Question about Kärcher SC 3 EasyFix

Unfortunately I have no idea, we have an oven with pyrolysis (self-cleaning)

Yes, fit a head at the end of the wand, like a soft brush. This will gently scrub the oven without damaging it, making it easier to remove stubborn residues. Set the steam cleaner to a high level. Then activate the machine and send out the steam, bringing the nozzle into direct contact with the walls of the oven and the glass.

No idea... sorry...
