Kitchen worktop bubbles

[Mull]

Hi,

Left a damp plastic chopping board on my worktop for too long. Water must've gotten trapped underneath and it's damaged the surface. Thought this may have been calcium deposits so tried leaving vinegar on this and scrubbing but not worked. Any suggestions?

Cheers

what do you think the worktop is made of?

Wood with a thin layer of laminate from what I can tell

Try limescale remover
