**Using White Vinegar and Plastic Bags**
First, create a simple cleaning solution by mixing fabric softener and white vinegar in a spray bottle and shaking well to combine. Next, spray the solution onto the fan blades and cover the fan grill with a large plastic bag. Turn on the fan, and let the blades spin. The airflow will help disperse the cleaning solution and blow away the dirt and grime. In this solution, the detergent will help remove dust, the vinegar will soften and loosen built-up grime, and the fabric softener will prevent dust from resettling after cleaning.
Once the blades are clean, you can spray the solution onto the fan grill and use a brush to wipe it down. This method will leave your fan thoroughly cleaned and refreshed.

**Using Baking Soda and White Vinegar**
Prepare the following: 2 teaspoons of baking soda, 1 teaspoon of white vinegar, 250 ml of water, a few drops of dish soap, and a spray bottle for mixing. Combine the baking soda and vinegar with water, adding a few drops of dish soap. Stir the mixture until it froths and the baking soda is fully dissolved. Pour the solution into the spray bottle. Before cleaning, be sure to unplug the fan for safety.
Spray the solution onto both sides of the fan blades to soften and remove dirt, grime, and bacteria. Allow it to sit for about 10 minutes, and then plug the fan back in and turn it on. The spinning blades will create airflow, helping to blow away the solution and any remaining dirt.
**Note:** To prevent dirt and solution from spreading inside your home, place the fan in a suitable location like an outdoor area or bathroom, or use a plastic bag to cover the fan and contain the spray.
**Using Toothpaste and a Toothbrush**
For heavily soiled fans, squeeze about 3cm of toothpaste into a small container and dilute it with a small amount of water. Use an old toothbrush to stir the mixture and then dip the brush into the solution. Directly scrub the toothpaste onto the fan grill, focusing on the crevices and along the structural elements of the grill.

**Some Things to Keep in Mind When Cleaning a Fan Without Disassembling It:**
Always unplug the fan before cleaning to ensure safety. Do not allow water to come into contact with the electrical components of the fan to avoid short circuits and potential safety hazards. This method is most effective for fans that are not extremely dirty. If your fan is heavily caked with dirt and grime, this method may not be sufficient, and disassembling the fan for a deeper clean may be necessary. However, for regular maintenance, this no-disassembly cleaning method can be performed frequently, at least once every two weeks, to keep your fan in top shape and ensure a steady stream of cool, fresh air.
