Hi. Usually after I have my clay already hydrated to a pudding like mixture, I take about two cups of that and enough hot water to fill up a plastic dish pan to soak my feet in. I mix it in really well with the water, and then stick my feet in it for about an hour. It doesn't have to stick to your feet or anything, mine ususally just looks like slightly thick greenish/greyish water. I let it sit over night after i am done and then I pour off the top water outside in the yard and check out what is left in the bottom! You will be amazed--hope this helps.
