To clean a keyboard cleaning brush, you can follow these steps:

1. Remove any loose debris from the brush by gently tapping it against a hard surface, like a trash can.

2. Fill a bowl or sink with warm water and a small amount of mild soap or detergent.

3. Dip the brush in the soapy water and swish it around gently to loosen any dirt or debris.

4. Rinse the brush thoroughly under running water to remove any soap residue.

5. Gently shake off any excess water and lay the brush flat on a clean towel to air dry.

6. Once the brush is dry, use a clean comb or your fingers to fluff the bristles back into their original shape.

It's important to make sure the brush is completely dry before using it again to avoid any damage or mold growth.
