A common question we get asked is "What's the difference between boric acid and borax?"
To be honest, there's not a lot of difference between the two products and they're easily confused. If you placed them side by side, you wouldn't be able to tell the difference.
They're that similar they're interchangeable in almost every use. On the surface you wonder why there are two products so similar on the market.
But by looking into the areas where they are not interchangeable, the differences start to become clear.
