I am trying to remove blood stains from a wood tray I had in my refrigerator.

It came from meat I had defrosting above the tray.

I tried bleach, baking soda and vinegar.

Any other methods I can use?

  • (If that's from meat, then AIUI it's more likely to be tissue fluid than blood. I don't know if that affects the solution, though.)

"THE" cleaning solution for blood is hydrogen peroxide (H2O2, "oxygenated water"). You can find 3% diluted hydrogen peroxide in pretty much any pharmacy.

This 3% solution can be used safely even on the human body, and is very useful even on (small) open wounds. It cleans and help healing at the same time.


  • Hydrogen peroxide works best on fresh blood. It has lower efficiency on old blood, or on blood already "treated" with other substances.

  • Because of the low concentration, you might need to use quite a big quantity of the solution, but considering the low price, it should not be a problem.
