We’ve all been there. Scrolling through social media, you see a video promising a life-changing hack that seems too good to be true. And you know what they say about things that seem too good to be true, right? Well, I’ve tried my fair share of these “genius” tips, and let’s just say the results were… less than spectacular.
So, I’ve put together a list of the most popular life hacks that are, frankly, a total waste of time. Some are just ineffective, while others are downright dangerous. Let’s save ourselves some trouble and bust these myths together.
Using soda to clean toilets
The internet has been telling us for years to pour cola into the toilet for a sparkling clean bowl. The idea is that the phosphoric acid in the soda lifts stains. While it can handle very light stains, the acid concentration is so low that it’s almost useless against real grime. You’ll end up scrubbing just as hard, if not harder, for a disappointing result.
Even worse, the sugar in soda leaves a sticky film behind. What loves a sticky, sugary film? Bacteria. You’re essentially turning your toilet into a five-star restaurant for germs. A proper toilet cleaner has strong acids and disinfectants. Cola has neither. This hack is a complete fizzle.
Toothpaste for clearing pimples
I remember trying this one as a teenager, desperate to get rid of a pimple before a big day. The logic seems to be that toothpaste dries things out, so it must dry out a pimple. But modern toothpaste is not designed for your skin. Most brands have removed triclosan, the one ingredient that might have had some antibacterial effect.
What’s left are things like hydrogen peroxide, alcohol, and baking soda, which are known skin irritants. The American Academy of Dermatology warns that this can clog pores, cause chemical burns, or make your acne worse. Instead of a quick fix, you could end up with redness and even lasting pigmentation changes. Just stick to products with benzoyl peroxide or salicylic acid.
Microwaving grapes to make plasma
Viral videos showing grapes creating a glowing plasma ball in a microwave look like a cool science experiment. But this is one trick you should definitely not try at home. Scientists confirmed that when you microwave two grape halves close together, they can create electromagnetic hotspots that generate plasma. Sounds cool, right?
The problem is that this process creates intense heat that can destroy your microwave. There are many stories of this “kitchen firework” show leading to ruined appliances and actual fires. It’s a fun thing to watch in a controlled lab video, but in your kitchen, it’s just a recipe for disaster.
WD-40 for shining everything
WD-40 is a workshop staple, and some people swear by it for shining all sorts of surfaces. While it can make some metals gleam, it’s terrible for many other materials. Its petroleum-based formula can strip the finish off wood, leaving it dull, discolored, or sticky.
On certain plastics, like polycarbonate or acrylic, it can cause cracking or clouding. The oily film it leaves behind is also a magnet for dust, which means you’ll be cleaning more, not less. Using WD-40 on the wrong surface can cause permanent damage that far outweighs a temporary shine.
Putting phones in rice to dry them
This is probably one of the most famous emergency tips out there. You drop your phone in water, and the first thing everyone says is, “Put it in rice.” But tech experts, including Apple, have debunked this myth. Studies show that a bowl of rice absorbs very little water from a phone’s interior. In fact, just leaving it out to air-dry is often more effective.
The bigger issue is that rice dust, starch, and tiny grains can get into the charging ports and headphone jacks. This can cause more corrosion or even lead to electrical shorts down the line. If your phone takes a swim, your best bet is to turn it off immediately and take it to a professional. Skip the pantry.
Melting crayons into emergency candles
The idea of turning a box of crayons into emergency candles seems clever, especially for a survival kit. It’s a classic DIY hack that pops up from time to time. However, crayons are made from paraffin wax and chemical pigments that were never meant to be burned. When you light them, they can release toxic fumes.
These makeshift candles also burn very unevenly and often go out unexpectedly. Plus, they drip colored wax everywhere, creating a mess instead of providing a reliable source of light. This is a perfect example of a hack that is more hazardous than helpful. Just use actual candles.
Freezing jeans to “clean” them
This hack claims that sticking your jeans in the freezer will kill odor-causing bacteria, saving you a trip to the washing machine. It sounds like a great way to conserve water and keep your denim looking fresh. Unfortunately, the science just doesn’t support it.
Microbiology experts say that freezing only makes bacteria go dormant. As soon as your jeans warm up to room temperature, the bacteria wake up and the smell comes right back. To truly clean your jeans and get rid of the bacteria, you need soap and water. Your freezer is for ice cream, not for laundry.
