Shower curtain care: polyester may wash, PEVA may need wiping
Polyester curtains may be machine-washable while PEVA/EVA liners may require only wiping or rinsing; follow the label.
Not all shower curtains tolerate machine washing. IKEA Korea lists BANJANTRÄD polyester as washable at up to 40°C but not tumble-dryable, while its BJÄRSEN PEVA curtain must not be machine-washed and should be wiped with a wet sponge. These are product examples, not universal fabric guarantees.
