10 Amazing Uses for Your Old Toothbrush

Has your toothbrush reached the end of its days? While it may not be able to keep your teeth clean anymore, it may be useful in other ways. Before you toss it in the trash, check out these ten amazing uses for your old toothbrush.

  • Grout Cleaner

Cleaning those hard-to-reach grout spaces between your kitchen or bathroom tiles can prove to be a bit tricky. No worries - a toothbrush is the perfect size to thoroughly scrub the narrow space with no difficulty at all. 

To clean the grout, you can use your cleaning solution of choice, or you can use some baking soda or bleach. Apply the solution to the head of your toothbrush and get to work scrubbing! You’d be surprised what easy work your old toothbrush makes of cleaning up the grout.

  • Keyboard Cleaner

Dirt and grime tends to build up in our computer keyboards over time. The small spaces between the keys can be tough to reach, but an old toothbrush can do the job just fine. Use a dry or slightly damp brush to clean your keyboard, and make sure that you tilt the keyboard as you clean it to ensure that all the dust falls out.

  • Car Detailer

The inside of your car is filled with various small, hard-to-reach spaces that can quickly build up with dirt, grime, and dust. Before you head out to buy an expensive car-detailing toolset, consider using your old toothbrush. An old toothbrush can be a small yet effective tool that helps you to reach every nook and cranny while detailing the inside of your car. Never leave any hard-to-reach dirt and grime behind in your car again!

  • Shoe Cleaner

The crevices on the soles of your shoes may prove to be a bit tricky to thoroughly clean. Thankfully, an old toothbrush is the perfect tool for removing dirt, mud, and other debris from the crevices of your shoes. Keep an old toothbrush on hand for cleaning your shoes; you’ll save yourself the time and effort that would have otherwise been spent mopping or sweeping the floors!

  • Clean Small Appliances

Small kitchen appliances such as toasters, coffee makers, and microwaves all have little spots that build up dirt and grime over time. Use your old toothbrush to clean these hard-to-reach areas, leaving your small appliances squeaky clean and gleaming!

  • Crayon Marks on Wall

Children love to scribble on walls with crayon, but don’t stress! You can use your old toothbrush and a dab of shaving cream  to quickly and efficiently scrub the marks off the wall. This technique works like magic! You’ll never be able to tell where the crayon scribbles were on your walls.

  • Clean Hair Dryer Vent

A dirty or clogged hair dryer vent has the potential to become dangerous. Use your toothbrush to regularly clear out the vent, which helps your hair dryer run smoothly and prevents a potential fire risk.

  • Clean Out Your Hairbrush

Removing hair from your hairbrush can sometimes be a bit tricky. An old toothbrush is able to easily lift the hair from the bristles and makes easy work of cleaning out your hairbrush.

  • Clean Jewelry 

Necklaces and rings have tiny crevices that trap dirt and grime over time. No one likes to wear jewelry that has lost its beautiful shine, but thankfully, you can use your old toothbrush to remove the grime and reveal gleaming jewelry that looks brand new!

  • Clean Blinds & Window Screens

Dirt and dust clings to window screens/blinds and builds up over time. Using an old toothbrush ensures that you can thoroughly clean them without causing any damage. 


Moving forward with the information that you have learned here, you’ll have a clear idea of just how useful an old toothbrush can be. Before you throw that old toothbrush in the bin, think of all the helpful ways it can be used around the house and in your car.
