How to Remove Stains From Granite Countertops Without Damaging the Stone

If you’re wondering how to remove stains from granite countertops, the good news is that most stains can be removed without damaging the stone—as long as you use the right method. Granite is one of the toughest countertop materials available, but because it’s a natural stone, it can absorb liquids if spills are left sitting too long or if the sealant has worn away.

For over three decades, Cosmos Marble & Granite has guided homeowners throughout Huntingdon Valley and the Metro Philadelphia area in selecting, installing and maintaining beautiful natural stone countertops. Now the good news is that granite can look as spectacular years down the line as it did on installation day – if it’s cleaned correctly!

Key Takeaways

• Most granite stains can be removed if treated with the correct cleaning method.
• Different stains require different solutions—oil, coffee, wine, and rust should not all be treated the same way.
• Avoid harsh household cleaners that can damage granite’s protective seal.
• Resealing granite regularly helps prevent future stains.
• Professional stone experts can restore granite that DIY methods can’t safely fix.

Why Does Granite Stain?

Let’s cut to the chase. Granite is tough and less scratch resistant but it can stain.

Granite contains tiny natural pores. The sealer fills those pores, so it’s much less possible that a liquid really penetrates. As the solvent is extinguished, oils, wine, coffee cooking grease something juice and even cosmetics are going to invade

The sooner you clean up a spill the better off you will be.

Common Types of Granite Stains

When you know what the stain is, that helps your approach to cleaning it.

Oil and Grease Stains

These usually appear in dark spots.

Common causes include:

• Cooking oil
• Butter
• Grease
• Lotion
• Cosmetics

Regular soap does not work as oil gets into the pores.

Organic Stains

Organic stains often come from:

• Coffee
• Tea
• Wine
• Fruit juice
• Food spills

Most disappear leaving brown, pink or reddish spots.

Hard Water Deposits

Mineral deposits, which can manifest in the form of white or slightly cloudy spots on granite when water continually collects around your faucet.

Rust Stains

Rust spots from copper pans, or even other links like metal cans, cast iron cookware or wet steel utensils on the flooring.

Best Way to Clean and Remove Stains From Granite Countertops

Stain removal isn’t a one-size-fits-all.

Start With Gentle Cleaning

Before trying anything stronger:

Wipe away loose debris.

Ensure to wash the region with lukewarm water.

Add a few drops of mild dish soap.

Dry thoroughly, using a microfiber cloth.

However, sometimes that stain just sits on the top.

Poultice With Baking Soda to Remove Oil Stains

On some more serious grease and oil stains, a poultice is occasionally required.

You’ll need:

• Baking soda
• Water
• Plastic wrap

You then mix baking soda with water to form a good thick mixture.

Then:

How to apply the paste onto the stain

Cover it with plastic wrap.

Tape down the edges.

Leave it for about 24 hours.

Remove the paste.

Rinse thoroughly.

Unlike cleaning hides merely surface dried, the poultice pulls oil from the granite pores. If you have an older stain, it might require several treatments.

Remove Coffee or Wine Stains

However, a baking soda poultice is great for coffee and grape/wine stains. A handful of stone care experts suggested including a couple drops of hydrogen peroxide for light granite—when blotting incredibly stubborn natural stains—but ought to be examined in an inconspicuous place first.

Do not ever pour bleach on granite directly.

Clean Hard Water Spots

This means that mineral deposits usually sit on the surface instead of having penetrated into the stone.

Use:

• Warm water
• Stone-safe cleaner
• Soft microfiber cloth

Don’t scrub hard, because hard abrasives can damage polished finishes.

Treat Rust Carefully

Rust is one of the most challenging stains to remove.

Skip homemade acidic cleaners. If you have constant sediment or discoloration from stains, use a rust remover that is safe to apply on granite and other natural stone surfaces or hire a stone restoration company.

What Cleaners Should NOT Be Used?

It is here where many homeowners accidentally inflict irreversible harm.

Avoid using:

• Vinegar
• Lemon juice
• Ammonia
• Bleach
• Abrasive powders
• Steel wool
• Scouring pads
• Magic Erasers on polished stone

Eventually, these products will remove the protective seal or dull the clear finish.

How to Prevent Granite Stains

Related: It is much easier to clean rather than removing the stains.

Habits that you would want to follow:

Clean Spills Immediately

Oil, wine, tomato sauce, coffee and juice is not ever to be sat for hours.

Blot first.

DO NOT wipe super hard and create a mess

Use Trivets and Coasters

Granite performs great with heat, but you want to use trivets and coasters to protect the stone and sealant.

Use Stone-Safe Cleaners

For routine use a simple pH-neutral granite cleaner is usually fine.

Reseal the Countertops

Granite should be resealed on a regular basis, but this does depend on what type of granite you have and how much you use your kitchen.

A quick water test can help:

Simply apply a couple of droplets of water on the surface area.

Wait several minutes.

If it darkens, this is sign that the stone needs to be re-sealed.

When DIY Methods Aren’t Enough

Because in some instances those stains are weeks — and even months old.

For deep oil set-in’s, rust or damaged sealers, you might need a pro to deeply restore than rely on a DIY paste.
