Is It Safe to Use Bleach to Clean Mold?

For years now, bleach has been used to kill germs, disinfect and clean many surfaces in the home. But when you’re dealing with mold, is it the best option for cleaning?

Read on to find out why bleach may not be your best or safest option to clean and kill mold.

Cleaning Mold

Mold is that nasty little fungus that grows in spaces where there’s darkness, dampness and moisture.

Mold is not only unattractive, but if left untreated, it grows, spreads, stains and causes damage by eating away at structural components and furnishings in your home. It also worsens breathing and other pre-existing health conditions.

Obviously, you want to clean up mold before it quickly begins on its destructive path.

While many people immediately reach for the bleach to clean, disinfect and remove stains left behind by mold, you may want to think twice about bleach as your go-to cleaning option.

Using Bleach to Kill Mold

Bleach works really well to clean up mold on non-porous surface like sinks, tubs or tile. This is because the roots or mold membrane can’t penetrate non-porous surfaces and it’s fairly easy to remove, clean and disinfect the area.

But when mold gets into porous surfaces like fabric, drywall or wood, the roots can and will spread deeper into the material to feed its growth.

While you think that cleaning mold on the surface of porous surfaces has resolved your mold problem, all you’ve done is to wipe away what you can see on the surface.

Bleach doesn’t kill off the deeper, spreading spores and mold roots that penetrate into porous materials like the structural components of your home. This explains why even though you’ve cleaned the visible surface mold with bleach, it can and will grow back with a vengeance because the roots are still alive and spreading.

The Health Risks of Bleach

If you’ve ever been in a confined space after cleaning with bleach, you know how strong and overpowering it smells.

Inhaling bleach fumes causes irritation to your eyes and mucus membranes, while exposing sensitive skin to bleach can irritate and burn.

Accidentally mixing bleach with other cleansers or ammonia-based products creates toxic chlorine gas which is what causes that burning or stinging sensation you may have experienced in your skin, nose, eyes and throat.

For those with compromised immune or lung conditions, chlorine gas negatively affects breathing and lung function.

Why Bleach may not be the Best Option for Cleaning Mold

Some other concerns about using bleach to clean mold is that bleach is comprised primarily of about 5% sodium hypochlorite and water.

Since water is what you want to eliminate to further prevent the spread of mold, spraying bleach on porous surfaces allows the water in bleach to absorb into porous materials. The porous materials soak up the water and feeds it to the mold root, which actually helps mold spread.

Another concern is that since bleach removes color from fabrics, you cannot use bleach on furniture, draperies, clothing or cloth shower curtains. Bleach can also damage or discolor wood, drywall or other structural components due to its corrosive nature.

Effective Alternatives to Bleach

Before using bleach to clean, disinfect and most importantly kill mold at its root, reach instead for white vinegar or tea tree oil. These more natural and non-corrosive cleaners disinfect, kill mold and are safe, healthy alternatives to bleach.
