Put any washable items in the washing machine. This can include linens, clothes, cushion covers and drapes. Wash them on the hottest cycle they can tolerate with your usual detergent and dry as usual. Keep the clean fabrics sealed and away from the mold until the problem has been eliminated in the rest of the house.
Mix 1 tbsp. unscented detergent with 1 gallon of hot water and scrub down all washable surfaces. This includes walls, countertops, windows and large appliances. Scrubbing will remove the mold. Follow with a disinfectant such as bleach.
Vacuum porous, dry surfaces with a vacuum that has a HEPA filter attached. The HEPA filter will catch mold spores and prevent them from returning to the air. These surfaces include upholstery, carpet, wood and drywall.
