Cleaning brown stains on white wall tires

[paults1]

Brown spots & stains on new white wall tires are caused by the "Antioznant" that is added to the rubber compound to help extend the life of the tire. Somehow the Antioznant leaks or gets on the white wall. I have tried many tire cleaners & chemicals using fine sand paper, brass brush, etc.  Today I used Mineral Spirits that actually removed these spots & stains. I am sure the stains will return in this hot weather we have in Florida.

I have used Black Magic's "Bleche-Wite" tire cleaner and a tire brush that cleans white walls and black walls very good.

One of the best  products is   Prepsol or  Degreaser used just before
painters use on cars before the paint is applied,
Obtained from any auto paint supplyer.
Use clean white cotton towl rags, use plenty of prepsol and keep turning rags over, and rub hard,
this is also safe on tires as it non petroleum. and will also turn your old white walls
that have gone yellow back to white.

I clean mine with an everyday kitchen degreaser from the supermarket, fairly fine steel wool and elbow grease.

Not sure if this will work but I have had amazing results with a product called Totally Awesome. Inexpensive and have had very good results in cleaning hard to remove stains so worth a try.

I always use one way to wash the rubber. Buy regular glycerin at the pharmacy, mix 100 grams of glycerin with 100 grams of water, then apply a sponge to the rubber. Do not spare the water. Otherwise, dust will stick to the tires. You can also try to cover the tires with silicone oil, which will save them in the cold and protect them from cracks and sunlight aging tires.  However, when I don't have time for deep cleaning the car, I turn to sparklewash.com. I advise you to contact specialists so as not to waste time. Without the availability of specialized equipment, it isn't easy to achieve the desired result.

To answer the first post, rubber, like plastic is surprisingly porous. So yes this additive seeps through the WW. Ever seen rubber parts with this additive that have been stored in a plastic bag for a long time? Bag turns brown and the same process on the WW. All tires and WWs are not created equal. Some will resist this staining and others won't. I have read about diamondback's process where they add a WW to a black tire. They claim to use a barrier (butyl?) between the tire rubber and the WW. Butyl is known as the best water and air tight rubber material and therefore will resist the brown creep better.

I have diamondback WWs that are on Vredestein tires. I only have to clean them once a year if that. And these are the fat Ponton width. Yes, the barrier works.

I should probably clarify a couple of things. My Ponton with the Diamondbacks has all drums so I do not have the brake dust that my W111 or the W113s have. Because of that, the brake dust issue is not nearly as bad. Second, I do clean the WW more often than once a year, but with simple green and sponges. That is just to get brake dust and dirt off. The infamous yellow stain doesn't really start showing up until months after the last cleaning. For that I use WW tire wipes another tire cleaner and looks pretty darn white. Not much effort.

I have Hankook WWs on my W111 and is a constant battle to keep the yellow creep at bay. They never have or will be as white as the Diamondback installed WW. But then again, the Hankooks are an inexpensive tire.
