Used toothbrushes, which most people consider trash, have a surprising number of practical uses. By simply tying two old toothbrushes together, you can solve a variety of cleaning and household challenges in an easy and cost-effective way.

Clean Household Faucets

To clean faucets, take two old toothbrushes and secure them together with a rubber band. Dip them in water, then open the brushes slightly and scrub around the faucet. The narrow gap around the base of the faucet is often difficult to reach, but two toothbrushes working together make the job much easier.

Create a Tool for Opening Hard-Shelled Nuts

Cracking nuts by hand can be tiring and uncomfortable. To make the process easier, trim the bristles of two old toothbrushes, place them facing each other, and tie them together with a rubber band. Insert a folded piece of paper between them to create tension. You now have a simple tool for opening pistachios, peanuts, sunflower seeds, and other hard-shelled nuts.

Clean a Bicycle Chain

Bicycle chains often collect a mixture of oil and sand, which adds weight and shortens the chain’s lifespan. To clean it, tape two old toothbrushes together with the bristles facing inward. Place the chain between the brushes and rotate the pedals. This allows you to clean the chain quickly and effectively.

Dust Your Keyboard

Computer keyboards easily accumulate dust over time. Simply use an old toothbrush to brush between the keys, and the dust will come off with minimal effort.

Clean Hair Combs

Hair combs are used every day and can collect sweat, dirt, and dandruff. Dip an old toothbrush into water mixed with a small amount of detergent, then scrub along the teeth of the comb. Stubborn buildup will be removed in no time.

Scrub the Bottom of Cups

The bottom of cups, especially those with narrow openings, can be difficult to clean. Heat the back of an old toothbrush head and bend the handle to a 90-degree angle. This creates the perfect tool for scrubbing deep cups, bottles, and jars.

Reach Hidden Corners of the Toilet

Toilets have tight spaces that are hard to clean with ordinary tools. Warm the inside of an old toothbrush handle over a flame and bend it into an L shape. Apply toilet cleaner and use the brush to scrub hard-to-reach areas with ease.

Clean Refrigerator Seals and Window Frames

A bent toothbrush is also ideal for cleaning the narrow grooves of refrigerator door seals and window frames—areas that tend to collect dust but are difficult to wipe thoroughly.

Remove Crayon Marks from Walls

To erase crayon marks, apply a small amount of shaving cream or toothpaste to an old toothbrush and gently scrub the stained area. Once the marks disappear, wipe the wall clean with a cloth.

Clean Jewelry

Jewelry often contains tiny grooves and crevices that are difficult to reach. Dip an old toothbrush into a cleaning solution and gently scrub the surface. Dirt and residue will be removed quickly and effectively.
