Remove the drain plug, clear debris and hair, and use a toothbrush to clean the scale from the filter screen.

After bathing, rinse with warm water to remove dirt, then use cold water to cool the surface and wipe dry. For stubborn stains, cover the area with tissue, spray with neutral detergent, wait 10–20 minutes, and then scrub with a sponge.

Use a toothbrush dipped in stain remover paste to gently scrub sebum dirt. Residual soap can promote mold growth, so be sure to clean thoroughly and dry completely.
