Over time, everyday use can cause soap residue, moisture, or general buildup to collect in the overflow opening simply because of its location. When this happens, the sink may occasionally develop a light, unpleasant smell. Fortunately, refreshing the area is simple and can be done with basic household items.
If you notice an odor coming from the overflow, you can use a gentle cleaning method to freshen it. A mixture of baking soda and vinegar can be placed into the opening, where it will lightly bubble as it begins to work. Allow it to sit for several minutes, then rinse the sink with warm water to help clear any remaining residue. This easy routine helps keep the overflow opening clean and supports a pleasant, well-maintained bathroom environment.
