Though commonly used as a wound disinfectant, hydrogen peroxide also works wonders on your granite tops. A solution of hydrogen peroxide removes stains without bleaching or discoloring your countertops. Carefully spread this thick paste over your countertops.
Tackle Tough Stains
In a small bowl, mix 1/2 cup of baking soda and 1/2 teaspoon of hydrogen peroxide to form a thick paste. Double the ingredients if the stained area is large. Spread the paste about 1/4-inch thick over the stain and cover with plastic wrap. Tape down the edges of the plastic wrap to hold it in place.
Hydrogen peroxide is also good for cleaning walls, glass, doorknobs, countertops, toilets, and other hard surfaces.
The Best Way to Clean Granite Countertops
For increased disinfecting power, add isopropyl alcohol to the mix. Isopropyl or rubbing alcohol provides an excellent solution for killing bacteria and viruses like COVID-19 while preserving the finish and shine of your countertops.
Frequent use of vinegar, Windex or bleach will dull the granite and weaken the sealant. Instead, a little soap and water should do the trick. Add dish soap and warm water to a sponge, get a good lather and begin cleaning. Avoid using abrasive pads, as granite can be scratched.
If after a few minutes the water has soaked into the granite, then it's time to reseal the stone. DON'T: Use harsh or abrasive cleaners and sponges. Windex; acidic cleaners, like vinegar, lemon, lime; or anything with ammonia or bleach should be avoided.
Don't use harsh chemicals, acidic cleaners, or abrasive scrubbing tools: Stick with warm water, mild dish soap, and a soft microfiber cloth. Steer clear of vinegar, which can dull the granite and weaken the sealant—though there are plenty of other ways to clean with vinegar around the house!

On granite, sandstone, slate, or quartzite, you can use a 1/2 teaspoon of hydrogen peroxide or a few drops of ammonia directly on the stain and remove it with a damp cloth. Use your normal cleaning solution on marble, limestone, onyx, or travertine.

Add hydrogen peroxide to an opaque spray bottle -- exposure to light kills its effectiveness -- and spray on your surfaces. Let everything bubble for a few minutes, then scrub and rinse clean.
Clorox and Lysol sprays and wipes are convenient, but they are not safe for granite countertops. They rarely contain bleach, but they do generally contain citric acid to help remove soap scum. Avoid using bleach as well.
Windex contains ingredients that can permanently damage the granite. While the most common damage done by Windex is dulling the shine of the countertops, it can also cause pitting.
Granite polishing powder: Also called stone polishing compound, powder offers a quick and easy way to put a fresh gleam on granite while removing minor scratches and stains. If using it dry, choose a buff polishing pad to work the polish over the surface of the granite in a steady, circular pattern.
STAIN REMOVAL Don't panic! Most of the time, stained granite countertops can be cleaned with household items so common that you probably already have them in your pantry. No matter the source of the stain, start with baking soda.

Granite is naturally heat resistant, and heat damage would occur only if the granite was heated unevenly.

That said, we don't recommend putting hot pans on granite countertops — not for the granite's sake but for yours.
Note: Some experts will recommend sealing granite countertops every “6-12 months” or “3-5 years”, but there is no hard and fast rule.
A mix between bleach and water can help remove tough stains, such as food and drink stains, including coffee and wine on sealed granite countertops.