Using nail polish to fix cracked screens
A cracked phone screen is a major annoyance, so a quick fix like dabbing some clear nail polish on it seems appealing. The idea is that it will fill in the crack and make it less noticeable. While it might briefly hide the cosmetic flaw, it’s a terrible idea in the long run.
Nail polish can seep deeper into the crack and damage the layers of the display underneath, causing discoloration or interfering with the screen’s touch sensitivity. No professional repair technician would ever recommend this. It’s a temporary fix that can cause permanent damage. Your best bet is always a proper screen repair.
Charging a phone with a lemon
You’ve probably seen the science fair project where a lemon powers a tiny light bulb. Some viral videos take it a step further, claiming you can charge a phone with a few lemons. While you can create a small electrical current, it’s nowhere near enough to charge a modern smartphone.
One experiment calculated it would take about 1,000 lemons to get a standard phone to charge by just one percent. Phones require a stable voltage and enough current, which a piece of fruit simply can’t provide. This hack is memorable, but it’s pure fiction.
Using vinegar for all cleaning
Vinegar is a fantastic natural cleaner for some things, like glass and soap scum. Its popularity has led people to believe it’s a cure-all for every mess in the house. But vinegar is an acid, and it can damage certain surfaces. You should never use it on natural stone like marble or granite, as it can etch the surface.
It can also damage the protective finish on hardwood floors. And while it has some disinfectant properties, the EPA does not list it as an approved disinfectant for killing dangerous pathogens. For serious germ-killing, you need something more substantial.
DIY aluminum foil Wi-Fi boosters
If you have a spotty Wi-Fi signal, you might have seen this hack: wrap some aluminum foil behind your router’s antenna to direct the signal where you need it. The theory sounds plausible, as foil can reflect signals. However, in practice, it rarely works as intended.
More often than not, this homebrew solution creates more interference and unpredictable dead zones. It can even cause your router to overheat. Tech experts agree that if you want to improve your Wi-Fi, you’re better off repositioning your router or investing in a mesh system.
Taping remote controls to walls
Losing the remote is a universal frustration. So, why not just tape it to the wall? Problem solved, right? Well, you’ve traded one minor inconvenience for a much bigger, more permanent one. Now, every time you want to change the channel or adjust the volume, you have to get up and walk across the room.
This completely defeats the purpose of having a remote control in the first place, which is convenience and comfort. A much more practical solution is a remote caddy or a simple tile tracker. Let’s keep the remotes where they belong: on the coffee table.
Mixing bleach and vinegar for “deep cleaning”
This is by far the most dangerous hack on the list. Some people think that if two cleaners are good, mixing them must be even better. When it comes to bleach and vinegar, that assumption is incredibly wrong. Mixing these two chemicals creates toxic chlorine gas.
Inhaling chlorine gas can cause severe respiratory distress, and in a poorly ventilated area, it can even be fatal. The CDC warns that hundreds of household poisoning incidents are reported every year due to this specific mistake. There is absolutely no cleaning task that requires you to mix these two chemicals.
Microwaving sponges to disinfect them
The idea of quickly zapping your kitchen sponge in the microwave to kill germs sounds easy and efficient. But studies have shown that microwaving is not an effective way to sanitize a sponge. It fails to kill many of the bacteria that live deep within the sponge’s pores.
Even more concerning is the fire hazard. If a sponge is too dry, it can easily catch fire in the microwave. The U.S. Fire Administration has even logged cases of house fires started this way. A much safer and more effective way to clean your sponge is to run it through the dishwasher or boil it in water.
DIY tooth whitening with baking soda and lemon juice
Everyone wants a brighter smile, and this DIY whitening paste made from baking soda and lemon juice is a popular internet tip. Dentists, however, see the damage this concoction can cause. The acid in lemon juice is strong enough to erode your tooth enamel, which is the protective outer layer of your teeth. Once enamel is gone, it doesn’t come back.
The baking soda acts as an abrasive, which can make things worse and leave your teeth feeling sensitive. A study from the Journal of the American Dental Association confirmed that combining acids and abrasives leads to enamel loss. This is one hack that could end with a costly trip to the dentist.
Ket takeaway
It’s easy to get drawn in by a clever hack that promises to save you time or money. But as we’ve seen, many of these tips are ineffective at best and dangerous at worst. The next time you visit a viral “genius” trick, take a moment to think it through. Sometimes, the old-fashioned way is the best way for a reason.
