Cleaned it 10 times... PLEASE HELP!

I'm trying to clean some 5 year old nylon carpeting. Never been vacuumed or cleaned, has soil and tobacco on the pad, underneath. (Fine cut tobacco stomped through to the pad.) Using Rug Doctor, rug doc cleaners, oxy based spray, and Oxy Clean. Tried all combinations, and the carpet comes clean on top, but wicks up every time. A little lighter each time, but I don't want to keep this cleaner for 2 weeks.... Tried running over it quickly so not much water goes down, in an attempt to prevent wicking, but it always wicks a little, again and again. Also tried soaking the carpet with Oxy Clean, hoping it would neutralise whatever dirt was under the carpet. Still wicks.

Any suggestions would be greatly appreciated!

  Good one Ninja-wand

First of all...........the machine your using is not powerful enough to suck up all the water you are putting down.......thus wicking will occur........as for the chemicals you are using........better use a fiber rinse to neutralize. If it was possible for you to rent an OP machine it would sure help........but there's not much chance at that.  If you are a home owner.......suggest you get the big guns in to solve your problem.

Sorry, I wasn't clear. The carpet comes clean on every pass. The problem is wicking.

The exception would be the tobacco stained area in one room. It is somewhat darker than the rest of the carpet. Any specific recommendations for the tobacco stain?

Hell just cut it up roll it and smoke it?

Thanks for the fast and helpful replies everyone! I'll get a couple estimates before I go any further.
