To clean burlap, shake it to remove dust, hang it in the sun for several days, sprinkle it with baking powder, shake the burlap to remove the baking powder, hand wash with cool water mixed with a gentle detergent and let dry. Do not clean burlap using a washing machine.
The first step in cleaning burlap is to eliminate any dust. Fresh outdoor air is important in getting rid of odors, and sunlight helps in bleaching stains. Applying baking powder to the burlap assists in removing foul odors. Hand washing protects the integrity of the material. Lay the burlap flat to dry quickly, preferably outside.
