    Cleaning LPG from small orifices is very hard and replacement is
    probably the most effect solution. In other industries our company
    serves, the answer to LPG contamination is a green scrubee and elbow
    grease - something that obviously is impractical in this case.There
    aren't any effective solvents that we know of, just plain friction. 

    There is the alternative of switching to high-pressure natural gas
    for torchwork. Natural gas is never in liquid form and so this kind
    of problem can't occur. It is possible to get high-pressure natural
    gas safely, without going through the gas utility, by using a natural
    gas Torch Booster. At sufficient pressure, about 20 psi, natural gas
    is even effective for casting a high temperature metal like platinum.
