How do I clean a porcelain bathtub?

Porcelain bathtubs are durable and relatively easy to clean with the right approach and products. Regular maintenance will keep your tub looking new and prevent buildup of soap scum, hard water stains, and grime.

Start with regular weekly cleaning using a non-abrasive cleaner specifically designed for porcelain or a simple mixture of dish soap and warm water. Apply the cleaner, let it sit for a few minutes, then scrub gently with a soft sponge or cloth. Avoid abrasive scrubbers, steel wool, or harsh chemicals like bleach or ammonia, as these can damage the porcelain finish over time. Rinse thoroughly with clean water and dry with a soft towel to prevent water spots.

For tougher stains and soap scum buildup, create a paste using baking soda and water. Apply this paste to problem areas, let it sit for 15-20 minutes, then scrub gently with a soft brush or sponge. For hard water stains common in Ottawa's water supply, white vinegar works effectively - apply it directly or mix with baking soda for extra cleaning power. You can also use a pumice stone specifically designed for porcelain, but test it in an inconspicuous area first and use very light pressure.

Ottawa's hard water can cause mineral buildup, so consider using a water softener if you notice persistent white or chalky residue. After each use, a quick rinse and wipe-down will prevent most buildup. For deep cleaning, commercial porcelain cleaners like Bar Keepers Friend are excellent for removing stubborn stains without scratching the surface.

Maintain your tub's finish by avoiding dropping heavy objects that could chip the porcelain, and address any chips promptly to prevent water damage underneath. If your porcelain tub has significant damage or persistent staining that won't come clean, it might be time to consider refinishing or replacement as part of a bathroom renovation.
