I have this bathroom/laundry sink that goes on top of a vanity cabinet with what I believe to be a layer of fake veneer. I've had noticed these light stains a while ago, probably from small spills of some corrosive solution I used to clean some rust from metal bits a couple of month ago.

I would like suggestions on the cheapest and easiest way to fix, thanks.

    Search for white stains and you will find many possible fixes to try. But top looks like melamine as used in kitchens, so maybe this can't be fixed.

    Highly unlikely this is wood veneer. Nobody with any sense would build a vanity top with a wood veneer surface, so I think the first two commenters are right, and it's a phenolic laminate. That, and given what you think caused the spots (a caustic solution), probably means they are not stains, but rather bleaching of the laminate. I doubt you're going be able to repair it in a way that matches the surface any better than the spots do.

  • Based upon the comments and your description of 'fake veneer', I agree that this question fits better in the DYI site and will transfer it there. Good luck getting answers.
