And unlike many internet “life hacks” that overpromise and underdeliver, these have earned millions of views and comments for one reason: they work.
Whether you are battling spoiled herbs, fighting with stubborn bottle caps, or just want to level up your morning routine, here are 10 TikTok-approved tricks that have proven both simple and surprisingly effective.
1. Bottle cap bag sealer
Grab an empty plastic bottle (like a water or soda bottle) and cut off the top part, the neck and cap included. Then, take your open snack bag and slide the cut bottle top over the open end from the bottom.
Pull the plastic bag through the neck, twist it tight, and screw the cap back on. Just like that, you have got a DIY seal that keeps air out and your crisps or biscuits fresh for longer.
2. Microwave lemon steam cleaner
If you hate scrubbing your microwave, just slice a lemon, place it in a bowl of water, and microwave it for three minutes.
Ensure you keep checking the water so that it does not finish in your bowl. The citrus steam loosens grime and food splatter, making cleanup as easy as a single wipe. The lemon also ensures your microwave smells great.
3. Leftover coffee ice cubes
Instead of pouring out that half cup of morning coffee, pour it into an ice tray and freeze it. So that next time you make iced coffee, you use the cubes instead of regular ice, to keep your drink cold without watering down the flavour.
4. Avocado + red onion trick
Avocados spoil fast once cut, even if you put them in the fridge. But TikTok users discovered that storing your avocado with a slice of red onion in an airtight container keeps it green longer. The natural sulfur in onions slows down oxidation, making it last longer.
5. Egg yolk separator (water bottle method)
One of the platform’s most satisfying food prep hacks involves using an empty plastic bottle to separate egg yolks.
Crack the eggs into a bowl, then squeeze the bottle and gently release to suck up the yolk, leaving the white behind in the bowl.
6. Micellar water face mist
Micellar water is already a cult-favorite cleanser, but creators are now pouring it into spray bottles to create on-the-go facial mists.
This is ideal for freshening up after a workout, if you are commuting, or after a long day. Also, a spray means your product will last longer. And there will be no sink required.
7. Alarm clock upgrade: wake up with a podcast
Instead of waking up to a loud and noisy alarm tone, TikTokers recommend setting your alarm to a calming podcast or a motivational voice note.
It is a gentler, more mindful start to the day, and less likely to trigger the snooze reflex. You are likely to wake up happier than angry.
8. Hair conditioner as shaving cream
If you ran out of shaving cream, TikTokers swear by using hair conditioner as an effective alternative. It softens hair, hydrates skin and allows razors to glide smoothly as you shave. This is also great for travellers who want to pack light.
9. Dhania (Cilantro) and spinach storage solution
If you cook with fresh herbs like dhania (coriander) and have delicate greens like spinach, you have likely watched them wilt in the fridge within days.
The TikTok solution is to wrap the herbs and greens in a dry paper towel and store them in a sealed container. This hack can keep them fresh for over a week.
These hacks may have started as casual TikTok content, but many have found loyal followings in real life.
They offer a reminder that social media, often criticised for being superficial, can sometimes deliver simple, clever ideas that make our lives easier, cleaner, and a little less stressful.
