Hot water, slippery rubber bits, and screw drivers...

Spoke with the blokes at brakemart the other day when i was doing the MC on a volvo (not mine, dont pay me out... please) and they use nothin but metho to clean brake parts. Worked a charm for me, gets the brake fluid off quicker and easier than hot water, and leaves the parts cleaner
