Hello Everyone,
My floor is about 3 years old and is starting to bubble in a few places. It doesn't particularly bother me, but there are a couple of areas where it looks like grime has gotten trapped under the bubbles:

This is the worst spot - the others are smaller/lighter.
Any advice on how to get rid of this?
Thanks in advance.
