My son sent me a Persian carpet from Iraq- my dog puked on it - I
tried mild soap and water - and it did not work - any suggestions on
how to clean it?

If where you live there are any dealers specializing in oriental rugs,
they might be able to clean the rug for you. There's also an
orgazination, "The National Institute of Rug Cleaners"--certified
specialists in cleaning carpets--and you can look for a specialist
near you through http://www.ascr.org/institutes/findamember.cfm?institute=nirc

Hi!
I have a very large breed dog who has been a little "challenged" with
potty training and accidents.  I also have an antique rug, in shades
of white no less, which the dog defacated and vomited right in the
center of.  After 3 weeks of research and trial and error spot
testing, I finally came upon a dry carpet cleaner made by Oreck.  My
main problem with the wet cleaners is that it made me nervous to
destroy the fibers.  If you have an Oreck store near where you live,
or you can go online, take a look at the Oreck dry carpet cleaner, and
the No Return cleaner---I'm totally addicted to it to clean carpets,
rugs and upholstry.  If you also have stains on the carpet, you can
rent an orbiter to make the process less work for large areas, but for
a small stain, I don't think it's necessary.  If you have any
questions about the system, just let me know and I'll tell you
everything I can about my experiences with it, as sometimes asking the
Oreck people turns into a bit of an infomercial.
Hope this helps!
