Wet and forget algae remover

[Suffolk Boy]

Hi all

I left my RIB in for longer than I should have done, and the GRP and tubes are now heavily fouled. Tried a pressure washer. Tried a bigger pressure washer with TFR. Most of big stuff has gone but it’s still a mess. Has anyone tried ‘wet and forget algae remover’? Saw it on Amazon and thought I might try. Happy to invest in tools etc if that’s what’s needed, but scared about damaging thr GRP / hypalon.

Thoughts welcome

TFR is alkaline, good for removing algae but not barnacles.

Easy fix though. Been discussed before. See:
Barnacles on a RIB for sale

Dissolve with brick acid and/or Oxalic acid (latter optionally thickened with wallpaper paste), keep it away from a galvanised trailer chassis. Harmless to the tubes but will eat zinc as fast as the barnacles.

Thanks for this. I did see the Oxalyic acid approach - bit worried about the trailer it’s on but I can cover it up I guess.

Will give it a go!

If you've a big enough lawn you can dry launch it or else block it up and remove the trailer. Also discussed before with pics.

Done my fence panels with wet and forget great job but it does say it can take sometime to work

I don't think Wet & Forget would be particularly suitable or cost effective at removing algee from GRP and/or hypalon.
The way it is suppose to work, is to penetrate the surface which it has been applied to ie: wood, concrete, brick and slowly eradicate the algee over a period of time when it rains and reactivates.
I use it regularly on driveways and paths. It's a good product which works well.

There’s different stuff in the range that might work

I have been using wet and forget on our house and fence and stuff for years and it works great. I was doing some research and found out it can be used on vinyl seats for boats.

So I tried it on my white vinyl seat this past spring. It didn't seem to do any better at removing mold as any other product. It really does take a long time to remove the mold on the house so it probably washes off the boat seat too quickly.

I am going to try it again this spring but use it earlier and let it do it's job for a month before actually using the boat.

Thanks for these replies. I’ve got some stuff to try so will give it a spray, leave it for a couple weeks and see what it’s like. Will do before and after photos to post, assuming they aren’t identical.
