After noticing some corrosion of the lugnuts on my C2S (5 months old), I spoke with a few dealers one of whom blamed it on certain detergents. They recommended using a pH neutral soap such as dishwashing soap. Has anyone else had this happen? Any tips on preventing or correcting the problem? Would this be covered under warranty. Any thoughts on this would be appreciated.

 

Do NOT use dishwashing soap. Use PS212 or whatever it is. Great wheel cleaner. Apply on cold wheels, rinse off with hose. No scrubbing. Excellent results.

 

Ditto on not using dishwashing soap & using P21S wheel cleaner instead.

Thanks for the suggestions.

 

I use Zymol wheel cleaner and after two years there are no spots what so ever. Use a brush and then hose off.....GR

 

mix a 50/50 solution of Simple Green and water.. squirt on.. soft brush, sponge or cloth to clean.. then hose off.

Make sure wheels are cold and there will not be any issue.

 

If you're particular about how glossy the clearcoat is on your wheels, do not use a brush, no matter how soft it may be. If you don't particularly care, then go ahead and use a brush.

The clearcoat on your wheels is no different from the clearcoat on your paint finish, and I would never use a brush on my paint finish. Porsche clearcoat is really soft and will scratch easily. Most people won't notice the gradual dulling over time of their wheels' high gloss shine from using a brush, and if a little loss in gloss doesn't bother you then by all means go ahead and use your brush.

But if you're really **** about maintaining that off-the-showroom look on your wheels, use a soft open cell sponge for all your wheel cleaning. And polish them occasionally, maybe once a year to maintain that high gloss you and those like you enjoy seeing on your cars.

 

I use this wool brush when the wheels are on the car:


and this boar hair brush when they are off the car:

 

I use Griot's wheel cleaner and a boar's hair brush. No problems.

 

I use a washcloth. After years of all kinds of brushes on all kinds of cars/wheels, I've found an old washcloth seems to work best - with my fingers providing the access into the lug tunnels and nooks and crannies. I wash with a bucket of warm water and maybe a 1/4 capful of good car wash stuff, and I rinse the washcloth in the hose almost back to white before it goes back in the soapy water - keeping that water clean.

Twice a year the wheels come off (winter/spring change-over), and I wash with the dreaded dawn, dry them and then use Klasse AOI followed by Klasse sealant glaze. Those polymer "waxes" can withstand the heat that wheels build up, but a regular wax will just turn to liquid and flow off. Its the polymer sealants that makes it easy to keep them clean the rest of the season, so if you don't want to use Klasse, or Zaino, try any of the polymers at the auto parts store made for clear coat paints.

Even with a sealant on the wheels, they need to be cleaned once a week (at least) or the brake dust will eat into the sealant and then the clearcoat and then the finish paint.

 

I have the problem solved. Take the wheels off and thoroughly clean them with a gentle (P-21S conditioning shampoo) cleaner. Dry them and wax them front and back, including in the lugbolt openings. Degrease your lugs thoroughly, when you think they are clean run them through the dishwasher. That will insure they are grease free. Purchase some hi-temp silver paint from an auto supply store. Spray the bolt heads with several light coats of paint. Let the paint dry/cure for several days. Then re-install the wheels with the newly shiny silver lug bolts. I cut a piece of panty hose and put it in the socket so I didn't mar the paint when I tightened the lug bolts. They came out perfectly. Now they match the wheels. If you do this a couple times a year, the wax part, not the paint part, your wheels won't be hard to clean at all.

Regarding cleaning the lugbolt openings, get a round detailing brush (like a big round pastry brush) with very soft bristles. Dip it in the clean wash water and swirl it in the openings. It works perfectly. No harm to the wheel or the finish on the lug bolts.

 

This is the best stuff I've used.....spray on, rinse off and you're done!

I've been using the P21S Wheel Gel for years. I buy the 5 liter/gallon jug, and use it on all cars in the driveway. Works like a charm.

And the Rejex is an added bene: with Rejex on the wheels to start with, most of the crud washes off on the initial rinse anyway.

 

+1 - P21S gel.

 

I never use wheel cleaner on the P-Car wheels...just hose them off and hand wash using Zaino car wash soap and a terry cloth rag...wheels cleaned at least once a week. Biggest concern using wheel cleaner, which I routinely used on my other vehicles, is dulling the finish on the big reds.
