Prevent bubbling over with a wooden spoon.
If any of your pots are boiling over, quickly place a wooden spoon across the rim—that'll settle the frothy bubbles and prevent more over-boiling.
Use rubbing alcohol to clean stainless steel.
Put some on a few cotton balls and go at it!
Run your potatoes through the dishwasher.
Seriously, it's a foolproof way of cleaning your dirty vegetables when hand-washing won't suffice. Make sure there's no soap in the machine, of course, and a simple rinsing cycle will do the trick.
Heat a dish towel in the microwave to get rid of fish smell.
Trust us: If you put some dish soap on your dish rag, heat the rag itself for a few minutes, leave the rag in the microwave for about half an hour, return to the rag, and wipe the walls of the microwave down, you will be free of that fishy microwave smell that's been plaguing you since, well, the last time you microwaved fish.
File your cookie sheets.
You can use an actual filing system to hold your baking sheets upright and in an orderly fashion. It might not look very cute, but it'll make your life infinitely easier than having to climb to the top of your highest cabinet to get to them.
Use salt to soak up eggs.
In the off chance you drop a raw egg (I mean, it never really happens) (I'm kidding, this is the worst and most common kitchen problem ever), throw some salt on the remnants. It'll soak up the egg whites. Science! Magic!
Polish your copper with ketchup.
Dab some ketchup (yes, ketchup) on a cloth and rub it all over your copper. Rinse it in warm water and voilà: good as new
Microwave your sponge.
For just a few seconds when it's (seemingly) irreparably gross.
Use cooking spray to make less of a mess.
When measuring out super sticky ingredients (hey, @honey, I see you), coat your measuring cup with a butter- or oil-based cooking spray first. It ensures the sticky substance will slide right out and prevent you from having to scrub at your cups forever afterward.
