While this much-debated topic might seem like a personal preference, we can tell you "over" is more sanitary, because the paper is further from the wall. Also, the patent for toilet paper from 1891 shows the inventor intended for it to be hung "over." So there's that.

Place liquid ingredients in the jar first, followed by the rest of the ingredients. The swirl created by blending the liquids will pull the solids down, making sure you get even blending.

No more broken nails: To add to a key to your ring, wedge a staple remover's teeth between the coils, then clamp down to separate them — a new key will slide on easily.

Even though it's tempting to see how your soup is coming along, slow cookers work by trapping heat and using it to cook food over a long period of time. Every time you lift the lid, your appliance loses heat and the cooking process slows down.

Did you know there are two kinds of plungers? There's the design shown in the photo, made for your toilet, and the other, that only features the cone on top, made for your sink.

Put the most heavily soiled items in the center of the bottom rack facing the spray arm. And make sure nothing big is blocking the detergent dispenser; it could impact how it opens and keep dishwasher detergent from being dispensed properly.

Confused? Well, if you want to avoid making a crumbly mess while eating this treat, you should push pieces towards the box to break them off instead.

To prevent scratching, use wooden spoons to stir food, avoid steel wool, and don't stack these pans. This will also help extend the life span of your cookware.

You actually need to store it upside down so that when you take it out, you can flip it, open it, and (voila!) the oil is on the bottom.

If you want your stand mixer to work even better, chill the bowl and beater. When they're cold, they'll help you whip up the loftiest, fluffiest dessert possible.

This method will result in blotchy, streaky results. Plus, touching your skin with your fingers all the time can do more harm than good. Instead, use a damp makeup sponge like the EcoTools Total Perfecting Blender or foundation brush.

Did you ever consider why there's a hole in the middle of spaghetti spoons? You're supposed to use that hole to determine how much spaghetti to cook per person. Genius!

Always empty the iron's water tank before putting the iron away, especially if you store it on its soleplate. This keeps excess water from damaging the internal parts and leaking through and discoloring the soleplate.

Zero degrees (or even lower) is the best temp for long-term frozen food storage, so set your freezer as low as it will go. And if you find that your ice cream gets too hard to scoop, store it on the door where the temperature will be the highest.

Before chopping, cut food into chunks for even processing. This also helps to drop chopped pieces through the feed tube while the food processor's in operation, instead of loading them all in the bowl before you start.

No, it won't make your whites whiter. Use too much and it might not rinse out of clothes — and too many suds can cushion fabrics and dirt so stains get trapped and not washed away as they should. Instead, just follow the instructions on your bottle.

This cleaning superhero won't, in fact, be that helpful if you don't sanitize it every few days (and replace it every month). To do this, soak your sponge in water, place it in a microwavable dish, then heat it on high for a minute.

When packing clothes that wrinkle easily, lay the item inside a sheet of tissue paper (dry-cleaning bags work too) and fold as normal. The tissue will prevent creases from setting in.

While this grease-fighting product is powerful, it leaves streaks behind on surfaces that aren't plates and cups. So you should steer clear of using this liquid soap on your car windows and mirrors.

These tools are your best friends! They make cleaning much easier, and pick up dust and allergens from areas you might otherwise overlook.

Since your coffee maker is a hot bed for bacteria and mold, we beg of you: Wash every removable part after each use — not just the pot. Think how much better your coffee will taste each morning!

If you put in your bobby pin with the grooved side up (like most people), we have bad news: you're doing it wrong. The grooves are intended to help the bobby pin stay in place, so having them face outwards isn't as effective.

When you use a vegetable peeler to shave thin slices of an onion, you can speed through the chopping process ... hopefully before your eyes start to well up.

If you've been scooping your honey or fruit into your yogurt, you're doing it wrong. It turns out, you can fold the container in half so your toppings pour directly on top.
