<human>:  How do I get rid of mildew on my bathroom walls?
<bot>: The best way to get rid of mildew on bathroom walls is to use a mildew-fighting cleaner. Start by sweeping away any loose debris and wiping down the walls with a damp cloth to remove any dirt or dust. Next, prepare a cleaning solution using a mildew-fighting cleaner, water and a sponge. When the walls are damp, scrub the area with the mixture and rinse away the cleaner. Allow the walls to dry completely and apply a mildew-resistant finish to protect the wall from further mildew growth.
