I have a teak deck and there are many grey spots on it, mainly on the North side of the boat (in the normal mooring). Can anyone tell me what they are and recommend a cure?

Hi, Have you tried scrubbing the deck with a very firm scrubbing brush? If not try it and if that doesn't work try sanding the deck around the spots or maybe even the whole deck and apply a proprietory teak sealer/preserver. hope this helps.
PS just scrub using salt water only and plenty of elbow grease.
Best regards Bert

No elbow grease

Sorry but vigourous scrubbing of teak is a BAD idea. It removes the softer grain and leave the teak very ridged, and more likely to attract dirt in the future. Oxalic acid is the usual recommendation. Do a search here and you'll find several threads covering it, I suspect.

Boracol...

Hallberg Rassy recommend using Boracol (a timber preservative and mildew preventer). It's a thin colourless liquid. HR recommend that you paint it over the deck on a dry day, and leave it to penetrate. Then, 3 days later, you wash the deck. Apparently, this gets rid of mildew spots.

I haven't tried this yet, but it's on my list of things to do! Personally, I'm tempted never to buy another boat with teak decks. Treadmaster is much more satisfactory in the long run.

The best advice for washing teak decks seems to be to avoid using any sort of stiff brush. I use either a 3M pad, or one of those foam-filled sanding pads you find in DIY stores. Scrub across the grain - never along it.

Try Starbrite Hull cleaner.

Just brush it or spray it on and hose it off after a few minutes.
It also is brilliant for cleaning GRP with no rubbing.

There is a special stain remover for teak which is based on the same chemical. Contact Marine and Industrial sealants 01692 538263
