Use it at 1:120 for most jobs, 1:100 if they're a bit minging, 1:80 for salvage work, care homes, odour problems etc.
Spray up liberally, but obviously within parameters of what the carpet can stand. Brush in with groomer on most domestics (axminster, 80/20, most tufted types etc), always use mechanical agitation on commercials.
Sometimes use bonnet for agitation and initial cleaning followed by extraction.
Leave as long a dwell as you can, sometimes I go up to 30-45 mins on big jobs. No, it doesn't mean you're sitting in the van looking at your watch, as Chris says just work ahead with your prep work. Obviously the carpet is going to feel like it's dried out in some cases but the product will still be working and you can keep it topped up a little.
Working in bigger areas also actually makes up a bit of time as you have to turn the machine on and off less times and extract more in one go. This is especially true in empty houses, you can do them in 2 sections, upstairs & down
On smaller jobs, mechanical agitation makes up for less dwell time.
Cold water rinse is fine in most cases, I still crank it up to bloody hot for filthy carpets, partly because I think it does mobilise certain soils better and also because some of my problem solvers work better with hot rinse.
I honestly don't know where people get the idea that it doesn't work on synthetics as well as wool. Well, I do know, it's because one person said it and then everyone else copies them, but that's forums for you :
I've found it excellent on all fibre types. The jobs that don't turn out looking a million dollars are normally due to the way in which they got so trashed in the first place. Brown things and polish spring to mind.
You only need to rinse with fresh water. Advantages are obviously no extra expense on rinse agents, and as Fintan points out you're preserving your pump (presuming you're using a portable).
Diamond how much of a free sample did you get? You need to take it out on a good few different jobs, just using it once or twice is useless. It also helps if you've got a pressure-free job or two where you're not under pressure and have time to play around a bit. Your own carpets or friends/family may be the best bet. I used a commercial building that I work in, had all day to do a few rooms and the place to myself...so I took advantage of the situation!
Shaun, I think the weather has been splendid
"Most" use pureclean? Never heard of that before, maybe david j jones knows different, i think his cousin has registered on here now, see if he'll ask him
