Glassfibre staining from mucky waters

Used some Y-10 to clean the hull. It worked a treat and took staining out of the glassfibre that elbow grease was not able to shift. It really was as easy as brush it on, and wash it off with a hose and cloth. I’ve done this when the boat is out of the water.

Price is about £10 per jar and it should be available at most chandleries. I reckon a jar should do two hull cleanings.

Y-10 uses oxalic acid so heed the warnings on the jar.
