With the right approach—using safe cleaners, poultices, and proper prepping—you can lift common stains without damaging the stone’s surface. This guide provides practical steps and product recommendations to help American homeowners maintain granite countertops effectively.

What You’ll Need
Having the right tools on hand makes stain removal straightforward. Gather the items below to tackle most granite stains effectively.

- Granite sealer countertop food-safe sealer bottle
- Microfiber cloth set for granite countertop cleaning

Before You Start
Before applying cleaners, ensure the area is clean and dry. Test any product in an inconspicuous spot to check for color changes or dulling. Time estimates vary: plan 30 minutes for routine cleaning, and up to several hours for poultice-based stain removal, including drying time. Critical cautions: avoid acidic cleaners (like lemon or vinegar) on polished granite, as they can etch the surface. Do not use abrasive pads that scratch the stone, and never mix cleaners with bleach or ammonia.
Step-By-Step: How To Clean Stains From Granite Countertops
- Inspect the stain to determine whether it is oil-based, pigment-based, or water-based.
- Wipe the area with a granite-safe cleaner to remove surface grime and prep the stone.
- Dry the surface thoroughly before applying a poultice for deep stains.
- Mix a poultice powder with distilled water or a compatible solvent to form a thick paste following package directions.
- Apply the poultice to the stained area, extending beyond the stain by about 1 inch.
- Cover with a plastic film and tape the edges to keep the poultice moist; let it sit as directed (often 12–24 hours).
- Remove the film and sealant paste with a plastic scraper or soft cloth, then wipe clean with a microfiber cloth.
- Rinse the area with distilled water and dry completely to assess progress.
- Repeat the poultice process if the stain persists, ensuring thorough drying between applications.
- Apply a granite-safe sealer bottle as recommended on the product to refresh protection after cleaning.
- Return the area to normal use once fully dry; avoid placing acidic foods directly for several hours after sealing.
