I'm still stunned how easy it was. If I had a spray bottle and a bit more time I'd spray soapy laundry water inside the oven and let it sit and wipe it out. But I just did the bottom of the oven & the door with a scourer & dishwashing liquid and then enjo'd it all off.. came up really good. the sides & top of the oven can wait.. they're not visible LOL.
