The ideal way to wash makeup brushes is as follows: wet the bristles with lukewarm water, pour gentle cleanser or shampoo into a bowl, dip the bristles, gently massage, and rinse until the water runs clear. Hang the brushes upside down overnight or lay the brush flat to air-dry naturally to boost hygiene and performance. To clean makeup sponges, saturate them with warm water, apply a sponge-friendly cleanser, press multiple times to lift residue, rinse until clear, and let them air-dry completely for freshness and durability. You should wash makeup sponges after every one or two uses because sponges absorb product quickly. Frequent washing means better hygiene, smoother makeup application, and longer-lasting sponge performance.
