I'm not sure there is any such thing as 'double strength PB,' you can put as many spoons as you like in the mix but it doesn't make it any stronger. Adding something like Citra boost may well produce the desired result by making it deal with a wider range of soils.
Also, soil sometimes comes off in layers and multiple applications of a pre-spray may well be the answer rather than trying to flood it out in one go.

ahhhhhhhh citra boost  wouldnt be with out it 

[Kriss]

you have done the job right now thats all that matters at the end of the day , ive been cleaning carpets for over 25 years and still picking up little tips

 we have all had jobs like this where we have had to go back to them , and if anybody tells you they havent then there full of bull    you can have all the training in the world but you never make a cleaner until you been out there and got down and dirty its that simple

i am sure next time you come across this you will wip it clean in a jiffy its all about learning my friend 

That is true  We learn a liftime Thank you Susan ;-)

I will take a notice of that and try take it off in layers next time. Hopefully wont get so many of those carpets :-)
Thank you Simon

This came off in layers 

[Kriss]

I bet, you have not used 135 psi  sensei for it?

This came off in layers 

Jim, that one looks like a Damien Hirst!

Kriss,
Whether soil comes of in layers (or with successive attempts) or not it does give you a sense of whether your chosen chemical is doing the job. You could find with a second attempt that it is removing all but one  type of soil, so you then go after that with the same, or a different chemical depending on what you think the soil is. You will then reach a point of either perfection, or the best it is going to get and that is when you know when to stop and if the result is less than perfect you can hand on heart say you've done your best.

Good point Simon. I will have to invest in some more different chemicals. Thank you for all advice. It is very important for all of us, and especially for new starters like me

[Jim_77]

Ian, even Damien Hirst wouldn't touch that with his bare hands 

Kriss, you might be surprised to know I was rinsing at only 200psi on that job, but the water was coming out at 240F and getting sucked back with 14"Hg and ~400CFM of air movement

I think if I'd attempted it with a sensei I'd still be there now

Simon makes a very good point about soil types and different chemicals.  However I think that the "heavy duty" chemicals we have at our disposal today are so good across such a broad spectrum of soil situations that it's very rare indeed that one will out-perform another to a noticeable level.

Thanks Jim

hopefully, next time i will be able to upload some better pics and be more satisfied from what i do
