10 Ways to Repurpose Old Toothbrushes to Save Time and Money

Last Updated on

Have a spare old toothbrush lying around? Dont throw it away! Instead, try one of these ways to repurpose old toothbrushes. I have SO many of them! I am slightly anal retentive about getting all of us to the dentist twice a year. Of course, at each of these dentist appointments we get a new toothbrush. That means 8 old toothbrushes need to find new uses every single year. On top of that, I tend to replace toothbrushes randomly when they are looking particularly worn or someone is sick. I am always looking at those old toothbrushes and wondering what in the world I can do with them besides throw them away. I decided I needed to put together a list of things that I could do with our old toothbrushes so I can stop feeling so guilty every time one ends up in the trashcan. Once you find a new use for your old toothbrush, check out my other eco friendly bathroom ideas as well.

10 Ways to Repurpose Old Toothbrushes

  • Clean the dog’s teeth:  They make fancy doggie toothbrushes but couldn’t I just use one of our old toothbrushes instead? Along with some canine toothpaste I bet it would go a long way towards freshening up her breath!
  • Bathroom faucet cleaning:  I know I’m not the only one who gets that nasty buildup at the bottom of the sink faucets. Old toothbrushes are great for scrubbing that away.
  • Clean computer keyboards:  All that crud that falls in between your keys because you are snacking while you type? Old toothbrushes are great for getting into those crevices!
  • Clean jewelry:  If you wedding ring is looking a little bit dull just use an old toothbrush along with some jewelry cleaner and get it looking brand new.
  • Scrub your nails:  After gardening I always have tons of dirt under my nails. Old toothbrushes are just like fancy nail brushes only much cheaper!
  • Clean your cheese grater:  I hate trying to get the cheese grater clean, especially when my wash rag just gets stuck in those sharp little holes!
  • Let your kids get artistic:  Hand your kids an old toothbrush, some paint and some paper and see what sort of masterpiece they can come up with.
  • Garden markers:  Use a sharpie to write on the handle of your toothbrush and bury the ‘head’ in the soil. Now you know where your tomatoes are and which plants are your peppers!
  • Remove crayon marks from the wall:  Along with a bit of shaving cream, you can scrub crayon marks off the wall with your old toothbrushes.
  • Remove mud from the treads of sneakers: Instead of having your kids leave bits of dried mud all over the house, clean the soles of their sneakers with old toothbrushes.
