Green Teak - Cure please

[Chris_Stannard]

I recnetly bought a boat with a teak deck which has spots of green mould/algae/? on it. I know not to scrub it except lightly across the grain and this will not get rid of any spores, so the problem might come back.
I do not really want to do the whole deck but guess I may have to. Has anyone got any cures which will remove the green, inhibit further growth and will not damage the teak.
I have been washing down with fresh water since the water in the marina is so dirty but will take the boat out and wash down with salt if that will do the trick.
Many thanks in advance

Garden fence and garden wood deck moss killer, works a treat after a light scrubbing, it will kill the moss and fungus etc. I use it all the time, normally before winter, but you can use it anytime.

Last year I used Dishwasher solution, diluted 50/50, a tip I picked up from a chap cleaning his decks in Haslar Marina. He said he had been doing it for years and that it contained something that is in the specially manufactured teak cleaners but of course it is a fraction of the cost.

This year I picked up a bottle of 'Deckhand' from my local chandlery. Only £1.50 and you dilute it with 20 parts of water. At that price I thought I would give it a go. So far I have only done the bathing platform as an experiment, as it was quite green round the edges. It came up a treat. Next week I shall be doing the decks if the weather stays like this.

Re: Moss Killer

Scott,

Do you know what the active chemical is, does it say on the packing?

Thanks

Re: Moss Killer

I haven't got it here, it's back on the boat, I'm offshore Norway at pres. Its bound to be something biocideish!

Re: Moss Killer

I think you'll find that its just oxalid acid. It will also contain a little bleach which will make the deck a bit whiter.

To be honest, we've tried a number of different things. Oxalid acid was reccomended by our manufacturer, and the wife swears by dishwasher powder and sea water, but I've found that a light rub across the grain with a scotch pad (also reccomended by the manufacturer) and plenty of slightly soapy water always does the trick, as is just as good. Done once a year (and regular hosing downs between times) doesnt take any more teak off than your feet do. Our handbook says that what keeps teak clean is wear (which is why marinas and ferries always look OK), and yachties are too nice to their teak.....

I know a large section of the forum wont agree with me on this, but

disolve ordinary houshold washing machine powder and wet deck, leave for a number of hours, best done on a damp dank day, then wash off with smaoll pressure washer.


Biggest wearer out of decks in use is feet--- so dont use the boat

Followed buy trapped water,

Perhaps another method is needed with thin veneer type decks , but cannot advise as hav only had a boat with 2"" laid planks, and the present one with 3/4 laid on steel.

Re: Moss Killer

The moss killer isn't oxalic, that much I know, but whats in it I don't know. But it's definitely biocide of some sort, as it states keeping away from plants and animals.Also, oxalic and bleach would nuetralise each other, both bleaching agents, one chlorine the other oxygen, I think!!!

Many thanks, I tried a patch at the weekend and it works although I used a much lower concentration than they specified.
