How to Clean Granite Countertops

Granite needs pH-neutral soap and a sealed surface to stay protected. In Tucson's low-humidity climate, sealant dries out faster, so checking your seal every year is smart.

How to Clean and Protect Granite Countertops

Granite is a porous natural stone. Its surface needs a sealant to resist stains. pH-neutral soap cleans without breaking down that sealant. Acidic cleaners like vinegar and lemon juice strip the seal over time and leave dull patches. In Tucson's dry desert air, granite sealant can dry out faster than in humid climates, which shortens the time between seal treatments.

Daily Cleaning with pH-Neutral Soap

Add a few drops of mild dish soap to warm water. Wipe with a soft cloth. Rinse and dry right away to avoid water spots. Never use vinegar, lemon juice, or acidic sprays on granite.

Check the Seal Annually

Drop water on a dry granite surface. If the water beads up, the seal is good. If the granite darkens where the water touches, it is time to reseal. Tucson's dry air speeds up sealant wear.

Stain Removal

For oil stains, make a paste of baking soda and water. Apply, cover with plastic wrap, and let it sit overnight. Wipe clean. For water stains, buff gently with a dry cloth. For deep stains, contact a stone care professional.

What Protects and What Damages Granite

  • Safe: mild pH-neutral dish soap and warm water.
  • Safe: microfiber cloths and soft sponges.
  • Avoid: vinegar and lemon juice, which etch the sealant.
  • Avoid: bleach and ammonia-based cleaners.
  • Avoid: abrasive scrubbers and steel wool.
  • Avoid: leaving spills to sit, especially acidic ones.

Sealing Granite in Tucson's Climate

Granite sealant fills the pores in the stone and blocks stains. Without a seal, liquids soak in and are hard to remove. In Tucson's low-humidity environment, sealant dries out faster than in wetter climates. Most granite needs resealing every 1 to 2 years. Light-colored granite absorbs more and may need it more often.

Alex's kitchen deep-clean includes a granite-safe wipe-down and a check for signs that resealing may be needed. Our crew of 3 to 4 uses only pH-neutral products on granite surfaces. We recommend a stone care specialist for resealing.

How to Clean Granite Countertops FAQ

Can I use all-purpose spray cleaner on granite?

Most all-purpose sprays contain citrus, ammonia, or bleach. These will degrade granite sealant over time. Use a pH-neutral dish soap mix instead.

Most granite needs sealing every 1 to 2 years. Do the water drop test to check. If water darkens the stone, reseal it soon.
