Oven protection spray.
This is a specially formulated product for Rapid Cook ovens, Rotisseries, and normal ovens.
The spray is not a cleaner, you just spray it onto the oven surfaces (before use) and it forms a protective barrier which is left in place during use.
Just spray the oven protector inside the cooking area, wipe it evenly over the oven lining, and pre-heat for 30 mnutes to cure the coating.
Once the cooking session is oven just clean with the specially formulated Bradshaw oven cleaner spray.
