How To Clean Granite Sinks

Nothing adds a look of style and class like a beautiful granite sink. Each granite piece is unique, giving your sink an exclusive look and style. Granite is worth the investment.

A new kitchen sink made from granite will be long-lasting and durable. Granite is resistant to heat, scratches, and stains.

Regular cleaning is essential to keep your granite sink looking its best. Let’s look at what you should use to clean your sink and what you should avoid.

First, Seal Properly

Your granite sink needs to be properly sealed to protect from scratches or erosion. There are many sealers available on the market.

Check with your sink manufacturer to choose the right sealing product for your new granite composite sink.

Cleaning Daily

The best way to avoid the buildup that necessitates a deep clean is by cleaning your granite sink daily. A quick clean after every use will help prevent hard water stains and mineral deposits.

Some soapy water and a soft sponge are all you need for a brief daily clean, no need to resort to harsh cleaning products. Always dry the sink when you’re done cleaning to help prevent both limescale and water spots.

It is easier to prevent stains on a granite sink than remove them. Even with daily cleaning, you will likely see water spots, calcium accumulation, or limescale accumulation if you have hard water.

If you catch hard water spots early, you can often remove them with just a sponge and some hot water. 

White Vinegar To Remove Stains

If your sink develops stains despite your daily cleaning regime, you can tackle them with white vinegar. Mix half water/half vinegar in a spray bottle.

Spray the solution on the sink and gently scrub the problem areas. Rinse the vinegar and dry the sink with a clean cloth.

Don’t let the vinegar solution sit on the granite surface; always rinse thoroughly.

Baking Soda And White Vinegar For Stubborn Stains


If there are still stains on your granite composite sink after spraying and scrubbing with water and vinegar, try a combination of baking soda and white vinegar. Sprinkle the baking soda directly over the stain.

Then use the spray bottle with the water and vinegar solution to soak the baking soda. The two substances will react immediately and start fizzing.

Use a soft sponge to scrub the stained area. Again, remember to thoroughly rinse away all the baking soda and white vinegar and completely dry the area. 

Avoid Any Abrasive Materials

Anything that could scratch your granite composite sink, like steel wool, hard bristle brushes, abrasive sponges, or scouring pads, should be avoided. Always use soft sponges, paper towels , or soft cloths for cleaning. 

Avoid Harsh Chemicals

Although granite sinks are durable and can withstand dropped pots and pans, they aren’t so tough against chemicals. Using harsh chemicals to clean your kitchen sink can damage the color, leaving your sink looking worn out.

Never use bleach to clean your sink.  Many multipurpose cleaning agents can damage natural stone surfaces.

Avoid the use of ammonia, sodium hydroxide, hydrochloride, and sulphuric acid. 

Bad Habits That Can Impact Your Sink

Leaving wet sponges sitting in the sink can leave watermarks or contribute to limescale accumulation. Plastic bowls and drainers build up grit.

This grit can cause scratches on your granite surface. 

Some granite composite sinks can be damaged by heat. Higher-quality sinks are heat resistant.

It is still recommended to avoid putting extremely hot pots or pans directly on the granite.

Granite is harder than aluminum. Dragging aluminum cookware across your granite sink might leave aluminum streaks.

Some foods and liquids, particularly coffee, tea, or fruit juice, can stain surfaces. If you have a spill, don’t delay the clean-up.

The longer a spill sits, the higher risk of a stain.

Restore The Shine

Even a clean granite sink can begin to look a bit dull. You can use some mineral oil and a soft cloth to buff the sink in a circular motion, restoring the sheen and shine.

Enjoy Your Granite Sink For Years
