After some experimenting I have gone to the old fashioned household method of removing odors with backing soda and just applied this to the hose.
Make sure the hose is dry and that you dont do this directly after a smoke session.
Setup a teaspoon sized amount of baking soda on a flat surface and suck this through the hose with your mouth (without inhaling of course).
Let your house sit for a day out of moisture and in a dry area.
Get a vacuum, cup the nozzle, hold the mouthpiece while the vac is sucking
and do this for maybe a couple minutes to suck out all the powder
Hopes this works for others as well as it did for me getting rid of some Nakhla ghosting
