In reference to cleaning your hoses I like the clarenet idea I
would pass a cord long enough to be at least double the length of the
hose then knot in the middle a swab of cheese cloth( or other lint
free fabric) and start with a dish soap / hot water , then plain
water then finally dry swabs top remove any possible contamination by
pulling the swabs back and forth, much as a rifle user will clean the
barrel. If the hoses are short enough and you have access to a rifle
cleaning kit you could use that.
In reference to the Torch You have a few choices.
1- Return it to the manufacturer for cleaning and a rebuild.
Expensive but sure, and will take time.
2- Go to an electronics supply store and buy a can of Electronic
cleaner and a can of compressed air. You want the Freon type, not
the type that contains lubricants. I would then (while wearing safety
glasses) use the cleaner to clean out all internal passages and
valves in the torch. Once you are satisfied that the passages are
clean flush and dry them with the canned air.
3- Dish Soap and hot water followed by clear water, then dry with
canned air (note you can get canned air at photographic stores as
For the regulator I would only go with option 1 or 2 above or
replace it altogether.
For the tank I would replace it Period.
General comment #1: for Fuel hose (Propane or bottle gas) almost any
cleaning method (except using compressed Oxygen that is) is safe.
For cleaning a hose carrying Oxygen never use a petroleum based or
flammable solvent as it is almost impossible to remove every trace.
For a compressed air hose almost any method will do.
General comment #2: If you just want to blow it out with clean
compressed air, go to a place where they paint cars. They will have a
compressed air setup with both oil and water filters so has to yield
pure compressed air, as any contaminant would ruin a paint job.
General Comment #3: If you call around to places that supply
Acetylene and Oxygen to garages etc. they will be able to refer you
to a place that repairs Regulators and torches for the trade. They
will have the tools and Knowledge to fully repair and recondition
your torch, Regulator and Hoses.
General comment #4: Grin if your LPG supplier so cheerfully says
can't be repaired buy new, send them a nasty letter (in full legal
form of course) holding them responsible for the damages and asking
them to replace the equipment as they were the source of the damage
and thus in breach of contract to supply pure bottled gas and it is
their recommendation that the equipment should be replaced.
Hope this helps and if you have any questions feel free to contact
