Q&A for How to Clean a Granite Sink

I recommend creating a paste out of hydrogen peroxide and whitening powder. You can mix them together in a disposable container, such as an old food storage container you no longer need.

Sure! Baking soda is actually a great option to remove hard stains on your granite sink!

This depends on the type of granite that you are working with. Natural granite will require a special sealer to protect it; without this sealer, it will scratch. Composite granite, however, is resistant to scratching and does not require a sealer.

Give it a good scrubbing with a nylon scouring pad with a bit of baking soda. Allow it to dry completely for at least an hour, then apply a thin coat of sealer.

Use antiseptic disinfectant liquid to cleanse and help protect against infection.

This is most likely due to "etching," which occurs when you use abrasive products on granite. This is a pretty complex issue, it would be best to call out a stone-care consultant for a direct guide on how to deal with this. They tend to give assistance for these sorts of issues via phone, so call first.

Try a Mr. Clean kitchen eraser. I use it all the time to clean my black granite sink and it is absolutely effective!

Rinse the area with water, then mix baking soda and water to make a paste. Apply the paste to the stain and let it sit for a few minutes, then gently scrub the paste into the stain using a soft-bristled brush or non-abrasive sponge. Rinse the sink with water and repeat the process if necessary. If the stain persists, try using a mixture of equal parts hydrogen peroxide and water. Saturate the stain with the mixture and cover the area with plastic wrap for several hours. Finally, remove the plastic wrap and rinse the sink thoroughly with water. Always test any cleaning solution on an inconspicuous area of the sink first.
