VERY light rubbing with white spirit or any alcohol based cleaner/remover.. VERY light, and have a 2nd cloth/sponge reay with just water and wipe over the section you used the alcohol cleaner immediately...

If you do say, 3-4 inches at a time, cleaning off then wiping/rinsing off with water straightaway you should be perfectly fine.

This is how I removed the rubbing strips down the side of my XR3i when I got it and do it this way you won't fuck up the paint
