How do you remove the blue stain on new whitewalls?

"However, for those excited to get the pop white accent tires are known for, a quick cleaning with a soft bristled brush, some mild dish soap, hot water and some elbow grease will reveal the bright white rubber beneath"

More info re why from  TireRack at

I always used and S O S pad. They still make whitewalls?

So what vehicle do you have these whitewalls on?

"I am no more humble than my talents require." Oscar Levant (1906 - 1972)

buy a bottle of whitewall cleaner and a bristle brush and use a little elbow grease.

Warm water and a bit of soap removes the protectont layer very easily in most cases. It is a soap based coating. (sometimes wax - in which case a bit of Varsol or other solvent does the job)

Unless you got :blue-dtripe" tires - in which case they are meant to stay blue - not very common. (BF Goopdrich Bias Ply Blue-lines from the 60s come to mind)
