    Outdoor wood furniture can take a beating from the elements throughout the year. As such, it should be cleaned more than once in a year, especially at the beginning and end of the warm season when it gets the most use. This will not only get rid of any dirt and grime, but also mold and mildew that might have started to grow. Cleaning can even prevent future mold growth that will threaten the life span of your furniture. Follow these guidelines for removing harmful spores so your wooden chairs and benches can look great and last.

    Safety note: When cleaning, never mix chlorine bleach with ammonia-based cleaners, as it creates a dangerous chlorine gas.

    Step 1 – Dry Out Furniture Before Cleaning

    Since mold is caused by too much moisture, theres a good chance mold-infested wood will be damp. Dry it out by sitting it in direct sunlight for several hours before starting to clean.

    Expensive or antique furniture may need to be treated by professionals after you’ve let the wood dry, especially if the mold and mildew growth is extensive.

    Step 2 – Prepare Area and Cleaner

    Step 3 – Dry Scrub

    Step 4 – Rinse with Water

    Step 5 – Scrub with Bleach Mixture

    Step 6 – Rinse and Dry

    • Second, while the black mold I describe is indeed harmless on framing lumber and virtually always came in on the lumber from the lumber yard, also one wants toWatch out: in some cases, particularly on lumber that has been wet, or on treated lumber, my own field and lab tests have found Aspergillus sp. and Penicillium sp. growing among the harmless black mold.

    So we might want to clean the lumber.

This Old House also suggests first cleaning the area with a vacuum that has a HEPA filter. Empty the vacuum bag outdoors. You can remove mold from wood furniture with dish soap, vinegar or borax. Again, avoid using bleach on wood.

If that doesnt work, mix 1 teaspoon of baking soda and 2 cups of water in a spray bottle. Shake it, spray it onto the mold and scrub it with a brush.

    If the mold is really stubborn, you can try using a piece of 100-grit sandpaper, but this must be done carefully. You do not want to sand away too much of the wood surface. After sanding, you will need to vacuum and then clean the furniture.

    Protecting Yourself While Cleaning Moldy Surfaces

    When cleaning mold from any surface, wear protective gear to keep yourself safe. Wear a respirator or air mask of some sort during mold removal to prevent mold spores from entering your lungs. Safety goggles and rubber gloves need to be worn at all times when cleaning up the mold to protect you from certain cleaning products, as well as mold spores.

    If using bleach, wear protective outer clothing or old clothes as the bleach may cause stains. To remove mold from a large area like one that has a strong, musty smell, or one with extensive water damage, you not only want to wear protective gear, but you also want to take a few extra precautions.

Use an old box fan to ventilate the area you will be throwing it away when done as the spores are impossible to clean off the fan.

    Moisten moldy areas while working, turn off furnaces and air conditioners while working, cover ducts and vents, and always leave your wet/dry vacuum outside double-bag and tape all moldy materials before throwing them in the trash.
