Query: A big failure

I borrowed the scucni steam cleaner from my neighbor to clean the oven, and get te caked on greason from the unit's door. I had cleaned the oven with a cleanr before using the steamer, but the ot steam did nothing. The grease didnt comes off with ease, as it does in te infomercials. My sponge and elbow grease could've done a better job than the scunci steamer.
