Some of you may know that I’m preparing “Riant” for sale and need to give her a good old clean having had her sat on the trailer for over a year. I was given the opportunity to try some Marine GRP and Gel coat cleaner made by a firm called Chemicals Direct who sell various cleaning products on Ebay and elsewhere. I think that they only ship to the UK though.
It comes in a very impressive 5 litre container with a tap and a smaller built in spray bottle. The idea is that you can easily dispense the cleaner from the large container into the spray bottle and dilute it to taste (not literally of course).
I tried it both as a stronger concentrate in the spray bottle and a more dilute mix in a bucket for use with a sponge. Either way it gives your gell coat a really deep clean and I’d say it is really good to clean off grime prior to polishing. If you’ve only ever pressure washed your hull and have a residue film left by algae or salt or whatever this stuff will shift it.
If you are still getting your boat ready for the water and want to give it a really good clean I can recommend Marine Gelcoat GRP Cleaner from Chemicals Direct
I have no connection with this company.
I see that they also make a product called Marine Boat Yacht Carnauba Wash and Wax Cleaner which I may also give a try.
