Start with construction, not just the item name
Shower curtains and liners can be fabric, vinyl, PEVA or other plastics. Material and care label determine whether machine washing is suitable and whether any dryer heat is allowed.
Choose the washing method
Identify whether the item is fabric, vinyl/PEVA or another coated material and follow its label. Material determines heat and agitation tolerance.
Control the main risk
For machine-washable curtains or liners, use a gentle cycle and compatible water temperature. Heat can deform some materials.
Dry without undoing the wash
Hang dry unless the label explicitly allows tumble drying. Heat sensitivity is often high.
When to stop and follow the manufacturer
If the item has electronics, specialty coatings, dry-clean-only instructions, non-removable structure or a conflicting care label, do not force a generic home-laundry method. The product or finished-item instructions take priority.
Item construction, filling, coatings, electrical components and trim can change the safe method. Follow the finished-item care label and manufacturer instructions when they are more specific.
