Cleaning brake pads and rims

What's the best way to clean brake pads and the braking surfaces on the rim?

For the rim, I've seen some rim blocks which look like a block of sandpaper, that will clean anything off your rim to ensure you have a great braking surface - are these any good?

    Just clean them... in the same way you would clean anything else... don't use solvents, spirits oils or anything stupid... wash up liquid is perfect

    I'd say car shampoo - washing up liquid contains a lot of salt to "soften" water, and also quite a bit of alcohol, which is why it goes all gooey around the spout.

    I use a kitchen washing up brush with some fenwicks to really give the rims a good scrub, nail brush is also good.

    For brake blocks, I remove them from the bike from time to time (when they start to get noisy - preferably just before) and use a sharp stanley blade to pick out the alloy shards that will certainly be in there assuming you're not talking about carbon rims. I also use a sanding block on the blocks to help reveal where the alloy shards are, once you rub the pad, they shine bright making it easy to pick them out.

    PS - This is why I'm looking forward to a disk equipped road bike.
