Getting Hard Water Off Oil-Rubbed Bronze

Oil-rubbed bronze has a smooth surface that naturally ages with time -- that's part of its charm. What's not charming is the easy damage oil-rubbed bronze sustains when exposed to hard water. Minerals in hard water negatively affect the oil-rubbed finish and create water spots if left on the treated surface. Daily and weekly maintenance reduces oil-rubbed bronze's exposure to harsh minerals and extends the life of the surface. Mild cleaning solutions are required to eliminate hard water without wearing down the fixture's surface; you should always test them in a hidden spot of the fixture to test for cleaning safety.

Clean off mineral deposits from your oil-rubbed bronze fixtures.

Step 1

Pour 1 tbsp. of salt into a bowl and add 3 qts. of warm water to the bowl. Salt is a safe, natural cleaning solution that eliminates hard water spots without affecting the bronze's surface.

Step 2

Dip the toothbrush's bristles into the cleaning solution and gently brush the bronze surface.

Step 3

Rewet the toothbrush in the cleaning solution as the bristles become dry, and continue brushing in a circular motion to eliminate hard water spots.

Step 4

Wet a soft cloth with warm water and wipe off the cleaning solution from the fixture.

Step 5

Rub the oil-rubbed bronze surface with a soft cloth to remove moisture.
