I love Evaporust!

I do like it and I've used it a good bit, but so far, I've not figured out how to keep it from losing its strength and it loses it pretty quickly. I've tried straining it too. I'm beginning to wonder if maybe I got a bad batch.
I've noticed I can make it last a little longer if I thoroughly clean and degrease what ever I'm soaking.

As it evaporates, you can add water to it to bring the volume of fluid back up too but I've had good luck using it in sealed containers or tins pans covered with foil, etc..
