The answer to 'sanitizing smells bad' is that there are several common causes for lingering, unpleasant odors after cleaning. This can be due to improper cleaning techniques, using the wrong cleaning products, or not addressing the underlying source of the smell. Symptoms may include a persistent, musty or chemical-like odor that doesn't go away even after cleaning.
To address this issue, start by checking the cleaning products you're using. Make sure they are designed for the specific surface or material you're cleaning, and follow the instructions carefully. You may also need to deep clean the area to remove any built-up grime or residue that could be causing the odor. If the smell persists, it's likely due to a more serious issue, such as mold or mildew, and you should consider calling a professional cleaning service to properly sanitize and deodorize the affected area.
