I used a syringe to repeatedly inject a water+detergent solution beneath the tape, between the tape and the metal venting over the length of the pipe while I continually sprayed the outside of the tape with a spritzer bottle. Stuff came off easily.
Oh yeah, I wore a mask, gloves, old clothes, and double bagged everything to take to the HAZMAT disposal site.
I have the same duct work problem. I am sending a sample to 'Pro-Lab' to verify the suspected asbestos. MIOSHA (Michigan OSHO) said it is best encapsulated rather than disturbed/removed. They also claimed that, if undisturbed, friable asbestos would not enter into the duct and even claimed the ducts could be professionally cleaned--contrary to what a duct cleaning service believed.
Given it is controlled by water & water mist, I'm wondering if a dehumidifier will help remove it from the air...and dumped down the drain. I assume it can be removed from the water supply...perhaps a better ideal is to pour into a hole in the yard and then covered with dirt? Asbestos will likely also be present in the dehumidifier filter...dispose and replace often.
