Thread: Removing Stains from American Maple

Because of image size, I uploaded it offsite - watch for pop-ups if you click on it.



Unknown to me* (until too late!) my verge pointing let go, and the sarking failed... Result is that these pieces got wet several times, and stayed wet. There are the deep blue-black stains, some lighter "watermarks" and a few mould spots of the more usual type; ones that pretty much brush/scuff-sand away.

I'm wondering what is the best course to minimise residual discolouring. Read up in the archive on oxalic acid, chlorine bleaches and oxygen bleaches - still am not 100% sure. I can't immerse the parts, as it will corrode the internal metal rod - but a good slathering from the outside would be fine.

Finish will probably be clear or light amber nitro over a thin base of water-white shellac. Advice would be appreciated; with the present Sydney weather it is hardly going to fix itself!

Thanks, Adam.
