Why You Shouldn’t Store Onions Near Your Toothbrush (and What to Do Instead)

One morning, I walked into the bathroom and nearly tripped over my own brain. There it was, a glass filled with sliced onions, sitting casually beside my brother’s toothbrush. He was brushing his teeth like this was the most natural thing in the world. When I asked why on earth he’d do that, he shrugged and said, “It’s efficient.”
I didn’t know whether to laugh or leave the house.

That odd moment led me down a little rabbit hole of questions: Is storing onions in strange places a thing? Can kitchen habits bleed into the bathroom? And most importantly, should they? Let’s explore the weird, the practical, and the mildly alarming together.

Why Would Anyone Store Onions in the Bathroom?

Let’s be honest, it’s not the first place that comes to mind. But maybe, just maybe, there’s logic behind the madness.
Some people believe onions absorb odors or even purify the air (though science is still on the fence). Your brother might think placing onions by the sink keeps things “fresh” or handy for the next meal. It’s also possible he just ran out of fridge space or doesn’t want the smell spreading in the kitchen.

It sounds strange, but sometimes habits are born out of convenience rather than common sense. In small apartments or busy homes, people come up with creative ways to save time, or at least they think they do.

The Real Problem: Cross-Contamination

Now, let’s look at it from a cleanliness point of view.
Onions have a strong smell. You already know that if you’ve ever chopped one and had your fingers smell like them for the rest of the day. Bathrooms, on the other hand, are… well, not exactly known for their freshness. Placing food anywhere near toothbrushes isn’t just odd, it’s questionable.

Your toothbrush can easily pick up scents and particles from the surrounding air. And while an onion won’t harm you, the idea of brushing your teeth with a side of onion aroma? Not ideal.
Plus, bathrooms have moisture. And moisture near fresh-cut vegetables? That’s a quick way to speed up spoilage or encourage bacteria. That “efficient” system might be doing more harm than good.

Let’s Talk About Storage That Makes Sense

So, where should onions go?
The best place for sliced onions is either:

  • In the fridge (sealed in a container or bag to reduce odor).
  • In a clean jar with a lid.
  • Or used immediately and not stored at all if possible.

If your kitchen doesn’t have a lot of space, consider getting a small airtight container stack or a fridge organizer. They’re easy to find and make a huge difference. Keeping onions away from anything related to hygiene or grooming is a good idea, for your health and your peace of mind.

When “Efficient” Becomes a Red Flag

It’s totally fair to love shortcuts. We all do. But sometimes what feels efficient is really just… strange.
Your brother may genuinely think he’s saving time by keeping his onions there, maybe to chop them quickly in the morning or to reuse them somehow. But this setup blurs two spaces that serve very different purposes.
Kitchen = food prep.
Bathroom = personal care.
Mixing them? Not the best combo.

It’s not about judging someone’s habits harshly. It’s about drawing gentle lines between what works and what just feels… off. If it makes you feel uncomfortable or even question the safety of what you’re eating, that’s reason enough to speak up.

How to Gently Suggest a Better Option

If this is your sibling, roommate, or even spouse, you might wonder how to bring it up without starting a small war.
Try this: “Hey, I get you want to save time, but storing onions near a toothbrush seems a little risky. I read that bathrooms can actually make food spoil faster. Maybe we can clear a spot in the fridge instead?”
It helps to come from a place of curiosity instead of judgment. People are more open to change when they feel heard rather than attacked.

The Bigger Lesson Here

Odd habits often start with good intentions. We try to make life a little easier, save a step, or simplify something. But not every shortcut is worth taking – especially when it crosses the line between food and hygiene.
Sometimes, we need a second pair of eyes to realize what we’ve normalized isn’t all that normal. And that’s okay. These quirks make us human. They also give us funny stories to tell, like the one about the onions living in the bathroom.

Final Thoughts

So, should your brother keep onions next to his toothbrush? Probably not. But the story does highlight how creative people can be when it comes to managing space and time.
Let’s embrace the creativity, laugh at the weird stuff, and gently guide each other toward better, safer habits – especially when onions are involved.
Would I eat anything that came out of that glass? Let’s just say… I’ll pass.
