The most effective way to clean granite countertops is with mild dish soap and warm water, applied using a soft cloth or microfibre towel. This simple approach works because granite, while durable and heat-resistant, has a sealed surface that responds best to gentle, pH-neutral cleaning methods. Most granite countertops installed in kitchens and bathrooms are treated with a professional-grade sealer during or after installation, which fills the stone’s microscopic pores and protects against liquid absorption. That sealant layer makes daily cleaning straightforward, but harsh chemicals can break down that protective barrier over time. Granite is an igneous rock composed primarily of quartz, feldspar, and mica, which creates those distinctive speckled patterns homeowners love. Each slab is unique in appearance. While granite has relatively low porosity compared to other natural stones like marble, it still contains microscopic pores and fissures that can trap liquids if the sealant becomes compromised. Understanding this basic structure explains why certain cleaning methods work well and others cause damage. Everyday cleaning method and tools For everyday cleaning, use no more than half a tablespoon of mild dish soap mixed with warm water. Apply with a soft cloth wrung out until just damp, wipe the countertop in small circular motions with light to medium pressure, then dry the surface with a microfibre towel. Moisture left sitting on granite can leave water spots, so always dry thoroughly. Never flood your granite with water; use only as much as necessary. Watch how much soap you use. Each application leaves behind a thin layer of residue that builds up over time, eventually making the surface look cloudy or hazy even when clean. A couple of drops is enough. If you already notice that dull film, cleaning with warm water and drying completely is the first thing to try. If the haze lingers, a small amount of mineral spirits on a soft cloth clears leftover residue effectively. As for tools, always use a soft sponge or microfibre cloth. Abrasive scrubbers, steel wool, and powder cleansers contain particles coarse enough to scratch both the sealant and the finish. For periodic disinfecting, 70% isopropyl alcohol works well and helps restore shine. A...
