Q We have two matching basins side by side in our master bathroom. One has a dirty ring around the perimeter of the brass drain. I clean it weekly, but a few days later, it’s back. Both sinks are used the same amount.

A Most likely the brass coating on the drain is corroding, causing the ring you have in your sink. Abrasive cleaners and some hair care products, especially hair coloring, can be particularly corrosive. If a family member habitually rinses hair products in the one sink, that could explain why only that sink has the problem.
The best solution is to replace the pop-up and drain assembly. The drains are available (or can be ordered) at home centers and plumbing supply stores. If you want to stick with brass, choose one of the newer types that have a nearly indestructible brass finish. These finishes are applied with an electric charge that vaporizes the brass and affixes it permanently to the drain. Delta Faucet Co. (800-345-3358 or www.deltafaucet.com) is one of many companies that offer this type of product.
Or, replace the brass drain with a nickel chrome or brushed stainless steel drain, which won’t corrode and discolor your sink. To keep your two basins matching, replace both drains.
Also examine the porcelain surface around the drain. If it’s scratched or worn (dull), dirt will also cause a ring. Then replace the sink as well.
