Old toothbrushes may look useless, but with a little creativity, they can turn into powerful household helpers. By simply tying two old toothbrushes together, you can create clever DIY tools that solve everyday cleaning and maintenance problems—without spending extra money on fancy gadgets.

1. Clean Hard-to-Reach Faucet Areas
Tie two toothbrushes with their bristles facing each other using a rubber band. Dip them in water and scrub around the tight crevices of your faucet. This dual-bristle setup easily clears grime, calcium, and soap buildup.
Pro Tip: Add vinegar or dish soap for extra cleaning power.
2. DIY Nut Cracker for Hard Shells
Remove the bristles from two toothbrushes and tie the handles together, inserting a folded piece of paper or soft cardboard between them. This makes a simple squeezing tool to crack pistachios, peanuts, or sunflower seeds—saving your fingers from strain.
Bonus Tip: Perfect for kids or seniors with weaker hand strength.

3. Clean Bicycle Chains Efficiently
Secure two toothbrushes with the bristles facing inward. Place your bike chain between them, then rotate the pedals. The brushes scrub both sides at once for a deeper, faster clean.
Maintenance Tip: Always reapply light lubricant afterward to keep your chain running smoothly.
4. Clean Your Computer Keyboard
A single toothbrush works wonders for dust and crumbs stuck between keys. For stubborn grime, dampen the brush with a bit of rubbing alcohol (not too much).
Extra Tip: Use compressed air or a mini vacuum afterward for a spotless finish.
5. Clean Hairbrushes and Combs
Dip a toothbrush in warm, soapy water or diluted shampoo and scrub between the bristles of your hairbrush. This removes trapped oils, dandruff, and buildup, keeping your brushes fresh and hygienic.
6. Scrub Narrow Cups, Bottles, and Vases
Heat a toothbrush handle over a flame (carefully!) and bend it to a 90-degree angle. This new shape makes it easy to scrub deep into bottles, thermoses, and vases.

7. Clean Hidden Corners of the Toilet
Bend an old toothbrush into an L-shape and add toilet cleaner to the bristles. Use it to scrub under the rim and around bolts—places most toilet brushes can’t reach.
Sanitary Tip: Disinfect thoroughly or discard after use.
8. Reach Window Tracks and Fridge Gaskets
Dust, crumbs, and mold often build up in these narrow spaces. Spray some all-purpose cleaner and scrub with a bent toothbrush to restore freshness.
9. Remove Crayon Marks from Walls
Apply a little toothpaste or shaving cream to a toothbrush and gently scrub over crayon marks. Wipe clean with a damp cloth—no wall damage in most cases.
10. Polish Jewelry and Delicate Items
Jewelry has tiny grooves where dirt loves to hide. Dip a toothbrush in mild soap or a jewelry-cleaning solution, then scrub gently. This works for rings, watches, and even eyeglass frames.
Safety Note: Avoid harsh cleaners on pearls, opals, or other soft gemstones—just mild soap and water.
