How to Remove Lime From Oil-Rubbed Bronze

Clean the oil-rubbed bronze with two or three drops of dish washing detergent mixed with 1 cup of water. Use a soft rag or sponge to gently rub the lime deposits away. Rinse and then dry the oil-rubbed bronze with a soft cloth.

Apply mineral oil to a soft rag or sponge and wipe it on the oil-rubbed bronze if any lime deposit remains. Do so gently to avoid damaging the surface. Blot the oil-rubbed bronze dry and remove any excess mineral oil with a clean rag.

Moisten a rag with a 50/50 solution of water and white vinegar and apply it on any remaining lime deposits. This method should be used as a last resort because the acid from the vinegar can damage the oil-rubbed bronze finish. Apply the solution on an inconspicuous area first to see how the oil-rubbed bronze reacts. Rinse off the solution thoroughly with a wet rag then dry the oil-rubbed bronze with another rag.

Apply or spray a small amount of car wax on the oil-rubbed bronze to prevent any future buildup of lime and other mineral deposits. Repeat every one to two months as the wax wears away.

Dry off the oil-rubbed bronze with a soft rag or towel if it gets wet. Keep a rag or towel nearby just for this purpose.
