What's the standard to go by for clean bedding?
Wash your bed pillows in hot water 2 to 4 times a year. Check the washing instructions first for best results and dry according to the label instructions. Wash quilts, duvet covers and comforters 2 to 4 times a year as well. And again, be sure to follow the instructions on the label. If the item is too snug to launder properly in your washer at home, wash it in a large commercial-size washer at your local laundromat.
Your mattress should be vacuumed thoroughly every 6 months to remove any dust mites and dead skin that has settled in there. If not regularly vacuumed, dust mites can create symptoms of allergies such as sneezing, coughing or a runny nose. A clean bed lends to a much better night's sleep.
