3 Ways to Kill Mold Naturally

3 Ways to Kill Mold Naturally
94 comments

By Annie B. Bond, author of Home Enlightenment (Rodale, 2005).

A proliferation of mold and mildew can be the hallmark of hot and humid summers. I have a friend who has green mold growing on the shoes in her closet! A humidifier might be the best help for her, but there are also three natural materials that can be used as a spray to kill mold and mildew. They are all an excellent substitute for less environmentally safe bleach.

Learn these three tricks for killing mold and mildew. One of these you most likely already have in your kitchen cupboard.

Over the years I have found three natural ingredients that kill
mold: Tea tree oil (an essential oil found in most health food
stores), grapefruit seed extract and vinegar. There are pros
and cons of each, but all three work. Vinegar is by far the cheapest.
Tea tree oil is expensive, but it is a broad spectrum fungicide
and seems to kill all the mold families it contacts. The problem is
that it has a very strong smell, but that dissipates in a few days.
Grapefruit seed extract is also expensive, but has no smell.
Click here for how to use these three ingredients in your home to
kill mold and mildew.

Mold can be dangerous to your health, even if you aren’t allergic.
Many people react to mold by getting tired and even depressed.
Try to stay on top of moisture and mold as soon as either arises.
Dry out anything that is damp, such as basements (use a
dehumidifier) and carpets. Fix leaks in plumbing and roofs.
Wipe up spills. Make sure water doesn’t escape from shower
curtains. Vigilance will pay off!

Tea Tree Treasure
Nothing natural works for mold and mildew as well as this spray.
I’ve used it successfully on a moldy ceiling from a leaking roof,
on a musty bureau, a musty rug and a moldy shower curtain. Tea
tree oil is expensive, but a little goes a very long way. Note
that the smell of tea tree oil is very strong, but it will
dissipate in a few days.

2 teaspoons tea tree oil
2 cups water

Combine in a spray bottle, shake to blend, and spray on problem
areas. Do not rinse. Makes about 2 cups, lasts indefinitely.

Grapefruit Seed Extract
The advantage of using grapefruit seed extract instead of tea tree
oil for killing mold is that it is odorless.

20 drops grapefruit seed extract
2 cups water

Combine in a spray bottle, shake to blend, and spray on problem
areas. Do not rinse. Makes about 2 cups, lasts indefinitely.

Vinegar Spray
Straight vinegar reportedly kills 82 percent of mold. Pour
some white distilled vinegar straight into a spray bottle,
spray on the moldy area, and let set without rinsing if you
can put up with the smell. It will dissipate in a few hours.

In this country usually the bathroons and kitchens are facing the indoors...
I am from Brazil, and there all the bathroons and kitchens have a window... Most of them face the sun...
It helps a lot to kill mold and mildew...
I just do not get why here the houses have this setting... Why they are constructed this way...
It an paradise for mold and mildew...
That's why americans have so many breathing problems and allergies...

Aside from using vinegar for almost all my household cleaning and in my laundry, I also use it to get rid of the plaque buildup on dentures.Instead of using Polident Denture cleaner I use straight vinegar. Soak a few hours or overnight and brush off the softened plaque. Works great and it's cheap.

Barbara -

To get vinegar to stay up in the top of a bathroom drain pipe, first pour some baking soda down the drain. Then, when you add the vinegar, the baking soda will foam up to the top of the drain and stay there for a while.

You'll have to experiment with the quantity of baking soda and vinegar, but fortunately, both are inexpensive.

one of my ongoing problem areas is the bathroom sink drain. any suggestion for keeping a solution on the pipe long enough to kill the mold?

If U live on a concrete slab building, Your pipes are in attic,-sub floor spaces, as are your A/c condensation lines & drain trys. Plumbing Pipes-moves each time, faucets- valves are used, tiny leaks develope. A/c drain lines become mold clogged & the tray over flowes, Water travels to lowest level to exit. Attic's need to be well ventilated. & insulated, Insulation will hold gallons of water. This is dangerous place, to surch out a leak. Unless Ur a capiable DIY type, You need an experanced person & strong flash light. Water & electric are deadly- Elec. should be off, during hunt. apt/condo__call health dept & follow with certified letter, If manager does not fix. Send managers a certified letter also about your complaint, & health. Mold is not to mess with, seriously. Nothing you put on it well end problems; until leaks are fixed. Damaged sheetrock must be removed, Rotton wood & insulation replaced.
I'm not wishing YOU luck, as that will not do __ action is needed, & the sooner the better.

I live in an apartment that is driving me crazy. the mold is so bad that it has ruined a book shelf, blankets and is making me sick. I can see it on the walls at the floor. there are a few patches on the ceiling too. I use fans to try and keep it dry in here... The humidity is so bad in the apartment the windows are covered in water. When I asked the management to fix the problem they told me to put bleach on it! What should i do?

Tami, your problem may be a leaky roof! Mold likes warmth more than cold so the lack of heat probably kept it from being even worse. So why is so much mold growing in a cold attic, and from the ceiling down? It has to be moisture. Even if you don't see dripping leaks, moisture could be seeping through, especially if snow/ice/water are sitting on the roof. So long as there's that much dampness, the mold will keep coming back, too, so don't think just cleaning off the mold you have will solve the problem. Good luck!

i am kinda freaking out. i've had some strange allergies lately. thought it was an acquired seasonal thing. putting together that it may be mold. i work in an old building with mold issues. my old basement has mold. and i just found mold under my mattress. i'll try one of these methods and let you know how it goes.

Mold is killed by oxydation, the very best natural oxydizer is Hydrogen Peroxide, yet it is very safe. When Hydrogen Peroxide comes in contact with organic materials such as mold a natural burning process begins pure oxygen is relased that is more than the mold can handle and it dies. The wetting process is helpful because it keeps the mold from becoming airborne. Spray 50- 50 solution of 3% H2o2 let the mold die then use a wet vac to remove the mold.
