For anyone running a commercial kitchen, you know how valuable a combination oven—or combi oven—truly is. From baking to broiling to steaming, combi ovens are the jack-of-all-trades as they have the ability to cook and warm foods. Because of their ability to cook a variety of food products, and how frequently they’re used, it’s important to clean your combi oven on a regular basis. Below are general directions on how to perform cleaning tasks on a combi oven.
Please note: The following instructions are general directions on cleaning the interior and exterior of your combi oven. Since each combi oven is different, and various manufacturers produce combi ovens, your particular unit may require its own unique procedures for daily, weekly and monthly cleaning. In some cases, it might require a planned maintenance program with an authorized service company. Do not attempt to perform any cleaning procedures that aren’t recommended for an end-user as this can be dangerous.
General Daily Cleaning
Prior to cleaning your combi oven, refer to the manufacturer’s cleaning instructions and follow all directions and the recommended cleaning schedule. Additionally, your combi oven may be equipped to perform automatic cleaning, the directions of which should also be followed. Nonetheless, these are good general tips on cleaning your combi oven that are applicable for a wide range of models.
Be sure to use protective gear like rubber gloves and safety goggles before cleaning.
