We have an anticado-surfaced absolute granite counter that we think wasn't cleaned properly before sealing. There are areas that just look dirty, like it did on the outdoor lot, but appear to be under the sealer now. Is there a way to safely remove the sealant so we can clean and re-seal it?

We bought a scrap for a small area of counter just around the sink - the rest of our counters are wood. I think the fabricator just didn't care about doing a quality job on such a small project. It was a couple hundred dollars for the stone and a couple hundred more to cut the sink hole and edge the piece with a simple relief, and we were doing the installation ourselves. They sent us home with the matching backsplash pieces uncleaned and unsealed, insisting they were sealed. Once I brought them back in to show them, they realized they normally don't seal backspashes in the shop because they do it after installation. They cleaned them up, removing the same kind of dirty areas we are seeing in the counter, and sealed them and they look fine.
