There are a few things you can do to clean a fog machine if it starts making a strange noise or has started to smoke.

  1. Open the fog machine’s cover and remove any obstructions that may be blocking the air flow.
  2. Remove any filters that may be in the fog machine’s intake or exhaust systems.
  3. Use a vacuum cleaner to suck out any built-up dust and debris from around the fog machine’s internals.
  4. Wipe down the entire fog machine with a dry cloth or paper towel, making sure to cover all of its surfaces evenly.
