Side and rear catalytic liner kit, suits electric ovens which have removable shelf supports. The Catalytic Liners trigger an oxidation process which turns the grease and grime which is trapped in the porous enamel into tiny dust like particles. These dust particles can be easily swept or wiped out of the oven, after the oven has cooled down. This means the oven can be cleaned without the use of harmful chemicals. It also reduces the amount of time typically taken to clean an oven, giving you more time to spend with your family and friends. The Catalytic Liners are coated with porous enamel which absorbs grease and grime within the oven. This grease and grime is oxidised when the oven is heated to 220 degrees Celsius.
