To steam clean oven racks and glass, you need a steam cleaner that comes with suitable tools to clean the whole oven. Karcher includes all those tools that make your oven like a new one.
When the machine gets ready, attach the brush head with a microfiber pad to the steam cleaner.
Open the oven, press the button or trigger to start the steam cleaning from inside. It simultaneously performs cleaning and scrubbing with the help of the attached tool. As a result, the hard residue loosens its grip, grease melts, and finally, the microfiber pad wipes it all away at the same time.
To clean the glass, handle and knobs, microfiber cloth is safe and good to apply. For outside the glass, you can use a window nozzle attachment. This will give you a streak-free cleaning.
