When the wooden trim along your doors and walls is exposed to moisture, mold can easily begin growing. Drying out the environment should be your ultimate goal, as this will be necessary to keep the mold from growing back after you remove it. Once you've gotten rid of the moisture by taking care of any leaks or flooding sources that were to blame, you can follow these steps to remove the mold from the woodwork.
Step One: Vacuum up loose mold spores.
First, protect yourself with a face mask (the inexpensive, white variety from the hardware store works well). Also, make sure you're wearing long sleeves and pants, along with gloves, to reduce your exposure to the mold. Then, grab your vacuum, and vacuum over the wood and along the floor at the base of it. Use the wand attachment to give you as much precision as possible. This will ensure any loose mold spores are removed. When you're done vacuuming, take the vacuum bag outside and dispose of it. If you have a bagless vacuum, take the storage compartment outside and empty it so that mold does not get scattered around your home.
Step Two: Soak the wood in bleach water.
Since mold tends to penetrate into the wood, you'll need to use a strong bleach solution to ensure you kill it all. Prepare a mixture of one part bleach to ten parts water, and apply this generously to the wood with a rag. (Make sure you're still wearing gloves to protect your hands not only from the mold, but also from the bleach.)
Let the bleach solution sit there and work its magic for about an hour.
Step 3: Scrub and rinse the wood.
Once the bleach has had time to work, scrub the wood with a stiff brush to make sure all of the (now dead) mold has been loosened. Then, wipe over the wood with a rag dipped in fresh water.
Step 4: Dry the wood as quickly as possible.
Now that the wood has been cleaned up, you need to dry it out quickly so that if there are any lingering mold spores, they don't have time to mature. Start by physically drying out the wood with a cloth. Then, aim a fan at the wood to increase wood circulation. Consider also running a dehumidifier or opening a few containers of silicone desiccant to keep the air around the wood dry.
