Do Granite Countertops Stain When Properly Sealed?

Published on February 2nd, 2021

Granite surfaces feature tiny pores that can absorb liquids, staining the surface. Thankfully, granite is one of the least porous natural stones. When properly sealed, it won’t stain at all. But over time, the seal on your granite counter will start to deteriorate, leaving it open to stains.

To avoid stains altogether, it’s important to reseal your countertops every 1 – 5 years. Otherwise, oily and acidic liquids like cooking oil and orange juice can leave a mark. Wiping up spills as soon as they occur will prevent staining. But even after the stain takes root, removing stains from granite is easier than you might think.
