oxalic acid or a dilute household bleach should do the trick

The black stains are probably bird droppings, not teak oil.
But teak oil on top of bird dropping stains serves to set them.
First use starbright to remove oil, then deal with the stain as suggested above. Work it in across the grain patiently with a toothbrush or similar.

One of the best products i have ever ever come across...seriously !!!
Its a 3 pack system made by SEMCO but not too sure where you can purchase it though. its also very expensive!

I think it retails for approx £150 but will do all the teak decking, grab rails,cockpit gridding and teak fender strips on a 35 foot yacht twice.
I witnessed it in use yesterday, and still cant believe how the nasty black teak came up like brand new with little effort !

Usualy on my previous boat when I cleaned the teak I got at first a lot of dirt and then with the Starbright stuff the black stripes where removed.This time after using the cleaner,I got no dirt at all and some parts are clean and others stay black as if there are trapped in the wood

You can buy a GALLON of the Semco for £96.50 which would last us for years, so I am not too sure about the price you have quoted.

Just don't buy it from Onward Trading - I had terrible service from them a few years ago and then the woman was rude to me when I complained. (I'd paid for next day delivery - but she didn't send it for several days. When I complained i hadn't received it, she said, "Oh but you didn't say you wanted it in a hurry!" - Uh, why did I pay for next day delivery then? etc etc)

oxalic

Can the oxalic acid damage the grp or stain the alloy frame.What is the dilution I can use

I stopped using the Starbright teak cleaner and brightener when I discovered splashes can mark black anodised fittings, such as window frames and genny tracks.
Boracol is good, but it is a mould killer - not a cleaner.

I strongly suspect that may be the same chemicals as Semco.

I have discovered that Semco is stocked by Yachtparts of Plymouth so you can buy it off the shelf. !5% discount if you have an account. No connection - but Semco happens to be the stuff we were introduced to be another forumite (Robinh) when I admired the teak on their boat and its what we use.

There are several 'two part' chemical cleaners for teak around now that seem to darken the teak when you apply it first with a scotch pad and scrub gently, and then are 'neutralised' by the second agent. Perhaps they are all the same really? I know that Semco stings like mad if you get it in a cut.
