Don't know if you have the inclination or the stamina! /forums/images/graemlins/smile.gif but I just lay them on the pontoon and hose them down and scrub with cif and a stiff broom!
After cleaning the covers they then need to be reproofed. I know that Mastercovers at Port Solent marina provide a sevice for cleaning and reproofing covers
Yep, I used Master Covers tel 02392 374739 to clean and reproof mine, they also replaced a couple of the damaged clear panels etc. Very good service - they charge for the cleaning and re-proofing by weight.
No commercial interest etc etc just very pleased with the service.
