Granite countertops are a favorite in modern kitchen and bathroom design for their durability and timeless aesthetic. However, even this resilient surface can lose its luster over time. If your countertop feels gritty, looks dull, or has stubborn stains, it’s likely suffering from improper maintenance or wear of the protective sealant.
In this complete guide, we’ll show you how to clean and restore your granite countertop, returning it to its original beauty without damage. Whether you’re dealing with an oily spot, gritty residue, or faded finish, this guide will help you troubleshoot and fix the issue.
What Causes Granite Countertops to Become Gritty, Dull, or Stained?
Before cleaning, it’s important to identify why your granite countertop no longer looks or feels right:
- Gritty feeling: Often caused by soap scum, hard water buildup, or leftover cleaning product residue.
- Dull finish: Usually the result of worn sealant, etching, or using acidic/abrasive cleaners.
- Staining: Caused by oils, wine, juice, coffee, or water sitting too long on unsealed areas.

How to Clean Gritty Granite Countertops
1. Use a Granite-Safe Degreasing Cleaner
Grit can form from greasy buildup or dried-on spills. Choose a pH-neutral granite cleaner or a homemade mixture of:
- 1 cup warm water
- A few drops of dish soap (non-acidic)
- Optional: A few drops of isopropyl alcohol for sanitizing
Spray it on, let sit for a minute, then wipe using a microfiber cloth. Rinse and dry thoroughly.
2. Avoid Harsh Chemicals
Avoid vinegar, ammonia, or bleach—these can break down the sealant and leave a gritty or etched surface.
3. Gently Buff the Surface
After cleaning, buff with a clean microfiber towel to restore some shine and smoothness.
How to Restore Shine to a Dull Granite Countertop
1. Clean Thoroughly First
Any polish or sealant must be applied to a completely clean and dry surface.
2. Use a Granite Polish
You can buy a granite polishing product or make your own:
- 1/4 cup baking soda
- Enough water to make a thick paste
Apply the paste, let it sit for 5–10 minutes, and buff with a dry cloth. Rinse off and dry.
3. Re-seal if Needed
If water droplets no longer bead on the surface, your granite slab needs resealing.
How to Remove Stains from Granite Countertops
1. Identify the Type of Stain
- Oil-based (e.g., cooking oils, butter): Needs a degreasing poultice.
- Organic (e.g., wine, coffee, juice): Baking soda + hydrogen peroxide works well.
- Rust or metal marks: Use a granite-safe rust remover only.
2. Make a Stain-Removing Poultice
Poultice Recipe:
- 1/2 cup baking soda
- Add water or hydrogen peroxide (depending on stain type) to make a thick paste
Apply to the stained area, cover with plastic wrap, and leave overnight. Rinse and dry.
How to Prevent Future Stains and Dullness
- Use coasters and cutting boards to avoid etching and scratches.
- Wipe spills immediately, especially acidic or oily substances.
- Clean daily with a soft cloth and mild soap.
- Re-seal every 6–12 months depending on kitchen traffic and type of granite.
