Most waffle makers in the market today claim to be non-stick but works differently. In whoever case, you can add oil or butter to the batter to avoid sticking. When selecting the best waffle maker, you can consider a solid cast iron one because you will have to season it. You can use vegetable oil, olive oil, or canola oil, which works perfectly before every use. After applying the oil is when you can add the waffle batter. For a non-stick waffle maker, you should not grease or season because it works best without any additions. That is because non-stick waffle makers have waffle iron plates that are coated in Teflon to prevent sticking. So, it would help if you avoided greasing or seasoning of non-stick waffles.
