In reply to monsoon:
I have some Beal rope cleaner, never actually tried it yet, but the instructions say:
Slip the harness or rope loosely into a pillowcase. Put 75ml of rope cleaner into the Machine, regulated to 30c maximum, without spin drying.
Drying should be done naturally, for example by hanging on a line, whilst avoiding exposure to bright sunlight.
Avoid contact with eyes!
Nikwax do a rope reproofing liquid if you require water repellency.
