moisture rings on cabinet shelves
I have some (what I assume) are moisture rings and damage on some cabinet shelves. The marks are all the same purplish color like this. I am trying to research if there is anything to remove or even improve these marks, but for some reason I can't find any information on it at all. I probably don't have the right search terms, I'm not sure what these boards are made of. They have a kind of particle board interior and a sort of plastic-wood veneer on the parts meant to show.
Any thoughts on search terms or even trying to remove the marks?
