Having just aquired a boat with teaks decks - much against my better jugdement, but at least they are new - and not screwed down, I need to find a way of cleaning that does not wear them out.

I came accross a guy using an algae killer called MMC Details Here which seems - with one application per annum to keep the decks totally "green mould" free, with no scrubbing. His decks were clean - but grey, which I would be OK with.

Anyone else had any experience of this?
 
Looks feasible - haven't tried this one but happy with the Polycell mould killer from B & Q at about £6/bottle. Applied with a sponge on a dry day certainly effect lasts for 3 months or so.
 
The only teak decks that are brown are the ones you see at boat shows. Grey is how they are meant to be.

I have teak slatted seats and pressure wash them every year. no sign of them wearing away after 7 years.
 
Pressure wash them - gosh you must have some super teak! I have seen the usual AWB teak decks grains noticably striped and groved by just one pressure wash - came up lovely though!!!
 
Whatever you do, don't pressure-wash; it opens the grain something 'orrible.

The benchmark product is Boracol which only comes in quite large amounts and needs careful handling (gloves, goggles). We use polycel 3:1 antimould liquid (B&Q etc) which does much the same, though I believe is about 4x weaker. It clears the green and black stuff brilliantly and leaves the teak looking a pleasantly natural silvery-brown. A second application in the autumn keeps it ok through the winter; it's watery, so easy to apply with a brush.
 
If it is sound teak (and actually is teak) pressure washing should not damage it. I don't have teak decks but I do have cockpit gratings in teak and they are regularly pressure washed.
 
Polycell...

Polycell 3-in-1 Mould Killer is effectively a dilute version of Boracol, and I've been advocating the use of it on these forums for years. My experience of it has been entirely positive. Most "dirt" on teak decks isn't actually dirt - it's mould and algae. Regular treatment with the Polycell product (say every 4-5 months) really works. I've also been using it for years on my sprayhood, again with great results, never any green growth!
 
Disagree...

Kermudjon is right: Boracol is the stuff to use.

Strictly Boracol 10rh (20 rh is stronger than you need) and you can get it from:

a firm in which I have no interest whatsoever, except I bought some from them as the cheapest supplier. Even so about £40 for 5litres but did a super job and even seems to repel starling droppings.
 
Applied MMC Pro the WE before last - decks quite green and very mouldy in places.

Yesterday (Sunday) the deck looked like this

Pressure washing will damage the softer sapwood making the growth ring ( a combination of early wood and late wood cells) stand out giving you a rippled effect on the surface . It doesnt matter what cut of timber you get you will still have sapwood . Some cuts are better but you will always have sapwood .
