Give Your Old Toothbrushes a New Lease of Life with These Handy Household Hacks
1. Faucet Cleaner
Old toothbrushes can be a great tool to clean faucets. Simply tie two toothbrushes together with a rubber band, dip them in water, and clamp the faucet between the brush heads. Gently scrub to effectively clean the narrow crevices where grime tends to build up.
2. Nut Cracker
Cracking nuts like pistachios, sunflower seeds, or peanuts with your hands can be a painful task. Try this instead: separate the bristles of the toothbrush slightly, tie two brushes back-to-back with a rubber band, and insert a folded piece of paper between them. Now you have a simple, handy, and strength-saving “nut cracker.”

3. Bicycle Chain Cleaner
Bicycle chains can get grimy with oil, dirt, and grime over time. To effectively clean the chain, tie two toothbrushes together so that the bristles face each other, then clamp the chain between them and pedal. This will quickly clean the chain without the need for disassembly.
4. Keyboard Cleaner
Keyboards are a haven for dust and bacteria. Use an old toothbrush to gently brush the surface and between the keys. In just a few minutes, your keyboard will be good as new.
5. Comb Cleaner
Combs are prone to collecting dandruff, excess oil, and dirt. Dip an old toothbrush into a soapy water solution or shampoo and brush the teeth of the comb. This method is both quick and effective.
6. Deep Bottle Cleaner
Mugs with deep bottoms or narrow-necked bottles can be challenging to clean. Simply heat the handle of the toothbrush, bend it into a 90-degree angle, and you’ve got yourself a handy tool to reach and clean those tough-to-access spots.
7. Toilet Bowl Cleaner
Toilet bowls often have small crevices and grooves that regular cleaning tools can’t reach. To tackle this, heat the handle of an old toothbrush, bend it into an L shape, add some cleaning solution, and start scrubbing those hard-to-reach areas—the results will amaze you.

8. Refrigerator Seal and Window Frame Cleaner
The rubber seals on refrigerator doors or window frames attract dust but are tricky to clean. Using a bent toothbrush will allow the bristles to reach deep into the grooves, effectively cleaning them without applying excessive force.
9. Crayon Wall Stain Remover
If you have young children, you’ve likely dealt with crayon stains on your walls. Worry not! Simply apply some shaving cream or toothpaste to an old toothbrush, gently scrub the stain, and wipe it away with a clean cloth. Your wall will look as good as new.
10. Jewelry Cleaner
Small jewelry items like rings, necklaces, or earrings can accumulate dust and grime in their crevices. To clean them, soak an old toothbrush in a mild cleaning solution and gently scrub the jewelry’s surface. Your jewelry will shine like new without the need for specialized equipment.
