How to remove big dark stain from oak cutting board

[taos]

For unfortunate reasons not worth dwelling on, my oak cutting board was left in the sink for a period of time with a silicone pot holder on top of it. When I discovered it, it had a big dark stain where the pot holder was sitting. Does anyone know how to remove this? I've applied a paste of Oxi-Clean, because this has worked in the past to remove stains from plastic cutting boards. Right now it's sitting with the Oxi-Clean paste on it. I can't tell if it's working. Any help would be much appreciated.

It will come clean again with time and use.

I suppose (if it comes down to it) sandpaper and mineral oil might be your avenue of last resort.

In my experience, sandpaper did not work. I had some mildrew stains and I used a sandblaster and it did not work. First, I tried sandpaper and I sanded sanded and sanded and it didn't work. Finally, I borrow a motorized sander and that didn't work either. These stains were really really really deep. I took off more than 1/4 of an inch with planer and sander and they are all there.

I have used Oxi-Clean as the poster suggested and it was absolutely useless. Not the smallest change. I have also tried a few other solutions which help to lighten the stains, but with drawbacks, so I don't know any good solution.

Taos,

Hmmm. Mildrew.
