Hey guys, I bought these rims second hand and the previous owner was using rim brakes, but there is some blue marks left from his brake pads. How would you guys remove this without messing the rims up? I tried a magic sponge, rubbing alcohol, and a few other things, but it didn’t budge. You can see it (only on the rear wheel) in the attached photo. Thanks in advance.
