Using Borax around the home

I always thought borax to be an extremely toxic man-made chemical, best avoided – but it turns out it’s a naturally occurring substance with many uses. It’s cheap and relatively environmentally friendly when handled with the proper care (i.e. don’t eat the stuff and keep out of reach of pets and children) and used minimally.

Borax, also known as sodium borate or sodium tetraborate, occurs naturally and is mined in the Mojave Desert (Boron, California), other US states, in Chile and Tibet. It can also be created synthetically from other boron compounds. The mining side of borax production isn’t all that earth friendly, but compared to some other chemical compounds used around the home, it’s likely lesser of the many other evils, so it’s a “greener” choice.

Borax used in all sorts of products – pesticides, insulation, makeup, detergents and other cleaners. In our house we have recycled cellulose fiber for roof insulation that’s been treated with Borax in order to make it flame retardant. The other side effect of this treatment is that it discourages vermin from nesting and kills insects.

Handy Borax tips

Warning – as mentioned in the start of this article; it’s *relatively* safe to use. Given it’s insecticidal properties, that indicates that it does have some level of toxicity and should therefore be treated with care. Ingesting Borax is certainly not recommended, although in some countries it’s used in foods in small quantities as a replacement for salt. Given that it does have some toxic properties, I was very surprised to find it used as a food additive and in makeup. It’s always advisable to wear gloves when handling borax as it can cause skin irritation for some people. Borax should also not be inhaled.

I was reminded today that sometimes we forget that simple water and a bit of extra elbow grease is all that’s often needed for cleaning. When that’s not enough, substances such as baking soda and borax are effective “greener” cleaning solutions than many of the other products available commercially today.
