Ketchup naturally cleans your oven
If a stubborn stain keeps burning in your oven, turn the oven on very low to warm it up. Then, squirt ketchup on the culprit, scrub and let sit for five minutes; it’ll wipe right up! You can also restore discolored copper pots by spreading a thin layer of ketchup on, then rinsing and drying.
Aluminum foil naturally cleans silver
Tarnished silver is no match for this aluminum foil “recipe.” Bring 1 liter of water, 1 tbsp of baking soda and one piece of aluminum foil to a boil. Drop your silverware in the pot for 10 seconds (longer if it’s extra tarnished), then fish it out with tongs. Magic! You can also ball up foil and use it to scrub off caked-on food from pans (not non-stick ones).
