Im a little confused

,
I had a call from a custy asking me if I could remove a red wine spill from an expensive wool rug,
My reply was I would visit, and tell her the possible results and the possibility of the stain not been removed completly.
I was then told over the phone , " you will get it out using Red rx " !!!!!!!!!!! bit surprised, hearing this info from a custy

after explaing it was not quite as simple as that, I asked where she had got this info from. her reply .
Another local c/c , had told her , even to the point of where to buy red rx , and it would be far cheaper than him coming out . I would suggest more likely didnt fancy the task
However a couple of points niggled me,
Why on earth would a c/c pro suggest a product like red rx to a potentialy damaging situation, and secondly if the custy indeed had of gone ahead with the c/c suggestons , would their have been any come back on the c/c giving out the info?
