If your box fan is starting to look a little worse for wear, it may be time to give it a good cleaning. But you don't necessarily need to take the fan apart to do so. Here's how to clean a box fan without taking it apart:
1. Unplug the fan from any power source and lay it on its back.
2. Use a vacuum attachment or brush to remove any dust or debris from the blades and grille.
3. Wipe down the outside of the fan with a damp cloth to remove any dirt or fingerprints.
4. If there are any stubborn spots, you can use a mild cleaning solution on them (just be sure not to get any water inside the fan).
5. Once everything is clean, dry off the fan and plug it back in before turning it on again.
