A method for cleaning an exhaust stack tube of an oil tank heater comprises the steps of securing collection drums at open ends of a heater tube using attaching straps; securing a drop cloth over an exhaust end of the heater tube with an attaching strap; interconnecting the collection drums to one of a vacuum apparatus and a receptacle container; attaching a nozzle to an end of a high pressure hose; inserting the nozzle under the drop cloth and into an exhaust end of the heater tube; forcing wash water under pressure through the nozzle; guiding the nozzle to the top of the exhaust stack; pulling the nozzle back a few feet and, again, guiding the nozzle upward while rotating the nozzle; and repeating this process until the nozzle reaches the bottom of the exhaust stack.
