3 Ways to Kill Mold Naturally

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.

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!

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.
