How to Deep Clean Granite Counters

Granite counters require special care to maintain their beauty and durability. As experienced cleaners know, using the right products and techniques makes all the difference in preserving these natural stone surfaces. This guide walks you through proper granite cleaning, from initial preparation to final sealing, helping you keep your counters pristine and protected for years.
Gather Cleaning Supplies
Start with the right tools for granite care. You'll need mild dish soap, warm water, soft microfiber cloths, and cleaners made specifically for granite. Choose a pH-neutral granite cleaner to protect your stone's finish. Pick up a quality granite sealer for protection after cleaning. Skip harsh chemicals or abrasive tools that could damage your counters. Having the proper supplies ready makes cleaning smoother and safer for your granite.
Prep the Granite Surface
Clear everything from your counters before starting. Wipe the surface with a damp cloth to remove loose dirt and crumbs. Use gentle strokes with a microfiber cloth to avoid scratching. Pay extra attention to edges and corners where grime builds up. Good preparation sets the stage for effective deep cleaning.
Apply Granite Cleaner
Mix your granite cleaner with warm water, following the product directions. Spray the solution evenly across the counter, working in sections to ensure complete coverage. Hold the spray bottle several inches away to spread the cleaner uniformly. Give the solution a few minutes to break down dirt and oils. Don't oversaturate the stone—a light, even coating works best.
Scrub and Rinse
Work in circular motions with a soft brush or non-abrasive sponge to lift dirt without scratching. Focus extra attention on stained areas but maintain gentle pressure. Rinse thoroughly with clean water to remove all cleaning solutions. Leftover cleaner can dull your granite's finish, so take time to rinse completely.
Polish and Seal
Finish by polishing the granite with a stone-specific product. Buff in circles with a clean, soft cloth until the surface shines. Apply a quality granite sealer following the product's instructions. This creates a protective barrier against stains and damage. Regular polishing and sealing keep your granite looking fresh while extending its life.
