I have used both mothers and wenol to maintain the shine on my frame,, but i have found a polish that is way better than both,,,its called X-TREEM metal polish.
its a big wad of cotton soaked with cleaners. you tear off a little pieces of the pink cotton and use for polishing. i got it a local tire and rim dealer,,,, it works ten times better than mothers and wenol.
its kinda hard to find anymore so heres the address thats on the back of the package
