How To Reuse a Toothbrush Instead of Throwing It Away

We’re supposed to replace toothbrushes about every three months, and at our house they quickly start adding up – good thing they’re good for more than scrubbing just your teeth. So, before you send them to be recycled, try using them in different ways around the house.

Definitely clean and disinfect the toothbrush so germs aren’t spread around. Also, be sure to label your ‘house’ toothbrush, so it doesn’t get mixed up with your ‘mouth’ toothbrush.

  • Toothbrushes are great for getting all the nooks in crannies around the house: around faucets and sinks, light fixture plates, windowsills, etc.
  • Instead of buying a grout scrubber, just use the toothbrush to clean the slim lines of grout – just don’t scrub too hard or it could cause damage.
  • Old toothbrushes are useful for cleaning tools, removing small oil/grease marks off tools/benches, etc.
  • Use to scrub thick skinned produce like potatoes, squash and other root vegetables.
  • Get in between all the knobs of a computer keyboard and monitor.
  • Use to clean bicycle chains.
  • Reuse as an eyebrow brush.
  • Use to clean cutlery – works great in between the tines of a fork.
  • Clean mud off the bottoms of shoes – a toothbrush is the perfect size to get in between treads.
  • Jewelry – a toothbrush works great on small scale objects like jewery and works itself easily into all the crevices of ornate jewelry. Pair the toothbrush with toothpaste for an extra shine!
  • Use on the fins of HVAC vents.
  • Gardeners will find a toothbrush handy to clean nails after gardening.
