Here are a few that I tried...
For an easy-to-clean oven and stove top, sprinkle with baking soda, then mist with water. Let soak, wipe clean.
Soaking burned casserole dishes? Add an old dryer sheet and let soak overnight. Wash and rinse clean.
For brilliant shine on faucets, buff with olive or vegetable oil using a dry rag. Rinse oil with club soda and wipe dry.
Now if I could only find a cleaning agent for my toughest job...cleaning Max after meal-time.
