleaning products either. I'd like to know if the P21S gets the stubborn little dots of tar and brake dust off the rims without resorting to clay. I plan to send my cross spoke rims in for repainting over the coming months and need to find something safe and effective.

Finally finished up the CG Diablo (Neutral pH) which never impressed me with bimmer dust. OPC was just as good or better than the Diablo in my hands.

I want to find a wheel cleaner that works without much aggitation as my Daytona wheel brushes are too thick in diameter for the new 528i rims. I need something long and flat. Just broke down and bought Sonax and Iron X to try, although I worry about doing damage to the rim, caliper and rotors. I didn't even think about P21S for some reason.

Did you ever try Brown Royal. Old Tiger seems to be a fan.

I am quite surprised to note youve never tried P21S, especially since most consider it the "king of the mountain" and measure anything/everything against it.

You make some good points here, Bob. I NEVER cheap out on products if I feel they're needed. I want a pH-neutral wheel cleaner that I can use and not have to worry about following the instructions to a T, or, if the cleaners might be perfectly fine for the wheels, but not the brakes.

I've tried Sonax. Although it's effective, I DO NOT like how it does not foam. Makes me feel like it dries up too fast.

I've tried GG HD cleaner as well. It's nice, foams a lot, but doesn't have the potency as Sonax. However, along with the other "iron dissolving cleaners", they attack the rotors pretty good, and always seem to leave rust drop stains on the barrels, even after rinsing very well. This bugs me. I do not seem to get this with non iron dissolving wheel cleaners.

I'm going to try P21S. I might like it, I might not.

Mark, the best part about P21S in my eyes is that you can let it sit on the wheels as long as you want with no adverse side effects. I haveeven sprayed it on wheels, then done the engie bay or interior part of my detail, then come back to clean thw wheels. It's good stuff, but it is a bit pricey. I'm looking forward to hearing what you think of it!
 
Mark I am looking forward to your review of the P21s. With the cost of the Sonax being so high this is definitely worth trying.
 
Good tip on the S100 may need to try that. I use P21S when I use a wheel cleaner on my cars becasue it is safe. I ruined an old Fuchs wheel years ago and learned my lesson on a 914 I was trying to resurrect and make some money on,that did not work out so well :cry:
 
Hi Mark,

What's the word on the P21S? I have Sonax coming and will order some Brown Royal after that. Still want that safe, effective cleaner so I can be one and done.

To go with the wheel cleaner, I need an ~ 10-12" long brush that is only about 1" in diameter to clean my new BMW's rims. I can't get between the barrel and the dust guard which is only a 1" gap. Maybe some type of sheepskin brush that can fit?

I love P21S! It clings, foams when agitated, and cleanes excellent! Sonax cleans excellent too, I just don't like how it doesn't foam. That makes me feel like I don't have a lot of working time.

I'm not too sure what brush you could go with for the bimmer as I've never really needed on that size.
 
P21S wheel gel is good stuff. I've let it dwell for a couple hours before on some nasty BMW rims with no adverse affects. Also, I dilute it at 3:1 for cars that have clean rims.

Kurt, I know of the perfect brush for you. Raceglaze makes a wheel brush that is long, thin, and flat. I have one and it's great. It's soft and it can get into tight spaces that other brushes can't.
 
I dont get the fuss on wheel cleaners. After you wash them and seal them all you need is soap and water and they become spotless. Ive always used Eagle One A2Z and its never failed and over the counter.
