How to Remove Scratches & Stains From Porcelain Enamel Appliances

Updated April 17, 2017

The porcelain enamel found on bathtubs and appliances can easily become scratched and stained. Unfortunately, scratches and stains on porcelain are typically very noticeable and can cause the objects to look unsightly. Luckily, there are ways to remove them from your porcelain enamel appliances.

Use a soft cloth to buff out any scratches in the porcelain enamel. Some scratches will resolve if wiped back and forth with a soft cloth. After you are finished buffing, clean the surface.

Combine warm water and washing powder together to create a dilute mixture. Use this mixture to remove stains that are relatively light or to wash the surface after you have buffed it. You could also use this mixture for routine cleaning.

Combine warm water with baking soda until you have created a paste. Baking soda paste is typically effective on stains caused by dirt. Apply the paste with a soft cloth and work it in until the stain resolves. Wipe off the remaining paste with water or the water-and-detergent mix you created.

Dilute hydrogen peroxide bleach or chlorine with water, then apply the mixture to the stains while wearing gloves. Products such as bleach or chlorine typically have dilution instructions on their labels. Rinse the mixture off the stain with water after a few seconds. You could also add 1 tbsp of trisodium phosphate to 1 gallon of hot water and apply the mixture directly to the stain. Rinse off the area with water after the stain has come out.

Apply acetic and muriatic acids to the stain as a last resort. These products can damage porcelain enamel, so you should use them only sparingly. Apply the acids according to package instructions, and wear gloves.


Store-bought cleaners may work to remove stains from your porcelain enamel appliances. Follow the directions on the label for application instructions. Trisodium phosphate and acetic and muriatic acids are often available at hardware stores.
