Customer allergic to cat dander

[Stan A]

I have a customer who told me how her eyes swelled after being in there to be new home after a couple of hours. Said the previous owner had the carpets steam cleaned. Long story short, I have one of Ricks crb machines. I run the crb first and follow with pads on one if my o.p machines and either follow up with a good crb again with trays again to groom and pick up more gunk or a good vacuuming. Question is will this help with her allergy problem or will I need a special chem? Thanks
