Everyone is right kind of:-
Looks nice and clean to me. But seen it before.
But 1 prob that appears to me is that your operator has set the pile on the arms by pulling the hand tool towards him.
Thereby giving the appearance you have there, it looks different, there is a perceived difference in appearance.
The pile (or nap) on brushed upholstery has to 'fall' down the seat, cushions and arms, I think you will find that if you go back and rinse it again with warm water and reset the pile with an upholstery brush or clean cloth on all of the chair so that it is in a uniform pattern it will give a much better overall appearance.
Hope that helps.

Arm cleaned and reset at the time and have been back sprayed down and reset the pile it just when back this way when dry but you can brush it the other way just it like laying this way !
Could it be pile distortion due to excess heat? The shaded areas seem to be where you would expect there to be more work.
or perhaps where you would expect there to be more wear? temp was constant 60c beside you would really expect to see a problem on the set pads and other elsewhere as well?
looks like pile distortion to me. did you set the pile after the cleaning process.
yes but if it was shading there before, it may well come back would you agree? I know we try and steam it out of some carpets and curtains for manufactures but it is a inexact science and often does'nt work.

The picture and your description suggests a synthetic pile and cotton backing. If the fabric has just been cleaned, it is possible that the cotton backing, if not soiled, will have absorbed some moisture and be showing darker in the local areas that have required more work. Upon drying, these damp areas dry fine, so no problem.
When dry, if staining/soiling does exist and is not an optical illusion because of light reflection characteristics, I have in the past tackled this by cleaning again, but after the pre-spray used an Oxybrite/Fibre Buff/Shampoo solution applying the foam by sponge and then rinsing with Fibre & Fabric Rinse. This is an extreme course of action as an soiling that may be present would typically respond to conventional cleaning.
Safe and happy cleaning

it is just that a optial illusion did the mirrior test for shading and bingo there it was in the reflection all gone! The problem is just that shading.
Without seeing how the chair looked before cleaning difficult to say.It looks clean.What exactly has she accused you of?
We are accused of "totally ruined can't say exactly just ruined! the colours have run and is ruined"
Steve It looked very similar to it does now just more dirty! ( it's on your patch as well so you might get a call from me to get a 4th opinion)
Plain and simple,
I think all of you guess it.
Its shading, told the customer that and explained how why ect, and think they took it on board.
Reason for posting is today we just had Johnny splash and dash on the phone, his mums, aunties, friends, dog sitter, that lives across the way. And he reckons we have made the dye bleed on all the suite and took it off in parts, and it's a "total write off" Best just pay up the 3K or we are going to court and we'll lose because he'll be a witness. And the Solicitors letters in the post.
And someone rang from the ladies number to get our postal address? would not give her name, and said I'll find it anyway. we did give her it just asked "can i ask who is calling"
Reckon i should get my cheque book out?
