You can remove rust from granite countertops using granite cleanser, hydrogen peroxide, or poultice. When you’re using a cleanser, all you have to do is scrub it on the rusty area and rinse it away. When it’s hydrogen peroxide, spray it and let it sit on the spot for a day, and then rinse with water. However, if the rust is stubborn and out of your hand, then call the professionals. 🛠️

The above is just a glimpse of this article. To completely get involved in cleaning, you’ll have to learn about the ways in detail. Don’t worry, I’ve explained everything in this article. So, let’s move forward. 🧼✨

Why Does My Granite Countertop Get Rusty?

Before I get into the solution, I’m going to explain the reason you found your countertop rusty.

The formation of rust comes from water that has mixed up with iron and oxide and created a brown/red color. Most of the time, we see rust around a faucet. A very common reason can be a leaky faucet.

Again sometimes we don’t clean the countertop even after it gets into contact with water. The water sits on the surface, and time by time, it forms rust, and your granite countertop shows a rusty color.

  2. Now, get a nylon brush or a scrubbing pad and scrub the cleanser using a circular motion.
  3. Next, rinse away the granite paste and inspect whether the rust has gone or reduced. If it’s getting lighter, then repeat the same process.
  4. Finally, when the rust is gone, seal the granite perfectly.

Method 2: Trying Hydrogen Peroxide

The next method is also quite easy and effective though there are downsides. I’ll talk about this later because first, I’ll discuss how to use it.

  1. Get a spray bottle and pour 4% hydrogen peroxide into it.
  2. Now spray it on the rusty location.
  3. Next, just like the previous method, use a nylon brush and scrub the area. Let the hydrogen peroxide sit on the rusty area for 24 hours
  4. Finally, rinse away the hydrogen peroxide, and hopefully, there will be no more rust.
  5. When the granite is clean, apply the sealing, and it’s done.

Things to Keep in Mind While Removing Rust from a Granite Countertop?

This time here are some warnings for you before you get into the cleaning task. Let’s get them below.

  1. Very often, we hear acidic things are helpful in removing stains and rust. It’s true, but not for natural stones like granite. It can damage the countertop to quite an extent. So, steer clear of acidic solutions such as vinegar, lemon juice, etc.
  2. At the time of scrubbing, never use any metal or steel brushes. It can be disastrous for the natural stone. Its true granite countertops are highly durable and last for a long time, still, they can create scratches.
  3. When you’re using hydrogen peroxide, make sure you maintain the % of the solution. Using more than ideal (3-4%) can highly damage the stones.

What If You Don’t Take Care Of the Rust?

Ignoring rust on your granite countertop isn’t harmless. In fact, it’s a costly mistake with damaging consequences. Here’s what can happen if you leave the rust unchecked:

Progressive Damage

Untreated rust worsens over time, etching deeper into the granite and causing permanent scarring. This damages the stone’s integrity and reduces its value.


Rust interacts with the minerals in granite, leading to unsightly discoloration. The once vibrant surface becomes dull and stained, compromising its aesthetic appeal.


Rust is like a weed, it doesn’t stay confined. It can spread across the countertop, further enlarging the damaged area and requiring potentially expensive restoration.

Remember, preventing problems is always easier and cheaper than fixing them. Taking swift action with the baking soda method I mentioned earlier can save you from these negative consequences and keep your granite countertop looking its best.
