I have noticed that the white lettering on the handle can rub off on the wheel. I ended up scraping off the painted lettering to prevent it from getting rubbed off onto the painted wheel when cleaning the barrels.
 
If this is what you are seeing, some Revive polish by hand should easily remove the paint transfer from your wheels.

Maybe try some fishing rod grip tape to cover the handles?  That should be tacky enough when the handles are wet, but provide a cushion over the fiberglass Woolie handle.
