Cleaning a hull from growth - wait for it to dry?

Ralphy · 04 June 2013, 19:39

Hi guys,
searched but haven't found an answer. We keep our RIB on a pontoon throughout the summer months and without being anti-fouled there is of course growth on the underside, we normally just put it on the trailer give it a once over with a pressure washer and a rag that seems to do the trick, although with a bit of effort.
We'll be going on holiday shortly and plan on taking it out and putting it on the trailer while we're away, does leaving it for a week or so make the task of removing the growth any easier or would it just make the job harder?
Thanks, Ralphy

I would always clean it off wet, it's a bit like a old porridge dish easier to clean after a soak

Yup wet is easier.

Much harder to remove if left.

We had the dilemma last year....definitely do it straight away (I mean begin within minutes of taking it out if you can, it makes it much easier)!

, will clean it when we take it out then.

Spray a bit of bleach on it first as well, comes off much easier.

Once home and you've got the majority of it off try some Oxalic Acid, mixed with wallpaper paste (helps it stick to do its thing). 10 mins with that on and the hull will be like new. Just remember to clean it off fully, including the trailer as it will burn away the galvanising.

We bought something end of last year, I think it was Y-10. We were told it would remove stains and anything remaining. I presume it does the same thing.

Nothing works as good as Oxalic acid. Messy job but worth it. All browning will be removed. It won't work if the hull is gummed up with weed or barnacles etc though. Needs to be power washed first

Y10 is Oxalic Acid at a Marine Price. Oxalic acid is available on ebay for buttons.

What sort of mix is recommended and should you begin dissolving the Oxalic Acid crystals before adding the wallpaper paste or both together? Elsewhere, I've seen a suggestion of 50g per litre in warm water then add 1.5 tablespoons of the paste when cooled. Also, how best to apply it and how much coverage do you get? Goggles and gloves seem to be thoroughly recommended!

Thanks for any advice.

Or you could bring it to KB Boatpark and have it lifted, pressure washed, put on a dolly for you to Y10 / acid clean it, re-pressure washed and re-launched for the princely sum of £90!
