11 Unexpected Things You Can Clean With Your Old Toothbrush

Things You Can Clean with a Toothbrush

Whether they are standard or electric, toothbrushes don’t last forever. But when it’s time to retire that old toothbrush, don’t just toss it out! There is plenty more you can do with it—or more specifically, clean with it! Think of your old toothbrush as a ready-made scrub brush that is perfectly suited for small cleaning jobs. The bristles are great at breaking up grime, and they can fit into tight spaces easily. (This is especially true of electric toothbrushes, which often have extra small brush heads. They can also provide extra scrubbing power when tackling tough messes! But a standard toothbrush often gets the job done just as well, so just use what you have!)

To help illustrate just how useful your old toothbrush can be, today I’ll be sharing a some of the more surprising things you can clean with it. My hope is that the next time you’re ready to retire a toothbrush, you’ll stick it next to the rest of your cleaning tools. I think you’ll be surprised at how often you end up reaching for it! :-)

11 Things You Should Clean With Your Old Toothbrush

1. Hairbrushes

An old toothbrush makes a great tool for scrubbing gunk and grime off of your hairbrush. You’ll be able to get into all those nooks and crannies easily! Check out the link below for some great tips on cleaning different kinds of hairbrushes.

2. Shower Head

If you have hard water like I do, then you might notice mineral deposits building up on your shower head over time. Those deposits can eventually block the flow of water, so its important to clean your shower head regularly. The easiest way I’ve found is to remove it, drop it in a container of vinegar, and let it sit for an hour or so. Then I use a toothbrush to scrub all the loosened gunk away, and it looks good as new! :-)

3. Jewelry

Your old toothbrush may be too soft to scrub your teeth clean, but it’s perfect for scrubbing jewelry! Add a drop of gentle soap to a cup of warm water, then dip your toothbrush in and scrub rings, necklaces, and bracelets clean.

4. Kitchen Sink

Use a toothbrush to scrub around the drain in your kitchen sink. It makes it much easier to get into all the divots of the rubber guard that covers your garbage disposal.

5. Car Vinyl

Use an old toothbrush to help clean the vinyl surfaces in your car! A toothbrush is the perfect tool for scrubbing ground-in dirt out of all those crevices.

6. Hair Dryer

Use a toothbrush to scrub the filter on the back of your hair dryer. That filter tends to be a magnet for hair, dust, and hair products, so it could use a good scrubbing every once in a while.

7. Dishwasher Filter

If your dishwasher has removable filters or screens, it’s important to keep them clean. Use a toothbrush to scrub away any grease or grime that may have built up on them.

8. Window Tracks

A cloth can help you wipe away most of the dirt and dust from your window tracks, but it might not be able to grab everything. Use a toothbrush to get at any grime that’s left in the corners.

9. Bathroom Faucet

Use a toothbrush to scrub out all the nooks and crannies around your bathroom sink’s faucet. You never know what kind of gunk is hiding in those small spaces!

10. Washing Machine Seal

For front-loading washing machines, one of the biggest challenges of maintaining them is keeping the rubber door seal clean. Use a toothbrush to scrub away any gunk that may be lurking in and around the seal.

A toothbrush makes a great helper when it comes to cleaning your small kitchen tools! Use it to clean your cheese grater, garlic press, microplane, sieve, or any other kitchen tools with small holes.

Bright Ideas

  • Boil a small pan of water. Hold the head of the toothbrush up to the ” neck”in the boiling water a few minutes. Grab a hot pad and bend the head back until it is 45 degrees. Let it cool to harden and you can get into even more tight, awkward places.

  • Sure, the toothbrush thing is very bright. it is a tool which has more uses after used it! Ideal to clean slime line in kitchen/bathroom tiles, edges, corners, etc. Also, to clean places if you cannot reach easily. If you fix a removable handle to it, much better. I have a small aluminium tube (taken from old TV antenna) for this purpose. You can push the toothbrush handle by heating (be careful!) it.

  • When retiring old toothbrushes, some have curled over side bristles. (Yes, I know it means I should have changed it earlier!) But that doesn’t mean the brush doesn’t have a lot more use in it. Hold it over the waste basket and give it a hair cut! Cut off the bristles until they are straight up and ready to really scrub. Nothing like getting a little more mileage out of a little tool!

  • I keep a “used” toothbrush in each bathroom as well as kitchen and garage for easy access. I use them almost daily (including this a.m. at about 6:30!). Along w/cleaning they make a great makeup tool for eyebrows and lashes.

  • If you run hot water over the plastic handle, you can bend it to suit your particular cleaning situation. I usually bend them up so the handle is at a 90 degree angle to the brush head.

  • I use old toothbrushes to clean the vents on electrical equipment such as microwaves etc. (remember to disconnect from the power supply before doing this). Also great for phones and computer keyboards.

  • A really soft old toothbrush is a great eyebrow tamer (mine broke at its narrowest point, making it a better size for this job). A stiff-bristled toothbrush is useful for scrubbing the white edges of athletic shoes. Another use for a dry one is brushing dust and crumbs out of the folds of my purse – inside and out. After using an old toothbrush, I run it through the dishwasher or throw it in with the laundry load I used it on so I know that all the toothbrushes in the storage box are clean enough for any use.

  • my 6 week old kitten found an old toothbrush under the bathroom radiator and now carries it around as a favorite possession, along with the dust bunnies from the same radiator.
    So add cat toy to used for re-purposed toothbrushes.

  • Great ideas. I occasionally have to use one to clean out my blow dryer filter- when it starts making that burning smell. Usually we keep the old toothbrushes under our bathroom sink. They are also excellent if I need to scrub on a tough stain before washing clothes.
