Grip 304 Professional Oven Gel 5L is a ready to use product for maintaining clean and hygienic ovens, a powerful formula designed to cut through and break down baked-on grease and oil and remove carbon deposits from surfaces inside the oven. This product is thickened to allow it to 'cling' more effectively to vertical surfaces and strong enough to clean the heavy carbon build up often found on the floor of the oven. Works best when applied with paint brush or cloth to the inside of a (switched off) warm oven and left to react for 15 minutes before wiping and rinsing away.
