You know the drill—you go grocery shopping and peruse all the aisles of beautifully colorful produce. You throw some kale in your cart, and then some blueberries. The broccoli and red peppers are on sale this week, so you get some of that.

Oh, and would you just look at those strawberries? Those red, juicy berries in that container are just staring back at you begging you to buy them. You’re not sure what you’ll do with them, but you toss them into your cart too.

You start thinking all the things you could make with the strawberries this week. You could totally make a strawberry pie or some homemade jam. Maybe some cheesecake-stuffed strawberries. Or you could just eat them with your eggs in the morning. There are tons of possibilities.

After getting home, you unload all your groceries and shove everything into cabinets and the refrigerator. Then as the week goes on, you get side tracked with life. Work is crazy. The kids have soccer. You’re trying to scramble together dinner each night, let alone have the time to make homemade jam.

In fact, you totally forgot about the homemade jam—and the strawberries. A few days later, you realize the strawberries you bought got shoved into the back of the fridge and have gone bad. There goes that! What a waste.

Unfortunately, it doesn’t take very long for strawberries to get moldy. But there’s good news: One (busy, we presume) mom recently shared her hack for keeping strawberries fresh in the fridge for weeks—weeks!—at a time.

The best part about it? It requires very little effort, very little time, and very little ingredients. And it works like a charm! It’s the perfect little hack for busy bees who constantly forget about the strawbs in the back of the fridge.

All you’ll need is a bowl, some water, and some white vinegar. Add your strawberries to the bowl, and then cover the fruit in one part vinegar to five parts water for a few minutes.

The vinegar essentially removes bacteria or mold spores (the culprits for causing strawberries to go bad as quickly as they do) from the strawberries much better than if you just rinsed them with tap water. In the vinegar mixture, you’ll actually probably notice some dirt and grime after you remove the strawberries—gross! But at least you know it’s working.

Once you remove the strawberries, make you to dry them as thoroughly as you can. Otherwise, the dampness might cause them to become susceptible to mold again. You can try putting them in a salad spinner to dry them off, or patting them with a paper towel.

Once dry, don’t put them back in their container—place the dry berries strawberries on top of a paper towel and keep them in the fridge. You’re going to be shocked at how long they stay that sweet, red color!

We know what you’re thinking, and no, the strawberries won’t taste like vinegar when you eat them. They won’t even have a hint of it! More good news: This trick also works for other berries, like blackberries, blueberries, and raspberries.
