It is not recommended. Many generic household cleaners, especially those with high pH (like ammonia) or those that are acidic (like vinegar or lemon juice), can damage granite. While granite is more durable than marble, its sealant is not. Harsh cleaners will break down the protective seal, leaving the stone vulnerable to stains and bacterial growth. We recommend using a pH-neutral cleaner specifically designed for natural stone or simply warm water and a mild dish soap for daily cleaning.

A simple and effective test is the water absorption test. Sprinkle a few drops of water on your granite surface. If the water beads up and sits on top of the stone for several minutes, your sealer is likely still effective. If the water soaks into the granite and creates a temporary dark spot, it means the sealer has worn off and your stone is no longer protected. This is a good sign that it's time for a professional resealing.

No, sealing does not make granite stain-proof, but it does make it highly stain-resistant. The sealer works by penetrating the tiny pores of the granite, creating a barrier that buys you time to clean up spills before they can cause a permanent stain. It's an essential line of defense against common culprits like wine, oil, and coffee. Regular professional sealing is the key to maintaining your granite's pristine appearance.
