Tips For Cleaning Mold
- Remember that your goal is not to kill the mold spores, but to remove them. When they have been removed completely they cannot grow back.
- Ventilate, ventilate, ventilate! Ventilation is important during cleaning, so that any disturbed spores exit the building. Close and tape off doors to the rest of the house and use a box fan in a window pointing out while cleaning. This will prevent spores from invading the rest of the home, and remove them from the air of the room to be cleaned.
- Be sure to spray and then wipe all surfaces with a damp rag. Dry wiping will disturb spores and send them into the air! Airborne spores can regrow in new locations, and cause even more mold to grow. Mold spores are not visible to the naked eye, so be sure to cover all surfaces with your cleaner of choice, even if they look clean.
- Do NOT use a vacuum to clean mold unless you have a vacuum with a HEPA filter. HEPA stands for high-efficiency particulate air, which means the filter can stop most particles of dust, pet dander, allergens, etc. that are 0.3 microns or larger and keep them from being put back into the air. The HEPA filter should be changed periodically to increase efficiency. Use with caution as mycotoxins may not be filtered out even when using a HEPA vacuum. Remember that you will eventually have to empty the vacuum, and it will be filled with the mold. Vacuuming is not the best method of removal.
Is Mold In Attic Common
Yes, attic mold is common because it can be found in any property, old or new. The condition for the growth of mold is abnormal moisture levels in the attic. Although attic mold can be found in all homes, research has shown that older homes are at a higher risk of attic mold infestation. This is because they often have faulty insulation that allows moisture to penetrate, thus creating suitable conditions for mold growth. The most common type of mold that grows in attics is Penicillium and Aspergillus.

So, check your bathroom fan vents to see where they are venting to. If you are up north, they should be venting to the exterior.
