CRB brushes

[encaprodney]

For HWE, Encap Punch would be a good choice of chemical since it designed for that purpose. You could also choose Encap Hydrox if you are dealing with organic/protein based soiling.
As far as procedure... you could first put the renovator trays on your CRB for great pile lifting/dry soil extraction, prespray your Encap, then scrub with your CRB and extract. Using that multistep process will really get the most out of your cleaning!
