At the end of the day people expect us to get results and are willing to pay for that. It is your choice, you can learn to meet peoples expectations or you can lecture them on the subject and let somebody else take the customer. Customers who have been told by competitors how things can not be done tend to become loyal and good sources of business once you prove the others wrong.
I have renovated rugs with bleach 20 years ago that are still in use now, any argument about bleach being corrosive etc is just rubbish,
I have done what the customer required!

Peter,
Bleach does dissolve wool - we use it all of the time as part of the fiber test to identify wool from other fibers. Watch for yourself, drop a strand of wool in a cup of Chlorox (chlorine bleach) - and it will bubble and slowly go away.
Now, it's not going to make a big hole in a rug (I've dumped straight Chlorox on a rug in a class to show them what it does and does not do)... and it can help strip out colors to make stains less apparent - but under the microscope, you ARE damaging those fibers.
I've used stripping agents and bleaches on rugs - but always with permission from the clients and acknowledgement that this is causing structural damage for the sake of better appearance, and have them okay that.
With Chinese rugs, which have already been heavily chemically washed with a chlorine mix before even being sold, these ones tend to be much, MUCH more sensitive. If the urine stains were on an India rug, I'd play with bleach, with a Chinese wool 90-line rug - nope. That very stark dark and light direction, due to that chemical processing, and showing every mark I make on that field to improve the stained area, it's tough to hide your work... like working with velvet almost, you see those strokes.
That said...posting on a forum "hey just use some bleach" is dangerous advice. You may have experience with it, but I handle a lot of technical help with carpet cleaners who take their "spray it up" skills that work fine on installed carpet, that can lead to disasters on rugs.
So... perhaps you could ask for photos to be posted, and share your step by step "how to" for this particular cleaner, and he can see if he has a master hand at it as you do.
With Chinese new product from 1980s on - I don't mess with them. They are already structurally damaged from the chemical washing they had in China.
Thanks,
Lisa
