Know the difference
Invest in a Quality Oil Sprayer - There are lots of cooking oil sprayers out there, but you want to make sure that you get the best one for your money. Look for a sprayer that has a non-drip spray nozzle, and a pump system. The Misto Oil Sprayer is a popular oil sprayer choice.
Clean Between Oils - If you plan on using your cooking oil sprayer for more than one variety of oil, it is a good idea to clean it between uses. For example, if you generally use your cooking oil sprayer to spray olive oil, you will want to clean the oil sprayer with soap and water before using it for sunflower seed oil. Cleaning your sprayer will help prevent cross-oil contamination, and preserve the flavor of the individual oils.
If you regularly cook with more than one cooking oil, you might want to invest in more than one cooking oil sprayer.
Use Pure Oils - Only use pure oils in your cooking oil sprayer. Avoid using cooking oils with chunks of herbs or sun-dried tomato floating in them. While these oils may be tasty, the chunks can clog your sprayer and prevent even spraying. If you like the flavor of an herb infused oil, try using a strainer to filter any herb chunks out of the oil before putting it in your cooking oil sprayer.
Clean Your Oil Sprayer Periodically - Even if you intend to use your oil sprayer exclusively for one type of oil, such as olive oil, you should still clean it periodically. This will prevent build-up and blockage, as well as clean out any dirt or dust that could collect in the oil sprayer nozzle.
Use Your Oil Sprayer Often - Use your oil sprayer often! Not only does your oil sprayer add great flavor to your food, and provide an even, non-stick coating while cooking, but using it frequently will prevent build-up and keep the pump in top working order.
Avoid Using Your Oil Sprayer Around Direct Flame - Since cooking oil is flammable, avoid using your oil sprayer around direct flame. Also, always supervise children who are using the cooking oil sprayer.
