I was having the same problem as most, love the look but lots of work keeping them clean. I bought many different foams and stuff, still had to get on my hands and knees to do it. Grease cutting soap does the cleaning job but you still have to rub it on and rub it off. I ended up putting on nonwhite walls, but the bike just didn't look as good.
I'll be going back to White walls next set and getting down on my knees again.
