The WEB makes a lemon scented spray....other contractor only supply
companies offer various brands of this same type product.


That's great. Can you provide a link or more details. I haven't come
across that product before.


Believe it or not, Home Depot carries it.....
There is also another product by Purolator, called Facet.
Runs about $6 a can for the good stuff.

Will look for a link, or will post more in a few..


After following the OP thread that was started before, I would be leaning
toward regualr metal ducts, no insulation on the inside of them, and

thus,
prob has no need for anything other than fiberglass....



Why would anyone insulate the heat ducts inside a house. Any heat
loss is still within the house and therefore not actually lost until
the heat diffuses to outside the house. Ducting just helps the heat
reach the further parts of the house that would otherwise not get any,
as in heat from pot bellied stoves for example.


For starters, its part of the IMC, or International Mechanical Code.
Second, the OP in this case has her ducts in the crawlspace, and on a long
run, its possible due to velocity, size of duct, outdoor air temps, etc, to
lose a great deal of the heat that was originally sent down the line.
With AC ducts, without the insulation, you get sweating that will create its
own set of issues.
