Why You Should Wrap Foil Around Your Doorknob at Night If You’re Alone (and Other Clever Aluminum Foil Hacks)

Aluminum foil is a kitchen essential that, for many, serves primarily as a tool for cooking or wrapping food items. It's routinely picked up at the grocery store, but more often than not remains tucked away in the pantry or a drawer, with its full potential overlooked.

The truth is that aluminum foil is a versatile asset that offers a wealth of applications that extend well beyond its typical culinary uses, and it's high time we uncovered its potential.

Less Mess, Better Egg Shape

Adding a layer of aluminum foil to your frying pan before cooking fried eggs can reduce time spent cleaning. Just mold the foil to the pan and add some cooking spray to prevent sticking. Home cooks have also shared a secondary hack: making indents in the foil can help you create an egg with a perfect shape.

Bonus: this is also a good hack if you're aiming to make an egg scramble that you can wrap up for later!

Like any other cutting edge, scissors get dull with age. Even if you keep good care of them, eventually, they're going to be less effective than the first time you use them. Not only is a dull pair of scissors annoying, but they can also be dangerous to use if you're not extremely careful.

A simple trick to keep scissors sharp or eliminate any rust from the blade is to cut a piece of aluminum foil around seven to 10 times.

If you want to block your cellphone from receiving signals, simply use aluminum foil. Radio waves and fields that give your mobile device service can be blocked out by the product.

For this hack, wrap the foil around your phone. You shouldn't be able to make any calls or receive a signal once this is done, as a device surrounded on all sides by foil shouldn't receive any radio waves.

Stop Thieves From Breaking Into Your Car

The majority of drivers today use a key fob to unlock, start and lock their vehicles. These tiny devices emit a short-range, wireless radio signal from the key to the car, and drivers should be aware that criminals may be able to amplify and intercept this transmission if their fob is within close access to the car (around 300 feet or less).

ADVERTISEMENT

To help protect against this, keep your key fob more than 300 feet from your car. In an interview with the Detroit Free Press, Holly Hubert, a cybersecurity expert, said that wrapping the fob in aluminum foil can reduce the wireless radio signal, if this isn't possible.

If you've ever baked lasagna or a casserole, then you know the clean up is going to be rough. That glass or dish is going to need to soak for a while before you can begin to scrub off the stuck-on food.

Believe it or not, if your WI-FI signal is a little slow, aluminum foil can help!

Tear off a sheet and fold it into a rectangle, so it's about four inches by six inches, depending on the size of your router. Then, bend it into a curve with the shinier side facing the router. Incredibly, this helps to boost your Wi-Fi signal, so you don't have to wait 10 minutes for one video to load.

Nobody wants to own or use silverware that looks old and dirty, even when fresh out of the dishwasher. People will go to extreme lengths to get their silverware spotless, whether it's scrubbing them for hours on end or spending money on expensive cleaning products.

ADVERTISEMENT

However, none of that's necessary, as long you have some aluminum foil lying around. All you have to do is put some foil at the bottom of a container, add baking soda and salt, then pour boiling water. Place your silverware in the dish and let it sit for an hour. They'll come out looking good as new!

We've all somehow managed to give ourselves a minor burn on our fingertips, whether it's touching a pan that's too hot, an iron or anything hot enough to damage the skin.

ADVERTISEMENT

While most people's first instinct might be to put their finger in their mouth or run it under water, what you should actually do is reach for aluminum foil. Wrap your injured body part in the foil and leave it on for at least 15-20 minutes. The pain should be gone by then!

Bananas are an extremely popular fruit, but one of their biggest issues is that they go from unripe to ripe, to overly ripe in what feels like the blink of an eye. Why? As they ripen, these yellow delights release gas, which reacts with oxygen and causes the process to speed up.

ADVERTISEMENT

This process usually happens at the stem, so if you wrap tit with aluminum foil (either individually or as a bunch), they'll last for days longer.

To make the furniture slide across the ground with ease, place pieces of aluminum foil underneath each leg. With minimal effort, the piece will glide across the floor like skates on ice.

For some reason, household pets hate the feeling of aluminum foil on their paws, most likely because of the noise and lack of grip. As such, if you're trying to train your furry friend to stay off of the furniture, it might be the key to your success.

Lay sheets of foil on top of the surfaces you're trying to keep them from climbing. Of course, you can remove it if you need to use the surface, but after a few weeks, they'll stay far away.

Anyone with an ant problem will be happy to learn this aluminum foil hack.

Since ants are skilled climbers, they can easily scale the legs of a kitchen table to get to your food. Create a road block using foil! Since the product is slippery, the tiny pests won't be able to scale it. Place a section where you want to block them.

You can even apply Vicks VapoRub to make it even more difficult for these pesky insects.

Create balls using about three or four feet of foil, compressing them as tightly as you can, so they can't snag on any clothing items. Throw them in the dryer with your clothes and no more static!

If you think ironing is a laborious process that takes way too long, this is the perfect tip for you!

ADVERTISEMENT

When ironing, most of the heat gets lost on the board itself, meaning you need to go over a wrinkle multiple times to flatten it out. If you place a piece of aluminum foil beneath the fabric, it'll act as a conductor that reflects the heat through the clothing, getting the wrinkle out faster.

Simply scrunch small pieces of foil onto the positive end of the battery, making sure that it's touching both the battery and the wall of the holder. This will improve contact with the terminals, giving it a longer life. It won't last forever, but it can sure help in a pinch.

When painting, one of the main goals is to not get paint on anything except what's intended. If you don't want to go through the process of taking the knob off when painting a door, not getting paint on it can be tricky. However, using aluminum foil, you can wrap the knob tightly, running a utility knife around the base, so you can paint as close as possible.

You can do this with any other knobs you may end up touching with paint on your hands.

Fabric starch, softeners and even dryer sheets leave behind chemicals on your clothes that can end up leaving residue on your iron. In turn, the build-up on the bottom of your iron can end up getting on your clothes, which is counterintuitive.

To avoid this, place a length of aluminum foil on your ironing board and sprinkle half a teaspoon on salt on it. Turn your iron on and run it across the salty surface multiple times. As you go over the salt, the debris will be rubbed off.

We all know how great hot glue guns can be. They're effective, easy to use and you don't have to get glue all over your hands. Unfortunately, after most uses, there can be an adhesive layer on top, which can make it difficult to use the next time if it isn't properly cleaned.

When it comes to large bags of food, they don't always end up getting finished. This results in people rolling them or using a clip to try and prevent the contents from getting stale or infested with insects.

Unfortunately, this rarely works and the food can go to waste. A trick with aluminum foil is to cut out a strip and use it to pinch the bag closed. Then, go over it with a hot iron and the seal will be good as new.

To fix this issue, all you need is a sheet of aluminum foil and a clothing iron. Put the foil over the loose tiles and gently go over the area with the iron. The heat will help warm up the adhesive, settling the tiles back into place.

When painting, losing the lids to the cans or the caps of tubes can sometimes become an issue. Exposing paint to oxygen for an extended period of time makes it susceptible to oxidation, which will dry up the paint - and there's no coming back from that.
