How do I remove the sealer before it becomes cured?
A freshly applied granite sealer can be removed, but you'll need to strip it off and that requires a little elbow grease.
The longer you wait to remove a sealer, the more difficult it will be.
How To Remove Granite Sealer Residue
It's not the sealer's fault.
- First try scrubbing the countertop with 0000-grade (very fine) steel wool or a Magic Eraser. This may be sufficient to remove the sealer streaks.
If scrubbing doesn't work... you'll need to chemically strip off the dried sealer residue.
- Pour fresh sealer onto the countertop.
- Agitate fresh sealer by rubbing the surface with a nylon pad or brush for 3-4 minutes. The fresh sealer will combine with the dried sealer residue.
- Wipe the surface completely dry. Wait an hour and note if the hazy residue is gone. If not...
- Repeat steps 2-4 using Methylene Chloride instead of the sealer.

Resealing frequency required will vary from stone to stone. Each slab of granite or marble or slate is different.
The test will tell you if or when your granite could
be sealed (or resealed) and then it's up to you to decide if it should
be sealed based on the intended use and installation location (i.e. if risk of staining is low, then no need to apply a sealer).
