Charging for deodorizer with vlm process

[mark63]

I like to offer and charge for stain protection and deodorizer. I was wondering how you apply a general deodorizer with a vlm cleaning process that wont mess with the drying process?
Also, since im on the vlm pro board, is there a encap solution for residential cpt that does not leave the carpet crunchy? I know oxi fresh advertises your cpt wont be stiff after the cleaning. Thanks!
