Hard scrubbing and teak should never meet. It would look good after this treatment, the trouble is that after a few treatments like that there'll be no teak deck left to scrub or look good!

I suspect you don't have a teak deck! Scrubbing is the very worst thing you can do to a teak deck.

If you want to be really cheap then scrub across the grain with seawater. ;-)
The colour of the teak after Boracol is admired by others who spend a whole week scrubbing a deck in stages - if
Your a MOBO you will know about 2 part ;-)
Dangerous for the SABO owner, unless rollin in cash for new teak decks

Nothing ounce a year, fairy liquid from your sink does more.

Thanks for all the advice in this thread. So it looks like a gentle wash across the grain with a sponge ( someone recommended biological laundry detergent dissolved in warm water) followed by a treatment with Boracol.
By the way, why are so many folk anti teak? Yes it's expensive initially but nothing looks better or provides better non slip characteristics. I know of several teak decked boats well over 30 years old still looking great. Like everything else if it's a quality job to start with and looked after there should be no problems in our climate at least. Having said that, earlier this year I saw an immaculate boat in the Caribbean over 90 years old with the original teak decks - according to the professional skipper.

Why? All you have to do is spray on Patio Magic and leave it for the rest of the year. No washing required.

I think the problem with teak is that there is a lot of variation in quality and it is very difficult to get good teak these days. The stuff you refer to on old boats was mature forest teak plundered from the rain forests and is rock hard. We are not allowed that any more and modern boats are clad in plantation teak. Ours is noticeably softer than the decking on boats built 30 years ago.

The Boracol recommendation is to apply it, leave it a few weeks so that it can kill the fungus, then give it a gentle wash with a mild soap to clear the dead fungus And spores. Having followed these instructions, I can confirm that it works well.

Environmental Safety: ADBAC is highly toxic to fish (LC50 = 280 μg ai/L), very highly toxic to aquatic invertebrates (LC50 = 5.9 μg ai/L), moderately toxic to birds (LD50 = 136 mg/kg-bw), and slightly toxic to mammals (LD50 = 430 mg/kg-bw).[7] Benzalkonium chloride formulations for public use tend to be based on 5-10%w/w. Concentrated solutions (10% or more) are toxic to humans, causing corrosivity/irritation to the skin and mucosa under prolonged contact times, and death if taken internally in sufficient volumes.
Does nobody on this forum care about the environment? Are teak decks to be kept clean at any cost to mother nature?

Patio Magic is absorbed by the teak it isn't washed off and doesn't go into the sea.
So people are quite happy to use antifoul, which must harm the environment otherwise it wouldn't work, but get upset about soaking teak with a biocide which is not going anywhere near the sea.

I do not understand your concern.
You spray on patio magic and it's left to dry. There is no residue to wash off into the sea, come rain or submerged decks.

Just because it dries on the deck does not mean the residue cannot be rewetted and washed off the deck next time it rains. There must be a residue otherwise it would not work as described. I do not believe much of it will be 'absorbed' by the teak deck otherwise rain would be absorbed and teak decks would not be used as decks. And what about the spray that misses the teak and falls on other parts of the boat?
This product is for patios which mostly will be some distance from a watercourse or the sea and at worst it will filter down through the soil below. The truth is this product should be banned but so far it has presumably slipped through.
I do hope sailors think hard before they use it on boats which by definition are going to be on or near a watercourse or the sea.

The entire superstructure of my boat is teak. I use about 3L of patio magic mixed with 4 parts water once a year.
If rain could wash away the patio magic then it would not look pristine for a whole year.
It matters not to me if you want to make hard work of cleaning your decks, you must have fun with an unantifouled hull.

I think a lot of progress has been made with anti fouling products to make them more environmentally friendly. I use Coppercoat which I believe is non polluting but none of this detracts from environmental issues surrounding your deck
cleaning product. You have hit the nail on the head with your remark about making hard work. It seems you would prefer an easy solution and the environment can go to ........Sad, but my case will rest here.

For the very last time, my method of keeping teak, and ropes! clean does not harm the environment.

I wonder if you could explain the leaching mechanism allowing the active ingredient to leave the teak after reacting with the hydroxyl groups in the wood. Do you have a specific reason not to accept that the active ingredient in Patio Magic is biodegradable as stated by manufacturers and others?
I manage with around 250-500mls applied by brush 2-3 weeks prior to launch. No run-off and never applied when rain forecast (as this would be a pointless waste). So the Patio Magic is not near water for a long time after application. I can't see how any significant free unreacted material would enter a water course.
The above is not based on data from excess pesticide running into a water course nor airborne sprays. I was thinking more of direct absorption into wood with easy control of run-off.
