"I recently had new garage started to be built. since the weather here in Indiana is so cold., due to the late start, my contractor. discovered it was colder then he thought it was going to be. he became sick which left me with numerous little jobs to do and I brought out my trusted salamander heater. so while installing insulation to the inside of my new garage I would fill the heater and use it to make the tempter bearable to work in . Then while working one day the salamander heater would run for a few minutes and then stop. Over and over again I would restart the heater, and it occurred to me this thing works like a jet engine or a carb on a auto engine. I wonder if the jet is clogged up or something else is in the fuel causing this problem. so I had just purchased some of your cleaners for my truck and car as I often do and add it in occasional.. I retrieved the cleaner quart bottle and poured some into the salamander tank. then picked the heater up and shook it back and forth several times. I plugged in the electricity and it started up heating. I noticed the flame seemed brighter and the heat was notability better. soon it was sounding like a solid burning unit. I was a jet engine mechanic in the USAF and I listen to the engine and you can tell when it burns well or not. since that day the heater is working very well and no more shut downs due to what had caused the problem originally. You could advise more of your customers of this little trick to remove any carbon build up on the salamander injectors or the fuel pump, or just deicing the fuel tank. so thank you for all the help. Oh by the way the contractor had the flu and is still healing . I am still doing little things to the inside of my new garage. and the heater is running everyday top notch. "No new salamander required, just a little Lucas injector cleaner." Thank You." -John D Hughes
