Regularly check for mold in the areas you normally don’t go.
Make sure you check for mold in those areas in your house that you don’t go to regularly because it can grow just off humidity in the air and on almost any surface. If you spotted some, don’t try to clean it up the way you’d deal with dust: mold will come back very quickly.
Saves on flashlight batteries, too.
Use a damp paper towel.
