Friend of mine says Carb Cleaner is the nuts for cleaning whitewalls.....He greening me or does it work? ( without hurtin the tires)

 

Never heard of that. I use S.O.S., Soft Scrub or Whestlys bleach white and it works fine for me.

 

Thought I smelled a Rat

 

The Westley's Bleche-White is fantastic but may bleach your tires as well -- turning them gray over time. But that's after many uses and based off of auto tires, a lot more visible than bike tires. A general all purpose cleaner and a stiff brush can do the trick as well.
