I hear a lot about Wesley's WW cleaner but I've been using Simple Green for a while and it does a great job as long as you clean the WWW often. The little narrow WW tires on my Ultra Classic is so small, it just as well could have been a Blackwall tire.

 

That's what I always did.

 

Wesley's is pretty harsh on white walls, leaves a lot of cracking and pitting.

Try, soap and water when you wash you bike, then use the magic Erasers and wipe dry with clean micro fiber towel.

Mine stay "new" this way.

 

WD-40 works great, & not it does not make your tires slick.

 

Paint thinner, works like magic..

 

Cycle Care wheel cleaner and a brass brush

 

No one's mentioned a motorcycle jack...essential - it cuts your time in half when washing the WWW's.

 

Mean Green and minimal elbow grease.

 

I found out today (by mistake, grabbed the wrong spray bottle) that TILEX with soap scum remover works like a charm! Man my wide white walls were dirtier than the floor at the local Wal-Mart. Sprayed the whitewalls getting ready to wash the bike, and the dirt and crud just started sliding off. Really didn't even have to scrub!

 

Bleche-white and steel wool. Let the cleaner sit for a few minutes to give it time to break down the oils.
