Every Wood Pizza Oven should be cleaned every 3 months. Maintaining your unit is integral to its longevity. Over the years we have found old food, cleaning rags and paper towels beyond regular wood creosote. These items are harmful to your unit as they may catch fire and cause damage to integral parts of the unit including the liner and duct system. If your restaurant burns real wood daily, it should be serviced quarterly, every 3 months. Every pizza unit is designed and installed uniquely to the restaurant; therefore an assessment of the unit may be required prior to cleaning. Our Pizza Oven Hood Cleaning process ensures 99% creosote dust control that helps to keep the restaurant clean at all times.
