This may be a stupid question but here it is anyway. From what I understand when you are using encapsulation cleaning you leave it in the carpet to do its work therefore leaving the dirt in the carpet also. So here's the question why not clean with an encap juice, then thoroughly extract the carpet, from what I understand your bound to leave at least a little residue in the carpet which would let the encap work its magic and also you'd be able to remove the dirt therefore producing great results? Take it easy on me now, I just want to understand encapsulation cleaning a little better.
