Mold gets old

Keep your home environment healthy with these tips for ridding it of mold

Calls come in a steady stream to Oregon State University Extension this time of year from people who don't know what to do when they find mold on the back wall of a closet or under the bathroom sink.

Mold grows on damp surfaces and can cause permanent damage to walls, window frames, carpets, clothes and furniture, said Jeanne Brandt, an OSU Extension specialist for Washington County. 'It looks dirty and smells bad.'

Worse yet, exposure to mold can bring on allergic reactions, asthma and other respiratory problems, especially for young children, the elderly or pregnant women.

Information found on the Internet about mold removal can be inaccurate or extreme, Brandt warned. OSU Extension takes an approach, she said, that is 'reasonable and accurate,' with how-to information and links to the federal Environmental Protection Agency and other reliable sources.

'Sometimes when we take calls, we just try to calm people who are worried about health hazards and cost of cleanup,' she said.

Spores are always in the air and when they grow on moist surfaces they become black, brown or white and look like a furry stain, Brandt said.

'The key to mold control is moisture control; it's important to keep walls, floors, clothing and possessions dry and clean,' she said. Her advice: 'Protect yourself as you clean; wear gloves and open windows. Use a stiff brush and hot, soapy water. Dry the area.'

With no practical way to eliminate all mold and spores indoors, it's important to clean and fix sources of moisture, such as leaky pipes and roofs. The EPA recommends taking steps to reduce indoor humidity to 30 to 60 percent; vent bathrooms and dryers to the outside; use air conditioners and de-humidifiers; and use exhaust fans when cooking, dishwashing and cleaning.

Simpler recommendations are to keep walls, floors, clothing and possessions clean and dry and keep air moving through the house. Leave dirty shoes and boots outside and don't leave wet clothes or towels lying around.

Leave closet doors open and keep furniture and stored items away from walls. Don't close off rooms.
