I used the Q Tips to remove a lot more grease (thanks for the tip, RMR) and also cleaned the wheels! Got this cleaner called "Awesome" at the $1 store, and it works great on the TM's exterior grime. The wheels haven't been this clean and white since the day we picked up our TM
. I'm still expecting to see some grease flung from the bearings, though...will let you know how much.
