Appliance Maintenance to Prevent Mold
Here’s what you should do and how often to prevent mold growth in your home.
Dehumidifiers, bathroom exhaust fans, and kitchen range hoods can vastly improve the air you breathe indoors, but they also have a downside: if not maintained properly, they can become little mold-producing factories.
Consumer Reports says that neglecting to thoroughly clean a bathroom fan or dehumidifier, for example, allows dirt to accumulate and this, plus a little moisture, creates the perfect environment in which mold can grow. Another place you are likely to find mold growth is in a front load washing machines.
Cleaning dehumidifiers once a month is recommended. Yet, according to the article, 60% of the dehumidifiers found in today’s households are not cleaned frequently enough and may be fostering mold growth. Bathroom exhaust fans are another source of mold but only 16% are cleaned every few months as recommended.
Failure to clean these appliances rigorously can also result in the growth of fungi and bacteria that cause lung inflammation.
Here are the recommended cleaning schedules for household appliances:
- Once every few months: bathroom exhaust fans and kitchen range hoods
- Once a month or more: humidifier, dehumidifier, portable air filter/purifier, and wood-burning stove/fireplaces.
- Once at least every six months for a heavy duty cleaning of a washing machine, and once a month or more for regular washing machine maintenance.
So, if you’re the culprit and neglected to clean household appliances regularly, check them carefully for mold. Mold can spread from these devices to other parts of your home, and that can be detrimental to your health – let alone your wallet.

Next comes the all-important bleach wash, which will remove any leftover mold, in addition to stopping future mold growth. In a pail, add 1½ cups bleach to 1 gallon of water. Wet the surface well with this mixture, letting it soak in for about 15 minutes. Scrub the area with the scrub brush. Then rinse well with clean, clear water. Repeat these two steps until all visible mold is gone. Next, use a fan and/or dehumidifier to dry the area well. If you leave any moisture behind, you are leaving your wall open to mold growth.

You certainly don’t want to start your winter with a leaky roof. Check your ceilings for water spots, mold, or stains. If you spot them, before you call in a roofer, have a mold inspector test your home for mold. That way you’ll know exactly what needs to be replaced so the mold doesn’t come back. You may have small stains or dark spots now, but once the heavy snow sets in, the problem could get much worse, and you could wind up with a full blown mold infestation. You should also check your attic for moisture, as mold can easily grow there if it is not properly ventilated.
Indoor air quality suffers in the winter because your home is closed up most of the time. Toxic fumes, including carbon monoxide and volatile organic compounds (VOCs), can be emitted from fireplace and wood burning stove smoke and may back up into the house, which can cause serious health issues. Mold and dust can also build up in HVAC units over the summer months, then spread throughout your home when the heat is turned on. To make sure your indoor air quality is at an acceptable level, schedule a test from an environmental inspector like

If you think you can simply throw away paper files contaminated with mold, think again. Some mold spores have been known to sporulate or “throw themselves” toward moisture sources. Once airborne, the microscopic mold spores can easily float and be carried by the gentlest air currents. Additionally, there may be mold hidden behind walls, in air ducts, under floorboards, and places you’d never think of. It can be detected only through proper testing.
Some people think exhaust fans waste money by sucking out heat and air conditioning, but actually, fans are designed to work with a home’s central forced-air heating and ventilation system – not against them. A recent RTK client found out the hard way that using an exhaust fan properly would save you money in the long run.
The alarming statistic about infants comes from a study conducted at the University of Cincinnati published in the Annals of Allergy, Asthma & Immunology. Researchers analyzed seven years of data gathered on 176 children enrolled in the Cincinnati Childhood Allergy and Air Pollution Study (CCAAPS).
Be sure window air conditioners have proper exterior drainage; keep filters clean.

Below freezing temperatures can cause pipes to burst (when water freezes, it expands which can cause a pipe to burst), which can lead to flooding, and then mold infestation. There is also the possibility they will burst when they thaw, so you may be in for an unpleasant surprise if you weren’t aware it froze in the first place.
