Granite sinks are beautiful, but they can also be difficult to maintain.

They require regular cleaning to prevent the buildup of soap scum and mineral deposits.

In addition, since granite is porous, water can seep into the sink and cause damage to the surface.

Luckily, there are many ways to clean a granite sink without using harsh chemicals.

Here’s a simple guide to cleaning a granite sink.

Step 1: Remove any food particles from the sink.

Food particles can attract bacteria and cause stains.

To remove food particles, use a sponge or soft brush to scrub the sink.

Step 2: Wash the sink with warm water.

Warm water removes soap residue and helps dissolve soap scum.

Use a spray bottle filled with warm water to wash the sink.

Step 3: Rinse the sink.

Rinse the sink with cold water after washing it with warm water.

This step rinses away soap scum and loosens dirt stuck to the sink.

Step 4: Use a mild dish detergent.

A mild dish detergent cleans without leaving streaks or spots.

Choose one that contains no bleach or ammonia.

Mix one cup of liquid dish detergent with two cups of lukewarm water.

Add a drop of liquid dishwashing detergent to the rinse cycle of your dishwasher.

Step 5: Scrub the sink.

Scrub the sink with a sponge or soft brush.

Rub the sink gently to loosen stubborn stains.

Step 6: Wipe down the sink.

After scrubbing, wipe up spills and splashes with a damp cloth.

Step 7: Dry the sink.

Dry the sink with a towel or squeegee.

Do this immediately after wiping up spills and splashes.

If you don’t dry the sink right away, moisture will condense on the surface and create new stains.

Step 8: Clean the faucet.

Clean the faucet by removing the aerator and running hot water through it for 30 seconds.

Run the tap until all the bubbles disappear.

Then run cold water through the faucet for another 30 seconds.

Step 9: Clean the drain.

Clean the drain in the same way as the faucet. Run hot water through the drain for 30 seconds.

Then run cold tap water through the drain for another 30 seconds. This step flushes out debris trapped in the pipe.

Step 10: Clean the countertop.

The easiest way to clean a granite countertop is to use a mixture of baking soda and vinegar.

Mix equal parts of each ingredient and pour them onto a wet rag.

Apply the solution to the entire countertop and let sit for 20 minutes.

Then scrub the area with a sponge.

When finished, rinse the area with clear water.
