The Grid Conditioner for waffle irons is a must to keep your waffle iron in top shape. Oil-based sprays will quickly cause carbon buildup and a sticky mess. You may only get weeks from your waffle iron plates using these types of sprays. The Grid Conditioner is a special formulation designed to keep your waffle grids clean and mess free while extending their life. It is NOT designed for being sprayed on every use. It is designed for interval cleaning so your customer doesn't need to spray every time. Make sure to follow directions on bottle completely.
