The Hunt-dri concentrate is mixed with water, clothing soaked, then wrung out, I then put it in the washer on spin only and collect the liguid from the drain hose for reuse. I tried the spray once, on a pair of cordura boots, it works but the concentrate costs less, I think it could be used in a spray bottle for something like boots that you wouldn't want to spin in the washer, but best of all, there's no odor after it's dry.

Supposedly Walmart carries it now, but I've not seen it in mine yet.
