I completely clean every pipe after every use, which means using 91% Isopropyl, pipe cleaners, and dry reaming the bowl. That way I never have to worry about ghosting or sour pipes. I’ve done this for over 50 years with no problems.
Cool thank you. Same steps to cleaning with salt and stuff like here:Isopropyl alcohol is what you want. I use 99%. Far less water content than booze, unless you can get your hands on pure !00% grain alcohol, but I have never seen it. It is not poison (at least anymore than any other alcohol) - they use it to clean open wounds. I understand that in some countries it is "denatured" - which simply means they add something to make you sick otherwise whines would be buying it to drink.
EVERCLEAR is 151 proof (75.5% grain alcohol) taxed for consumption & available at liquor stores.
Here too but I found it too expensive for estate cleanings and now I go with 91% iso.Here it's 190 proof.
