Maintenance; Cleaning The Oven - Marshal MB42 Installation & Operating Manual

OVEN EXTERIOR
The stainless steel surface should be cleaned when cool using a mild soap and warm water
solution on a sponge or a clean cloth. On WF Ovens, clean the glass only when the oven is cool.
OVEN INTERIOR
The inside metal surfaces should be cleaned with a mild detergent and a damp cloth when
necessary. The brick surface should be brushed clean and then a wet cloth draped over the
brush should be run over the surface while the oven is still hot.
NOTE: The burner venturi must be checked and kept clean. The area around the air shutter
must stay about 1/8" - 3/16" open and free of any dust.
On the stainless steel front the deposits of baked splatter may be removed with any nontoxic
industrial stainless steel cleaner. Heat tint and heavy discoloration may be removed with any
non-toxic commercial oven cleaner.
1. Apply cleaners when the oven is cold, and always rub with the grain of the metal.
Clean the aluminized interior portion of the oven with a mild detergent. DO NOT use caustic
solutions such as ammonia, lye or soda ash. DO NOT use domestic oven cleaners. Any of these
products will damage the aluminum coating.
DAILY CLEANING
• Clean brick surfaces using a deck scraper and brush. A wet towel draped over the brush
should be run over the brick surface while the baking chamber is still hot.
WEEKLY CLEANING
• Brush out the combustion compartment behind the burner door.
6 MONTH CLEANING
• Clean secondary air ducts and air entry ports.
• Clean the area around the air shutter so that it stays 1/8" - 3/16" open and free of dust.
CAUTION: Disconnect the power supply on MB Ovens before Cleaning or Servicing.
If maintenance or repairs are required, contact the factory, the factory representative or a local
Marsal service company.
