I know that you use a solution of oxalyc acid to get the black stains out of wood. I've even bought some oxalyc acid crystals but what do I do now? I cant throw the crystals at the cabin sides.
Please does anybody know what the solution is, what neutralises it etc. Any guidance would be gratefully received

Just keep adding the crystals to hot water slowly while stirring, until no more will dissolve.
It's a good idea to add wallpaper paste to thicken the mixture so it doesn't simply flow off.
No need to neutralise, just wash off with a hose or pressure washer after 10 minutes or so (not time critical)

A & B bleach is in my opinion better on wood. Paint on the A, allow to soak in then apply the B, there will now be a slight chemical reaction and the black stains will come out. Oxalic is good for making Teak look like new but dosen't go so deep. My mast was black top to toe, liberal use of A & B now looks like new. Just wish I had the boat to stick it up on!

Thanks for that. If I ever get a GRP boat I'll remember.
