Step 2: Fill Sink With Water

After plugging the drain hole with a drain plug, you need to fill the sink with water. You do not want to flood the sink. Instead, use the faucet to fit the sink with about 1/4 of an inch of water.

Step 3: Buff Top and Sides with Pumice Stone

Now you can take your pumice stone and get to work on the scratches. If there are any marks on the inside of the sink, use the pumice stone on them. Start with the marks and nicks on the top and sides of the sink.

Instead of scrubbing wildly, you will work methodically. First, dip the pumice stone in the prepared water at the bottom of the sink. Use the pumice stone to buff in the direction of the scratch with a backwards and forwards motion. You should see the mark go away as you buff.

Step 4: Remove the Plug

After buffing away scratches on the sides and top of the sink, you can let the water go from the sink. Remove the drain plug before going on to the next step.

Step 5: Buff Bottom with Pumice Stone

Once you have removed the water from the bottom, check to see if there are any marks. If you see more scratches on the bottom of the sink, you can use the pumice stone there, too. Use the same motion that you used for the top and sides.

Remember that the proper way is to go back and forth in the direction of the mark. Scrub with the pumice stone until you see the scratch disappear from the sink’s surface.

Step 6: Use Baking Soda

For any marks that are still difficult to remove, you can try another method. Porcelain scratch removing with baking soda is simple and effective. You cover the nick with baking soda.

Then buff it with a damp rag in a circular motion. Afterwards, you will rinse the leftover baking soda down the drain with water.

Step 7: Bleach the Sink

This step may be necessary if you are not satisfied by scrubbing with a pumice stone or baking soda. Bleach needs to be used carefully due to its chemical composition. You can also skip Steps 1 through 6 and try bleaching the sink first.

To bleach your porcelain sink for porcelain scratch removing, start with an empty sink. You will plug the drain and fill the sink with warm water. Add one to two cups of bleach to this warm water.

After letting the bleach solution sit through the night, you can let the water out. You should be left with a brighter white sink that is free of scratches and marks.

Removing Aluminum Scuff Marks from a Porcelain Sink

Pots and pans made from aluminum can leave behind ugly scuff marks on your porcelain sink. To get metal marks off porcelain sink, follow the steps below. You will need baking soda, a washcloth or rag, and bleach.

Step 2: Scrub Marks

After laying down the baking soda, grab a washcloth or old rag. Use the washcloth to scrub the sink thoroughly. After working at the marks with the rag, you can rinse the sink with water.

Step 3: Spray Glass Cleaner

If there are still aluminum scuff marks on the sink, use a glass cleaner. Spray the cleaner on the scratches. Using your washcloth, wipe the sink clean. You can repeat this step several times until you see the marks disappear.

Step 4: Fill Sink with Hot Water

For stubborn scuff marks, you may need to follow the last few steps. First, you will fill the sink with hot water. Add enough water to cover the marks completely.

Step 5: Pour Bleach into Water

Add bleach into the hot water sitting in the sink. You should only use about two tablespoons of bleach for every gallon of water in the sink.
