A stainless steel sink is a sleek and durable addition to any kitchen, but over time, you might notice unsightly rust stains. Whether it’s from water exposure, metal utensils, or harsh cleaners, rust can make your sink look old and neglected. The good news? You don’t need expensive products to restore its shine!

In this guide, we’ll explore how to remove rust from stainless steel sink using safe, effective methods. From DIY solutions to preventive tips, you’ll learn how to get rust stains out of your sink and keep it looking brand new.

Why Does a Stainless Steel Sink Rust?

Before diving into how to clean rust from a sink, it’s important to understand why rust forms in the first place. Despite its name, stainless steel isn’t completely rust-proof. Here’s what causes rusting:

• Hard Water Deposits: Minerals like iron and magnesium can leave stains.
• Scratches & Damage: Exposed metal beneath the surface can oxidize.
• Harsh Cleaners: Some chemicals strip the protective layer, making rust more likely..
• Metal Objects: Leaving wet steel wool or iron pans in the sink can transfer rust.

Now, let’s explore the best ways to remove rust stains from sinks—both naturally and with commercial products.

How to Remove Rust from Stainless Steel Sink (7 Methods)

1. Baking Soda & Vinegar (Natural & Non-Toxic)

A powerful yet gentle solution for how to get rust stains out of sink surfaces.

Steps

1. Sprinkle baking soda over the rusted area.
2. Spray white vinegar on top—it will fizz and loosen the rust.
3. Scrub with a soft sponge or toothbrush.
4. Rinse with warm water and dry thoroughly.
5. Best for: Light rust stains on stainless steel or porcelain sinks.

2. Lemon & Salt Scrub (Great for Tough Stains)

The citric acid in lemon helps dissolve rust, while salt acts as a mild abrasive.

1. Cut a lemon in half and dip it in coarse salt.
2. Rub the lemon over the rust stain in circular motions.
3. Let it sit for 5-10 minutes, then rinse.

Steps

• Mix cream of tartar with a few drops of hydrogen peroxide to form a paste.

• Scrub gently and rinse.
• Best for: Delicate surfaces where abrasives might scratch.

4. Oxalic Acid (For Heavy Rust Stains)

Oxalic acid is excellent for removing rust from stainless steel sink surfaces.

Steps:

1. Apply a small amount of oxalic acid cleaner to the stain.
2. Scrub with a non-abrasive pad.
3. Rinse thoroughly.
4. Warning: Wear gloves and ensure proper ventilation.

5. WD-40 (For Rust Prevention & Removal)

Not just for squeaky hinges—WD-40 can help remove rust stains from sinks.

• Apply, let sit, then scrub and rinse.
• ⚠️ Warning: Always test in an inconspicuous area first.

7. Electrolysis (Advanced Rust Removal)

For extreme cases, electrolysis can clean rust from sink parts.
