Doing a major clean up on my components and wheels(6 posts)

prior to a full re-assemble. Noticed that on my red Koolstop brake pads, alot of black gunk on the pads which I suspect came from the rims that had built up dirt/grime from previous pads. My wheels are an anodized red with the brake surface being bare alu. Should I use a scotch brite pad to clean the rim surface, how clean does it get the surface, like new?

Aluminum oxide, which results from your brake pads on the rims, is black. I'd just give them a wipe, don't scrub as you may just be hastening aging the rim.
Rolf wheels perhaps?DINOSAUR

I use Simple Green and a lot of elbow grease. I have a lot of time on my hands and wipe down my rims after each ride.

Make sure you sand your tires with and orbital sander to get them nice and clean also!

Have you tried using oil on your rims?

Duh, aluminum is soft and being worn down at a fairly rapid rate due to the abrasive nature of the frictional forces and the grit being applied. You're already sanding down you're rims and in time they'll become concave at the braking surface and useless due to the excessive wear. At this point you'll throw away the rims and pay to have the wheels rebuilt. You can speed this process up by applying additional unnecessary abrassives to the braking surfaces like 3M pads, emery cloth or a file. On MTB's this happens a lot sooner due to all of the grit and additional braking forces.

The way to get the surface "like new" is to buy new rims. Everything else is part of the aging process.

I have never worn out a set of rims, I managed to trash them long before they got to that point, I am in uncharted territory here. Also thought that the black was grime left over from the old black shimano pads. Strange thing is it is worse on one side than the other, so I most likely have one pad contacting the rim prior to the second.

I HAVE NEVER TRIED THIS - but I have been told that vinegar on a rag will do it just fine. Not sure how vinegar and aluminum react to each other.
What I have done is to wipe them with a paper towel after a rain ride. They come brillantly clean then. (mine are Rolfs)
