Tallow Soap a stain remover?

Can tallow soap tackle stains? I was at a farmers market, and a customer asked if my soap could remove stains. I'd never thought about it before. After that chat, I was super curious and couldn't wait to get home to give it a shot! Luckily, I had just the thing to test it on – my husband's work jeans!

First, I got my solid tallow dish soap wet and started scrubbing the stains. It took a few minutes because they were pretty big. After that, I washed them with my tallow laundry soap.

and just like that, the stains were gone!
