Hey... I have a white frame on my bike. Tonight I just spent about 2 1/2 hours trying to degrease and clean the chain, etc....

The frame has a lot of dings on it but I think it is still very solid. My only question is if there is a way to make a white frame look a bit fresher ? There are still some dirt spots that the degreaser didn't get out. I used a rag and some muscle to get the rest out but I was wondering if I might be missing something?
