As far as i know Boracol is simply a wood preservative used to prevent the growth of moulds and algae.
maybe dark patches or marks can be bleached with oxalic acid but have you tried locally treating problem areas with the Starbrite cleaner or tied Starbrite Teak Brightener

If the dark patches are mould growth, then Boracol will remove them. It's not an instant process and you'll only see results after a week or so. One treatment will keep the teak mould-free for, roughly, a season.
If they're not mould but something else, some other treatment will be required.

I used Polycell 3 in one mould remover to remove stubborn stains and green mould on my deck and it was amazing. All the green in the little crevices disappeared almost right away. I've treated it with two coats and will report on how it's done by the end of the season.

Someone here did say (as far as I recall) that terrestrial mould/fungus killers are very toxic to marine life. If you've got a conscience, don't use them afloat.

Don't actually know for sure, but it didn't do any harm to the Twister.
The method of using Boracol is to apply it to the wood with a sponge or a cloth, so it's not slopping about as it would be it it were brushed on.

The active ingredients in the Polycell products are the same as those in Boracol, just more dilute in the Polycell product.

And someone else said that the chemicals soon get bonded to the wood and run-off is negligible. I don't know which is correct, but as long as you don't slop it all over the place it should be safe.
BTW, the black bits will disappear like magic. I've brushed Polycell on for 10 years and have never harmed the nearby gelcoat.

The only possible Polycell product I can find is its Mould Killer. The safety instructions do not make encouraging reading.
"6. ACCIDENTAL RELEASE MEASURES
Refer to protective measures listed in section 8. Contain and collect spillage with non-combustible absorbent materials, eg sand, earth, vermiculite or diatomaceous earth, and place in container for disposal according to local regulations (see section 13). Do not allow to enter drains or watercourses. Clean preferably with a detergent; avoid use of solvents. If the product contaminates lakes, rivers or sewages, inform appropriate authorities in accordance with local regulations."

Yes, that's the stuff, and Boracol has exactly the same ingredients, although more concentrated.

Boracol: Boracol 10RH, 10% disodium octaborate and 2% active Alkyldimenthylbenzyl Ammonium Chloride blended with water and special carriers (water soluble).
Polycell: BENZALKONIUM CHLORIDE<2.5 and DISODIUM OCTABORATE 2.5-10
Doesn't sound exactly the same, although frankly I've no idea what each component does to marine life. I was only reporting what had been said about Polycell elsewhere.

Alkyldimenthylbenzyl Ammonium Chloride is the same stuff as Benzalkonium Chloride, just a different name. It's an algaecide. The point is that Boracol is equally harmful in theory to the marine environment as the Polycell product. The reality, though, is that it soaks in to the teak and doesn't readily wash off.
I've recommended the Polycell 3-in-1 Mould Killer for teak care on these forums for many years. Initially, it was because Boracol wasn't licensed in the UK for amateur use and the weaker Polycell was easily available from B&Q. Today, I buy the more concentrated Boracol and dilute it for use on my teak (and sprayhood) as it works out cheaper than the Polycell product.
