3 Ways to Kill Mold Naturally

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.

20 Great Uses for Tea Tree Oil

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. If you don’t like the smell of vinegar, you can add essential oils for a more mellow scent.

I forgot to add that when cleaning mold use a mask and rubber gloves with no holes. I use a 50/50 white vinegar wash it off with the mold and then leave on a full strength coat and let it dry---the acid in the vinegar will help slow the regrowth of the mold.
When I moved here and got infested no medical test showed the mold in my blood tests, just that something was very wrong & now I can go into a store and have a headache in 15 minutes if there is mold some place {like the back room} so I just stay away, shop once a month and that's it for me.

NEVER use BLEACH for mold! The Red Cross online said depending on the type of mold it can create an invisible gas that will permanently scar your lungs the very first time you use & you won't feel a thing. Mold causes serious daily headaches even if it's growing some place you can't see it like behind walls, in the corner under your toilet----it can and will infest every organ in the body and in the end kills people here in almost got me until the online Red Cross nurse called me back and explained it-----had to say good bye to my house, now saving money to move back to Ca...I know mold is everywhere but not as pervasive as Oregon. Many babies die of black mold as it grows inside their lungs and no one notices til it's too late..

I add essential oils including tea tree to vodka in a spray bottle and it works nicely on things. Not going to do that now for the sake of the critters so it will be other oils once I research and find which are safe for them.

Should anyone reading this get cold sores tea tree oil works a treat. Got my first one last year because all the other "joys" about aging are so much bloody fun I guess it was to keep me humble. le sigh

Tea tree oil is a neurotoxin to pets, I didn't know this until it was mentioned here. Thank goodness for vinegar, I found extra strength cleaning vinegar recently. It's strong but works very well.
