Borax is known for its uses in the home as a boost to washing clothes and even for pest elimination, but there are so much more Borax uses that you probably don’t know about!
Borax is known as sodium borate, sodium tetraborate, or disodium tetraborate. It is a naturally occurring mineral found in soil, plants and even within our own bodies. It is an important boron compound, a mineral, and a salt of boric acid. Powdered borax is white soft, colorless crystals that dissolve easily in water.
Most borax comes from a mine in Boron, California, which is the largest, most economically sound, and environmentally sustainable mine in the United States. The product of Mule Team 20 comes from this mine.
Some people ask if it is safe. Borax is considered a non-carcinogenic and a mild skin irritant. It is comparable to salt and actually, ounce for ounce, salt, is more toxic. Like salt, a little is good for you but a lot can kill you. So you make the decision.

is the borax /water mixture for weed killer toxic to pets?
Hello Carol
I think that Borax is absolutely toxic to pets! I would not recommend putting it where they can ingest in it any way.
Pour a 1/2 cup of Borax into the white wash and watch the dingy yellow ( be gone )
Love that tip thanks!!
I didn’t really know what borax is actually for until I read this. Thank you for the good tips!
Well, I learned some new things from reading this!
I’ve bought borax before for specific projects, then have wondered what to do with the rest of the box.
I’m going to try the tip of using borax to deodorize the kitty litter box. Hope that works very well, since we have four cats.
Thanks for sharing on the Homestead Blog Hop!
Glad it could help you! And thanks for taking the time to read my post!
My granite countertop in MBR bath does not “seal”. With eczema, I use a lot of oils. The area right in front of bowl has darkened. I have tried steam iron with absorbing towel. The installer tried baking soda and peroxide with plastic wrap for 24 hours. Help! There must be something that draws out the oil.
Cornstarch absorbs oil. Not sure if it would work on granite, but worth a try. Good luck!
