"Clean" your body? Isn't that what soap is for?
If you're a reader, get YOU: An Owner's Manual, and if you're not, watch Dr. Oz. He's sensible, talks about well-researched and convincing alteranative medical practices, and basic healthcare in very easy-to-understand ways.
There is no supplement --at any cost-- that will compensate for inhaling and swallowing toxins. Don't shop for something to compensate for it, stop doing the damage. When you stop, your body will slowly be able to deal with the buildup, everywhere but in your liver (which stores toxins the body can't deal with, and there is no way short of a transplant that will remove them).
Eat real, simple, fresh food. If you don't know what trisodium phosphate is but you do know what an apple is, chances are excellent that you should be eating only one. Use that as a label-reading criteria: if you can't buy it at a grocery store, it's prob'ly not food, yeah?
