jimjimbo Posted August 22, 2016 Share Posted August 22, 2016 This might be "old hat" to most of you out there, but I had the necessity to try and remove some dark black water stains from some walnut veneer on a pair of Forte's I recently acquired in a multiple item deal....I hadn't had to do this previously on any other speaker, so I used "The Google!!", and came up with a method that worked very, very well. Making a thick paste of a common kitchen product called "Barkeepers Friend", I spread it on the stain with a cheap paintbrush, then let it dry. Put another layer on top of that, and then another layer, and let them dry. Gently scraped off with a plastic scraper, and Voila! The stain was gone. There is oxalic acid in the Barkeepers, which reacts with and removes the stain, which is apparently the tannins in the wood reacting with the offending water....Wiped it off with some mineral spirits, then used some Howard's Restore A Finish, and it looks great. Hope this helps someone else that has had this issue. 1 Quote Link to comment Share on other sites More sharing options...
pzannucci Posted August 22, 2016 Share Posted August 22, 2016 Thank you!!! I always wondered if that really worked. Glad to hear you were able to rescue a set of Forte's from Planter (or beer bottle condensation ) destruction. Quote Link to comment Share on other sites More sharing options...
Marvel Posted August 22, 2016 Share Posted August 22, 2016 Barkeepers Friend is great stuff! They also have a liquid, non abrasive version. It works great on mugs with coffee/tea stains. Bruce Quote Link to comment Share on other sites More sharing options...
WMcD Posted August 22, 2016 Share Posted August 22, 2016 Great information. I suppose bar surfaces are drastic examples of water stains on wood on a nightly basis. I thought they have a very tough finish though. Attached is the MSDS for the product. As you say, oxalic acid. But I'd think this would bleach the wood too. What do I know.

It did lighten the wood a touch, but with a little Restore A Finish or other stain applied, you'd never know...... Quote Link to comment Share on other sites More sharing options...
