From cooking hot dogs and other small foods to toasting breads, roller grills are self-contained cooking appliances that contain a drip pan and a motorized drive gear that moves the food through the cooking element. It is important to clean roller grills regularly to keep crumbs, dirt and grime from building up on the rollers and other internal parts. To clean a roller grill, you don't need special products, and you don't need to disassemble the appliance.
Turn off the roller grill and unplug it. Let the grill cool if it's still warm.
Wipe the entire appliance with a soft rag or towel to remove any loose crumbs and dirt from the grill and its rollers.
Remove the drip pan from the roller grill by pulling the pan from the bottom of the appliance.
Fill a sink with a 1/2 cup of mild dishwashing detergent and warm water. Wear latex gloves to keep your hands from getting wet.
Use a sponge to wash the dip pan in the soapy water. Rinse the drip pan with hot water.
Mix 1/2 cup of mild dishwashing detergent and 1/2 gallon of warm water in a bucket.
Dip a soft rag or towel in the bucket of soap solution. Wring out excess soap solution.
Scrub the roller's casing, inside and out, with the soap solution-soaked rag or towel.
Apply a tbsp. of a household abrasive cleaner to a scouring pad, if stubborn stains remain on the grill. Scrub the stains with the abrasive-soaked scouring pad in the direction of the grill's grain.
Continue cleaning the roller grill with the soap solution-soaked rag or towel or a scouring pad until the grill is clean.
Dry the roller grill and drip pan with a clean rag or towel.
Place the drip pan back into the roller grill.
