All you want to do is sand off the oily residue, from the calipers and rotors, very lightly, you will know when its gone, try not to get to much of your finger oil on them either. Hold the edges

Vigorously sanding them will bring them back to new...but you'll have to be careful to not go too far over time without checking the gap's on the cam's and everything...i ran my Old HD disc's till they were too thin and were binding up the brakes and causing all sorts of issues....the new 2.0 discs/pads are much thicker and should last Alot longer.

I use these..Instead of sand paper. Abrasive enough, not so aggresive ...

to remove oily residue why not use denatured alcohol and a cloth,, submerge the discs in there and rub of any excess on the surface

thanks guys, i am just gonna try cleaning them. i don't think sanding them is a good idea. i just don't want to ruin them. back in the day when i raced bmx i used Simple Green on my rims to get the brake pad residue off. that worked really good

i use denatured alchohol then use 800 grit cloth. sanding in a figure-eight motion to ensure the surface stays flat. this will show and fix any minor imperfections.
i would'nt use a dremel.
