How to get rid of tiny black spots on white plastic cutting board? 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?
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.
