Ever notice those little grey scratches on your porcelain sink and think, “Where did those come from?” You’re not alone.

The good news is that those marks aren’t actual damage. Most of the time, they’re just residue left behind by metal utensils, pots, or pans that have been rubbing against the surface.

And you can get rid of them easily too!

You don’t need to run out and buy some expensive cleaner or call in a professional. All it takes is a few things you probably already have lying around the house and a little bit of effort.

In this post, I’ll show you how to get rid of those grey scratches on porcelain sinks.

#1 Baking Soda Paste

First up, we have baking soda. It’s not just for baking! It’s also an awesome, natural cleaner that can do wonders for your sink.

If your porcelain sink has grey scratches, try using a baking soda paste. It’s gentle but effective—perfect for scratches that aren't too deep.

Here’s how to make the paste: Take some baking soda and mix it with just enough water to form a thick paste. You don’t want it too runny—aim for something that sticks to the surface without dripping.

Now, take a soft cloth or sponge (avoid anything too abrasive like steel wool—it could make things worse), and gently rub the paste onto the scratches.

Use small, circular motions. Baking soda is mildly abrasive, which means it can buff out the marks without damaging the porcelain.

Give it a few minutes to work its magic, and then rinse it off with warm water.

You should see those grey marks start to disappear!

#2 Pumice Stone

If baking soda paste doesn’t quite do the trick, you can use a pumice stone.

This might sound a little old-school, but it’s a tried-and-true method for removing scratches on porcelain sinks.

A pumice stone is gentle enough for porcelain sinks but are naturally abrasive and tough enough to tackle those grey scratches.

The first thing you’ll want to do is wet both the pumice stone and the sink. This is important because a dry pumice stone can be too abrasive and might cause more harm than good.

Once everything’s nice and wet, gently rub the stone over the scratched areas. Use light pressure and keep the stone moving in small circles. You’ll probably notice the grey marks fading away pretty quickly.

When you’re done, rinse the sink thoroughly and give it a quick wipe-down with a soft cloth.

#3 Bar Keeper's Friend

Bar Keeper's Friend can also remove grey scratches on porcelain sinks quite easily.

If you’ve never heard of it, it’s a powdered cleaner that’s great for tackling tough stains and marks. People swear by it for everything from cookware to bathroom tiles, and yes, it works on porcelain sinks too.

To use it, sprinkle some Bar Keeper’s Friend powder directly on the scratched areas. Take a damp cloth or sponge and gently rub the powder in. Again, use circular motions and don’t scrub too hard.

The powder will help lift the scratches while restoring some of the sink’s shine.

After you’ve rubbed it in, rinse the sink thoroughly. You should see the grey scratches disappear or at least fade a lot.
