Don't worry Jamie, we aren't it is Surround Revive it we are getting.
Simon the new Polymer Encaps work in a different way to crystallising shampoos and microsplitters.
The residues remaining from shampoos and microsplitters are just dry residues of the product and dirt. This residue can easily be re-distributed within the carpet due to moisture, spillages or wet feet.
Polymer based encaps encapsulate the dirt and the carpet fibres leaving a very thin coating on the fibres, a third of the thickness of a human hair. Once any residues dry they are completely innert as they are a plastic so can't be re-constituted with water.
John Klucznik posted some very interesting electron microscope photo graphs on the US truckmount forum.
