Hi RIck,
I'm too tall to get by with the name Shorty but I'll throw in my 2cents worth.
We don't get Stain majic for wool here so not too sure of the active ingredient. I would recommend H202 as a start.
Be very careful that you have a clean carpet first. Rinsed and neutralised preferably to the acid side. Using a recognised acid rinse should take care of that for you.
The reason I say that is because I've had a few wools where the protien has been striped out with H202 when its gone over something else the client has put on it before I got there and so I've ended up with a slimy mess that is very difficult to correct and impossible to replace the protien once its gone.
I you're concerned in any way, start at 3% and work up to 6%. If you can find a good A%B mix then go for that.
I know Prochem has just put one out downunder called Stain Rescue.
Be careful heating it though, I'd rather do an overnight treatment even with something on it to slow down the drying and prolong the activity. That would be better than doing a short heat test... apart from having the urine activated for you and her to smell
Wool can withstand longer periods of heat than the synthetics... you can put your iron on a low/delicates setting and with a one-two layers of terry towelling dry can go up to 40 seconds. Start at 20, rinse, reapply 30, rinse, reapply 40 etc you get my drift.
Obviously, being a natural fibre, be aware of chemical sensitivity. From both your treatments and also the urine itself.
Remember that the urine dries and the alkalai salts can cause permanent and irreversable damage to wool. Do your tests, BEFORE you promise anything. You've already established credibility with the client with your burn test. Don't undo that!!! Explain some of these problems from the point of view that the problem is already there because of the urine and you want to do a few tests to see if it too late to reverse it. Drop by and do your tests and leave it for 24-48 hours and then personally go back and see for your self. That way you can tell her exactly what she san expect if she wants to go further.
Depending on what she as a client means to your business will determine if you charge her or not. Also you may consider repairs???? Only you can decide if thats right given all necessary criteria.
Ok thats possibly a bit long for 2c maybe try 4cents
