To clean makeup sponges effectively, follow these steps:

1. Wet the sponge with warm water to help it expand and absorb the cleanser.
2. Apply soap such as antibacterial soap, dish soap, baby shampoo, or a specialized sponge cleanser directly on the sponge.
3. Massage and gently squeeze the sponge to work the soap through and break down makeup residue.
4. Rinse thoroughly under warm running water until the water runs clear and no soap or makeup remains.
5. Squeeze out excess water and lay the sponge flat or in a ventilated area to air dry completely.
6. For deep cleaning, soaking the sponge in soapy water or using micellar water before rinsing can help remove tough stains.
7. Additionally, microwaving a wet sponge in a cup of soapy water for about 60 seconds can disinfect it by killing bacteria.

Avoid twisting the sponge while drying to prevent damage and do not store it damp to avoid mold growth. Regular cleaning helps maintain sponge life and hygiene.
