IEatFish Posted August 29, 2020 Share Posted August 29, 2020 Hello, my 2nd month in to boat ownership and still afloat with surprisingly no problems! Enjoying the forum and thanks to the home team in managing this. I have a blue canvass type canopy on my boat that is pretty stained to the underside, however it appears water proof, rip free and the bulk of catches and press studs in place. I am planning to take this off when (if) summer returns and clean down and re-water proof on a bright day. Has anyone any advice as to what to clean this with, primarily to the underside and the best re-water proofing agent to use externally? Must dash now as off to my village church to pray for better weather tomorrow and Monday. Thanks Quote Link to comment Share on other sites More sharing options...
ChrisB Posted August 29, 2020 Share Posted August 29, 2020 I always used MC-42 cleaner and re-proofed with Fabsil. Quote Link to comment Share on other sites More sharing options...
MauriceMynah Posted August 30, 2020 Share Posted August 30, 2020 Firstly, let me admit that "Boat cleanliness" is not what I'm famous for, but here my advice is heartfelt. Do not do anything at any time that might affect the efficiency of a folding canopy. If it's stained, get used to it! Only if the canopy needs repairing from damage or wear & tear do anything that might affect it's waterproof qualities, and if you can avoid doing anything, do so. I, my family and some friends have owned boats for neigh on 50 years now, and whenever canopy fabrics have been "improved" (which has happened a lot) they've sooner or later leaked like sieves as a direct result. To paraphrase... If it don't leak, don't fix it! Quote Link to comment Share on other sites More sharing options...
wombat nee blownup Posted August 30, 2020 Share Posted August 30, 2020 Owned a boat now for 12 years. The canopy has been pressure washed annually inside and out (laying on the floor) then when refitted it has had Fabsil applied by roller to the outside. Perfectly waterproof.Sent from my iPhone using Norfolk Broads Network Quote Link to comment Share on other sites More sharing options...
Liberty Posted August 30, 2020 Share Posted August 30, 2020 Fabsil cleaner and Fabsil Gold. Makes the water bead and just roll off. I apply by brush and wipe with a cloth. Superb stuff, makes a real difference. Quote Link to comment Share on other sites More sharing options...
Smoggy Posted August 30, 2020 Share Posted August 30, 2020 For cleaning to keep algae and mildew off use a 4:1 mix of patio magic (or doff from aldi) and brush on and allow to dry, the marine stuff is called wet&forget but far dearer and the same stuff. I've heard of thomsons water seal used to reproof but never tried it. If there's a boat on the tin there will be an extra zero on the price tag.

ranworthbreeze Posted August 30, 2020 Share Posted August 30, 2020 We use Fabsil for proofing the canopy after cleaning. Quote Link to comment Share on other sites More sharing options...
