Topic tags/keywords: cherry finishing question

I’m making a cherry shelf. I used a steel combination square to check alignment during glue-up. In doing so, I briefly set it on some wood I had moistened earlier in the process. Looks like that was all it took…I’ve got the neatest little stain that could have been stamped from the bottom of my square. It isn’t in a noticeable spot so I’ve sanded and will live with what is left.

I’m guessing that like oak, the tannins in cherry cause the stain?
Any ideas for how to remove a stain like this?

Thanks, I’m looking forward to being part of the community.

Oxalic acid should work for you. About a 1/3 cup to a gallon of water. Use rubber gloves and do not breath the Oxalic acid dust when mixing.

Forgot to add this LINK in the first reply to OP. It gives some tips in its use and how to neutralize Oxalic acid.

Read the directions on the container of Oxalic acid as it ican cause skin burns.

Pjones, Thanks for the advice. Next time, I’ll put masking tape on my square to avoid the problem altogether.

maybe buy brass or stainless squares for the future. I am making a cherry and brass on now in hopes to 1. have fun and 2. avoid the problem you encountered.

Thanks again to everyone for the lesson.
Charles, I’m enjoying your preconditioner. It solved a different problem on an earlier project. It was easy to use.

Have your say...
