I am assuming, by heavy ends, Robbo must mean any build up of flammable residue that may be in the cylinder. Propane, Butane and other "anes" like methane, heptane etc etc are whats known as light ends in the refining industry and will contain a minute amount of heavy ends such as naptha or gas oil. thats why the cutting when its full of water is the best option.
Of course I could be barking up the wrong tree completely!!
