All of your cast iron products — including the rEGGulator from time to time — require a light brushing of oil. This will help prevent rusting and also stop your food from sticking. Don’t wash your Cast Iron Searing Grid in the usual way, as you'll remove the seasoning that's baked in; the same seasoning that helps to prevent food from sticking, and give your sears an amazing flavour.
Instead, brush down after use with a non-abrasive cloth, and then season with oil.
Our top tip: for the best results, dab the grid with rapeseed oil. It has a higher burning temperature and won’t leave a bitter taste once burnt.
