I have been maybe lucky.. that 3 times tried it its made a marked difference every time.
more than one treatment may be required for very heavily clogged.. you then at that point have a decision to try again or remove and clean it by removing it etc..
its worth a punt as a non invasive product which requires no skills or tools to administer.. and build the treatment into the service schedule will keep things clean.
