Re: Thickening of carpet fiber strands after a service (fuzzy expanded strands)
If you come across a Frieze and you want to be safe use more pre-spray, wetter Gladiator Pad, thickest glider and move quickly. The post vac will be return the twist back in the yarn as well.
You can always use synthetic pad like a Tuway Pad if you're really nervous. If you really don't want to chance it buy a portable. Personally I have never had a complaint.

Dave get yourself some glads at CCS, http://ccsop.com.
Cotton pads are too aggressive for that style of carpet. I use Glads for everything except berber and CGD. I use a fiber plus pad on those followed by cotton pads.
The solution you used was fine. Pads, not so good. Even with a Glad, you'd still want to keep it very wet on that carpet.
