Drying Laundry Indoors Without Trapping Moisture
Wet laundry adds moisture to indoor air. Dry outside when practical; if drying inside, use a ventilated area, manage condensation and avoid placing clothes on heaters.
UK councils caution that indoor laundry drying and placing clothes on radiators can increase condensation. EPA links excessive moisture to indoor mold. Adapt ventilation to the building, outdoor air conditions and household safety.
