Another Use For BAC

As a prelude to varnishing Eolian's caprail, I always remove the teak tread plates that I made so many years ago.  And this time I looked at them, really looked at them, for perhaps the first time in years.  The bacteria, algae, and worse, lichen had made themselves a very good home in and on the teak.

Now normally I would have just gotten out the sandpaper, but then it dawned on me to try benzalconium chloride.  I've extolled the virtues of this stuff before, and continue to be impressed with it.  So I sprayed some on the right hand tread in the picture above and let it dry in the sun for a day.  Then I gave it a very light (emphasize light) sanding with 220 to remove the corpses.  What a difference!  And because the BAC is now soaked into the wood, I expect it to fend off colonization attempts in the future.  This has now become an annual task.

Next:  I'm going to spray our unfinished teak rub rail with BAC.  It is equally groady looking.
