Quats really shouldn't be mixed with anything. I know a guy that mixed a deodorizer with an encap product and it created a rubber like seal through his SOLO pump up sprayer. It resembled that make your own gasket goop that shade tree mechanics use. The Solo was saved by clearing it out with a wire literally through the hose, connectors everywhere through the sprayer. It cleaned up easy, but it makes a guy wonder about whether encap chemicals will crystallize in the carpet if other products have been sprayed before or after.
