When I looked in the dishwasher this morning after it ran overnight, I noticed an amount of tiny flecks on the white plastic cutting board I have, on both sides of the surface. After taking it to the sink, no amount of scrubbing is getting them out!

-What is it?

-How do I get them out?

-Can I still use it?

    A picture would be very useful.

  • Without a picture I don't think this is answerable I'm afraid.

    Are there knife grooves or other scratches that the spots are in? If so, it'll be difficult to get out without scraping a think layer off of the cutting board to remove the nooks that things get stuck in.

1 Answer 1


As has been indicated, pictures would be helpful for this but without one a simple suggestion would be to try bleach. Depending on the size of your board you can submerge the board in a bleach and water bath or get a towel (paper or cloth) soaked with bleach and water and set that on top of the spots and let that sit for a while.

  • I don't have bleach but I like the suggestion.

    Perhaps a crazy and irresponsible idea, but would taking a light touch of a blowtorch to it help?

    Fire would be unlikely to do anything good for your board.

    Please do not use a torch, at best you'll ruin your board, at worst you will get toxic fumes from it.

    @WeckarE. It would smooth out your board but would be very difficult to do well and would probably warp your board too much.
