the nastiest oven in the world

We have completed the move into our new house, everything is unpacked and set up. So now comes the serious defilthing. When we looked at the house I completely missed the nastiness. Why because the woman who owned the house before us was an excellent surface cleaner. Everything was straightened and decorated so that you wouldn't notice the grime. To be honest maybe she didn't either. Its okay to keep things surface cleaned most of the time, because lets be honest none of us have time to clean EVERYTHING all the time. BUT, you've gotta keep things to a decent level in the deep cleaning department. Nothing in the house was deep cleaned. Midew in the showers, grime on the kitchen cabinets, and the oven, the oven well that was my whole weekend.
This oven and stove top looked as if they hadn't even been wiped down in the 2 years that they lived here. The remains of every meal that had ever boiled over on the stove were still there just burnt now, and I think she must have spilled things very often. Yuck! There was grime holding the stove pans on to the stove so that I couldn't tell how to remove them till halfway through the process. And the oven racks were apparently used as grills. Everyone out there Please don't EVER use your oven as a grill BBQing is an outdoor thing, and should never be attempted in your oven. I guarentee the sauce will be hard to get out of the oven.
So after all weekend, my skin is peeling off my hands and my whole family is high on oven cleaner, but I can now say for sure that my stove is steel. So for future reference demand a clean oven before you sign papers.
