Carbon deposits and oil residue can foul the tiny apertures in fuel oil nozzles and interfere with their proper functioning. Ultrasonic Cleaning Systems from L&R can restore their usefulness.



  • Disassemble nozzles, place parts into Basket.
  • Place Basket into half-full Auxiliary Pan containing L&R Hydro-Sonic Cleaning Solution Concentrate or Hydro-Sonic Cleaning Solution Concentrate Non-Ammoniated, diluted 1:7 parts water. Agitate or swish tray up and down to remove excess oil.
  • Remove tray -- drain.
  • Place into main tank containing the same dilution of Hydro-Sonic or Hydro-Sonic Non-Ammoniated Cleaning Solution Concentrate and cavitate for 20 minutes.
  • Remove and rinse with hot running water.
  • Dry and reassemble. (Dip in fuel oil for storage.)

Note: Clean only one tray at a time. DO NOT OVERLOAD. Change solution every 6-8 trays. Plastic nozzles can be cleaned the same way.
