Stainless steel is an essential material in modern kitchens, known for its sleek appearance and durability. However, after multiple uses in the dishwasher, you may notice unsightly brown spots or discoloration on your stainless steel items.
These marks can be frustrating, but they are preventable and manageable.
In this article, we will explore what causes these stains, how to get rid of them, and how to prevent them from recurring.
What Causes Brown Spots on Stainless Steel in the Dishwasher?
Although stainless steel is resistant to rust, it is not completely impervious to damage. Several factors in the dishwasher can contribute to the formation of brown spots:
- Dishwasher Detergent: Many dishwasher detergents contain chlorine or other harsh chemicals that can cause pitting or oxidation on stainless steel surfaces. Over time, these elements break down the protective chromium oxide layer, leading to rusting and discoloration.
- Hard Water: If you live in an area with hard water, minerals like calcium and magnesium can leave stains or spots on your stainless steel. These deposits build up over time and create a dull, brownish appearance.
- Improper Drying: Leaving wet stainless steel utensils or cookware in the dishwasher for too long can cause water spots to form. Heat and moisture, when trapped in the dishwasher, can cause the metal to discolor.
- Overcrowding: When stainless steel items are overcrowded in the dishwasher, they can rub against each other, causing scratches and increasing the likelihood of stains. Additionally, silver and stainless steel should not be mixed, as this can lead to chemical reactions that cause discoloration.
- Acidic Foods: Foods like vinegar, mustard, and tomato sauce can leave behind acidic residues that may react with the stainless steel and cause rust spots. Always rinse off these types of foods before placing your dishes in the dishwasher.

Solutions for Removing Brown Spots
If you’ve already noticed brown spots on your stainless steel, there are a few methods to clean them:
- Vinegar and Water Solution: Fill a spray bottle with equal parts water and white vinegar. Spray the solution on the affected areas and let it sit for a few minutes before wiping it off with a soft cloth. This can help break down mineral deposits from hard water.
- Baking Soda Paste: For more stubborn stains, mix baking soda with a little water to form a paste. Apply the paste to the brown spots and gently rub with a non-abrasive sponge or cloth. Wipe off the paste with warm water, and dry the surface immediately.
- Commercial Stainless Steel Cleaner: For persistent discoloration, a commercial cleaner specifically designed for stainless steel may be the best option. These cleaners remove stains without damaging the surface. Be sure to follow the manufacturer’s instructions for use.
- Lemon Juice: Lemon juice is a natural acid that can help remove mineral deposits and oxidation. Simply rub the juice onto the brown spots and let it sit for a few minutes before wiping it away.
Prevention: Keeping Your Stainless Steel Sparkling Clean
Once you’ve removed the brown spots, it’s essential to take steps to prevent them from reappearing. Here are a few tips:
- Use a Gentle Detergent: Choose a mild, phosphate-free dishwasher detergent that is specifically designed for stainless steel. Avoid using excessive detergent, as this can lead to buildup on your dishes and cookware.
- Dry Dishes Immediately: After your dishwasher cycle is complete, unload your stainless steel items as soon as possible. Allowing them to air-dry or stay in the dishwasher for too long can encourage spots and discoloration.
- Regular Cleaning: Clean your stainless steel regularly using non-abrasive methods. For a mirror-like finish, polish your items with a soft cloth and a dedicated stainless steel polish to maintain their shine.
- Install a Water Softener: If you live in an area with hard water, investing in a water softener can reduce mineral buildup on your stainless steel. Softened water helps prevent staining and prolongs the life of your dishwasher.
