Easy-Off is one of the more popular brands of oven cleaners. You can use Easy-Off to clean your convection oven. In fact, it isn't much different than cleaning a regular oven, besides a few key points. Follow the recommend procedures and safety measures when cleaning your convection oven with any type of oven cleaner.
Make sure your oven is completely cool. If it's still hot, let it cool off for at least an hour prior to beginning.
Remove your racks and set them aside. Liberally spray the Easy-Off Oven Cleaner on the oven floor and walls. Do not spray it directly into your convection oven fan.
Let the oven sit undisturbed for several hours--overnight if possible. The longer the cleaner sits, the more effective it will be.
Wipe down the interior of the oven thoroughly with a soft, damp sponge and a hand towel. Make sure the oven cleaner residue is completely gone.
