Bought a set of Michelin raised white racing letters for my Z07. Installed the letters, they looked fantastic. Did a Roll Racing event, about 10-12 runs over a 6 hour period...a few days later noticed the letters were starting to turn brown on some edges and corners and continued to get worse. Called the seller and they said to use Acetone, which I did and it worked kind of OK, at least got them about 95% back again, however went to Carlisle this past weekend (2 hours each way) and a few days after my return, all the brown spots are returning.

A sales person at an auto parts store said it is due to the tires heating up and releasing chemicals into the letters causing them to brown, and once it starts it will not stop(?). Has anyone had a similar experience and do you know how to clean them... the Acetone takes about 45 minutes a tire and not 100% effective. Help!

No experience with the product you have but "back in the day" I used to use Westly's Bleach White to clean my white walls.

What you're discribing sounds brake dust building up on the tire. A good stiff wheel brush and APC (all purpose cleaner) should do wonders.

You could also try the Adams solution

Thanks, but it is not brake dust, I have CC rotors and they don't generate any substantial brake dust.

Black Magic "Bleche-White", formerly made by Westley's, is what I have used on white lettered tires and whitewalls. Spray it on, let is sit a minute and scrub them with a soapy Brillo pad and rinse with a sponge. Works great. Sounds like you may have some gases/chemicals bleeding out from the rubber. It may subside in time. 303 Aerospace Protectant works well to give the tires a nice matte finish and protects the rubber.

I have BFG's on my C3 that I use sand paper on a sanding block. They return to yellow in a day or two.

It 's a long time I didn't clean white letters or white wall tires, I use to spray water on the tires, trow some ajax powder cleaner or other brand and rub with a small brush. Takes about 1 minute per tire and give super good result without damaging anything. Just make sure you dont rub the wheels.

Thanks, that is really old school, I remember my dad teaching me that 50 years ago, I forgot all about that...can you still buy the Ajax powder?

Too-Fast

Thanks, I used steel wool and it did nothing, I will try the sandpaper.

SOS pads always worked for me.

Didn't say it was brake dust; said what you're discribing sounded like that was what it was. Regardless, stiff brush and the cleaners mentioned should still do wonders. Also Adam talks about something the tires are doing. Take a listen and watch. Can't hurt since it doesn't seem like you're having much success with anything else.

Thanks, going to try some of the methods/products mentioned here and will report back.

I sure you can get some, or other brand.

Had the same problem with BF Goodrich tires on my 68 Chevelle. Called the factory asked what it was they said it was chemicals coming from inside the rubber. I tried everything also to clean them, even lacquer thinner. My best cleaner I used was Bleach white with a stiff brush, good luck.
