Combining both a detergent and a rinse aid into one cartridge, the JLA Ultra Combi Oven WaveClean system makes it safe and easy to keep your combi oven looking like new. A wax seal on the cartridge means that you and your staff don’t have to directly handle chemicals – just pop the cartridge into a special holder in the combi oven, shut the door and press the start button. A closed wash cycle makes the WaveClean even more cost effective as you’ll use less water and energy during the process.
