B. Cleaning Conveyor Ovens

  1. Disconnect power to the oven before starting the cleaning process.

  3. Scrub each section of the conveyor system with a degreaser and brush, paying special attention to grease traps.
  4. Wipe down the interior surfaces and walls with a damp cloth.
  5. Reassemble the conveyor after confirming all surfaces are clean and dry.

C. Cleaning Wood-Fired Ovens

  1. Ensure the oven is completely cold before you begin cleaning.
