Let's be honest: there's nobody wiser or smarter than a grandma. With a wealth of experience and life knowledge under their belts, grandmas know just about everything - and they have some pretty impressive old-school life hacks to show for it. From home and clothing repair to completing house chores in record time, you can bet your bottom dollar that grandmas have mastered it all. Don't believe us? Check out these grandma hacks that will make your life much easier - and cheaper.

Add Celery to Prevent Dry Bread

While dry bread can be repurposed to make croutons or bread pudding, nobody wants a sandwich made from dry bread. But most people assume that you have no control over the dryness of your bread - and that's just not true. Back in the day, our grandmas would use another kitchen ingredient to prevent dryness, and they used to stick a stalk of celery into the bag or bread container.

The moisture within the celery will stop the bread from drying out and keep it fresh and soft for much longer than without it, but just make sure that you change the celery stick every few days.

Preserve Fresh Flowers With Vinegar

There's nothing quite like having freshly cut flowers in your house, but it can be pretty sad when they start to wilt a die just a few days later. But as you can probably guess, this grandma hack can solve that issue. To preserve your flowers for longer, simply add a half-and-half mixture of vinegar and water to a vase of water. The antibacterial properties of vinegar will help them maintain their freshness.

It'll also keep harmful microorganisms at bay, but only if you change the water and refresh this mixture every few days. If not, the antibacterial properties won't be as effective.

Fill Wall Holes With Toothpaste

You could spend your whole life ticking house chores off your home maintenance list. It seems as though taking care of your home is a never-ending job, and this is especially true when you have holes in your walls. But while you could head out to Home Depot and buy some filler, this old-school hack involves toothpaste instead. In fact, you can use this toothpaste as a putty to fill the holes with ease.

When the toothpaste has dried out, you can then sand the area and paint over it. And within just a few hours it'll be like the holes were never there.

Absorb Trash Can Odors With Newspaper

Don't you just hate it when a trash can stinks out your whole house? Although we know that adding leftover food and rotten vegetable peelings into a trash can won't leave it smelling like roses, it's still a shock to the system when it burns your nostrils. This grandma hack can solve that problem, though. Back in the day, our grandmas would line the bottom of their trash cans with newspaper - but for some reason, we've stopped doing that.

However, this old-school hack is extremely effective as it acts as an absorbent layer to soak up spills and odours. It's also a cheap hack, as you probably have some newspaper lying around the house anyway.

Use Lemon and Salt to Clean Brass and Copper

Whether you have some brass hardware around your house or you've inherited some copper pans from your grandma, knowing how to take care of them is key. A big part of that is cleaning, but there's no doubt about the fact that you could spend a fortune on cleaning supplies that all claim to be the best product for the job. But one grandma hack we can't ignore is totally free!

Yes, if you cut a lemon in half and sprinkle some salt on the flesh, you can rub it against your brass or copper and clean it up a treat.

Chill Onions for Tear-Free Cutting

Hands up if you cry when you cut onions? Of course, it's not because we're so emotional over the onions and their layers, but it is instead because of the chemical makeup of the onion itself. But if you want to cut onions without having a meltdown in the process, the old-school hack of chilling your onions before you cut them should work wonders. After all, our grandma's taught us it.

All you need to do is chill your onions in the refrigerator for around 30 minutes before you cut them, and this will stunt the release of the irritating compounds.

Open Stubborn Jars With Dishwashing Gloves

If you struggle to open stubborn jars of cooking sauces, you've probably tried every trick in the book. But have you ever tried this grandma hack? Back in the day, our grandmas would use an old-school hack that would allow them to seamlessly open stubborn jars with dishwashing gloves - and it works every time. That's because the material of the dishwashing gloves offers impressive grip, allowing you to really get a hold of the lid.

There's no more slipping and sliding when you use these gloves, but you don't have to worry if you don't already own a pair. You can pick some up for just a few dollars at the grocery store.
