How to Maintain an Old Porcelain Tub

Whether your stunning vintage bathtub is the centerpiece of your bathroom or you’re simply working with an old one, keeping it clean and looking new is essential. But how can you achieve that? We’ve uncovered the best methods for keeping your tub sparkling—keep reading for tips on caring for your porcelain beauty.

What to Avoid

Since porcelain enamel is applied to cast iron, avoid using abrasive cleaners that could damage or chip the surface. Harsh products such as scouring powder, white vinegar, and steel wool should be avoided, as they can harm the tub’s finish.

Recommended Cleaning Products

For a gentle weekly cleaning, choose cleaners that are labeled “safe for porcelain enamel,” or make a homemade solution by mixing a few tablespoons of dish soap with a gallon of warm water. Use a soft sponge or rag to wipe down the porcelain, then rinse thoroughly with water.

For a More Thorough Clean

For a more intensive cleaning, combine ¼ cup of ammonia and ¼ cup of baking soda with a bucket of warm water. Baking soda provides mild abrasion without damaging the enamel, and ammonia helps break down grease and soap scum. Soak a soft sponge in the mixture and gently scrub your porcelain until stains are gone. Don’t forget to rinse off the paste. (This method should only be used once a month.)

Restoring the Shine

Giving your tub a touch of shine is simple! Take a clean cloth and apply a small amount of lemon oil to it. Gently rub the cloth over the sides of the tub – avoid the bottom, as the oil can make it slippery – to leave a light sheen and a sparkling finish.
