rim wear and tearZvierBoy

Decided I can't sit on a trainer anymore so I took my bike out for some riding this weekend. It was basically a ride where you climb approx. 9km to a hill then ride through several other hills to finally finish after a steep climb on another hill. Total hill ride 16km. It sure makes for one wonderful ride down.
I am using a brand new wheels and after 2 of these rides I the rims have black marks form the break pads surfaces. Is there a way to clean the rims? Water and vigorous scrubbing doesn't seem to do the job.
Are these basically scratches from sand (in some places road was wet form melting snow) getting trapped between the rim and brake pad?

It's a piece of outdoor equipment; it will get dirtyRetro

You can probably remove the marks with something like a Scotchbrite pad (isn't that what those sponges with one scrubbing side are called?). But, jeez, a bike is a piece of equipment designed to be used, not something to hang on the wall. Keep it clean ENOUGH, but spend that polishing time riding instead.

I use a sos pad for my MTB rims. I use this or some cleaner to take dirt off your bike. I use mud off which helps clean both my bikes. The reason I mention the SOS is that's how we clean our rims in the mud seasons.

Don't use Emery cloth or sand paper because that wears your rims down and scratches them. Some spots don't come out, so you just learn to live with it. I mainly clean mine because I rode some rides in the rain and want the brakes to grab better. I'm going to try some aztec brake pads this year.

Hope this helps.

This is part of your braking system--the analog is the braking disc in a car brake. It'll lose it's looks in a hurry, so get over that part. It does need maintainance as do the brake pads. Use Scotchbrite on the rim flats to take off worn brake pad material, use emery cloth or a coarse file on brake pads to remove the shiny appearance.
Also, use a dental pick or small sharp screwdriver to pick road grit and tiny chips of rim metal out of the brake pad surfaces.

Alcohol and a fine scotchbrite will help remove the black from the brake pads.
I use mild solvent (like alcohol) and a scotch brite pad (nm)fishwheel

Do those things take off any of the rim surface like steel wool can? I've never been one to partake of the "sand your rims" ritual. Seems like it just adds to the existing wear and tear of everyday riding.

I like acetone and an old rag when the surface gets really bad. It doesn't come perfectly spanking clean, but that seems excessive anyway. Just get the most of the gunk off.

Recently I switched to Kool Stop pads and they leave much less residue behind and seem head and shoulders above black Shimano pads.

I used to run Ritchey Logic red pads on my cantis and they are much the same from a cleanliness standpoint. I'd say either one is a great choice when compared to black pads. Tend not to get bits of grit and rim embedded.


A. (Does on occasion sand his pads a bit though. Generally when braking diminishes and becomes in need of adjusting.)

I use it on my rims during my wipe down after my rides and it gets all the residue off....use full strength....good stuff
