To clean all the splatter and gunk from inside your microwave, squeeze a whole lemon into a bowl with 2 cups water. Microwave on high for 4 minutes. This loosens all the dried up gunk so all you have to do is wipe it off. Not only will your microwave be clean, it'll smell lemon fresh! If you don't have a lemon, don't worry the lemon is just for nice scent, this trick will still work with just water.
If you get sharpie or ink pen on your microfiber couch, use rubbing alcohol! It brings it right out without smearing or leaving a water mark! Also works on walls and carpet!
