OP Cleaning

I'm talking about "green" holistically speaking Steamer, i.e. from manufacture to the time it hits the carpet and has dried out, in other words it's total environmental footprint. If we are to look at it that way, technically encap is greener and Ripit yeah, lately we have had a lot of rain... problem was it was all in one hit, in one day, in about 30mins accompanied by hailstones that took out many a window, flooded houses everywhere, smashed cars to smithereens and nothing again since then!!

HWE is definately NOT 'green' but it does get more dirt out.

In that case I reckon a thorough pre vacuum with a Dyson ( or equivalent ), pre spray, rotary agitation, extraction with an emulsifier, rotary pad dry and acid rinse if needed can't be beat. ( with a petrol driven truckmount ). Whether or not all your customers are willing to pay for this level of service ( or indeed NEED it ) is another matter. Encapsulation has it's place but even it's manufacturers state it is intended as a maintenance clean NOT a restorative clean.

I say pretty much the same thing for the same reason.

I say "it will look alot better...than what it is now"

Ok now that we're settled down and actually communicating, I'm curious as to the conditions where you state that the stain "keeps coming back" if you HWE after OP cleaning. Having never had that happen to me I'd like to know under what circumstance it was that you've seen this.

Could it be an operator error - previous guy's, not yours? Or could it have been a chemistry issue - let's face it, some of the cleaning agents being sold out there are far from true encapsulants and make things worse rather than better! Could that have been the issue in your scenario? And what was the staining medium to start with? It's quite possible that the OP system effectively cleaned the face yarns, but obviously cannot draw through from below the primary and/or secondary backings of a tufted carpet. Hit it with moisture tho, especially at high pressure and particularly on a 100% polypropylene carpet, and you have the potential for migration of the original staining medium from the backing, as the top surfaces may possibly have been wet through right through to the backings. If you'd have OP'd it again you'd probably have been none the wiser, but HWE does have the potential to create such a problem.

So, was it OP not effectively cleaning, was it operator error, was it inferior cleaning agents or a combination of any one or all of the above...?

Blaming it all on OP not cleaning effectively is a long bow to draw, I'd like to draw on all evidence possible. Prove my thoughts wrong Steamer and I'll thank you cos I'll have learnt something, but if you are simply stating an opinion devoid of fact, then I'll challenge you to look at it further yourself.

Either way it's been a great debate so far lolz

I coined the phrase many years ago, "that you can NEVER totally clean a gravity fed medium".
