Penetrating stains, older stains, and knife gouges in butcher block will require some “muscle” but they usually can be removed!
- The first step is to try and remove the stain by sprinkling kosher/table salt on the stained area and rubbing with a damp sponge for a few minutes. Always rub in the direction of the wood grain to avoid further scratch damage. If the stain is still present, continue to step 2; otherwise, wipe clean and move on to step 5 to finish up.
- Stubborn stains or deep scratches will require sanding. There is no set “grit” or coarseness of sandpaper to use. You will want to experiment, starting with a finer grit and working to a coarser one, until you find the grit that works.I can’t say this enough – always rub in the direction of the wood grain (not against it). Trust me, you will be tempted to do so, but please don’t, or risk further scratching the board.Once you see the stain or scratch is being removed, stick with that sandpaper. Remember: the higher the number, the finer the grit.Given butcher block is a very hard wood, it makes sense that you will need to use a coarse grit in the range of 80 to 100 to correct the problem.
- I would start with 150 grit and if that does not work, move to the 100 grit or 80 grit.
- When the stain is removed, be sure to use a couple different grit papers to sand the area to a smooth finish again. Use the 150 grit first, then finish with a 220 grit paper to restore the smoothness.
- Wipe the butcher block with a damp, soapy wash cloth to remove sanding dust and dry thoroughly.
- You must treat the exposed surfaces with a food safe mineral oil to protect and moisturize the wood. The best cure is to apply Boos Mystery Oil to penetrate the cutting board and restore the moisture. Then follow with an application of Boos Block Board Cream to put a protective seal on the block and reduce the chances of future spills penetrating the wood.
- Remember, you should apply oil or cream to your butcher block once a month to keep your board healthy.
