Old toothbrushes may seem useless, but they actually have many surprising and unexpected uses. By simply tying two toothbrushes together, you can easily and cost-effectively tackle various household problems.

Clean Faucets

Take two old toothbrushes and use a rubber band to bind them together so that the brush heads face each other. Dip this makeshift tool into water and scrub the crevices of your faucets. This method allows you to easily clean hard-to-reach areas without needing specialized tools.

Create a Hard-Shelled Nut Cracker

Cracking nuts like pistachios, peanuts, or sunflower seeds by hand can be time-consuming and painful. Simplify the process by removing the bristles from two old toothbrushes and binding them together with the brush heads facing each other, using a rubber band. Place a folded piece of paper in between the brush heads. This tool will help you crack nuts more easily and efficiently, without hurting your hands.

Clean Bicycle Chains

Bicycle chains often get caked with dust, dirt, and grease, which can hinder performance and reduce the lifespan of the chain. Bind two old toothbrushes together so that the bristles face inward, then place the chain between them. Pedal the bicycle to make the chain slide through the bristles, effectively removing all the grime.

Clean Computer Keyboards

Computer keyboards can accumulate dust and dirt over time. Simply use an old toothbrush to gently brush between the keys to dislodge the dust without having to dismantle the keyboard.

Clean Hairbrushes

Hairbrushes tend to get clogged with hair, oil, dust, and dandruff. Dip an old toothbrush into a diluted soap solution or a mild cleaning solution and brush along the teeth of the hairbrush. This method quickly cleans the brush, helping to maintain the hygiene of your hair and scalp.

Clean Narrow-Necked Bottles and Jars

Bottles and jars with deep bottoms and narrow necks are usually difficult to clean with regular tools. Heat the head of an old toothbrush and bend it at a 90-degree angle. This modified brush will now effectively scrub the bottoms and corners of bottles, jars, and containers.

Clean Toilet Corners

Some small, hidden areas of the toilet are often missed during cleaning. Heat the handle of an old toothbrush and bend it into an L shape. Apply a cleaning solution to the brush and use it to scrub every nook and cranny of the toilet, ensuring a thoroughly clean space with no “dead corners.”

Clean Fridge Seals and Window Frames

Narrow crevices, such as rubber fridge seals and window frames, tend to accumulate dust and dirt and are difficult to clean. With the bent toothbrush, you can easily reach into these tight spaces and effectively remove the built-up grime.

Remove Crayon Marks from Walls

If you have young children, your walls may be decorated with crayon art. Apply some toothpaste or shaving cream to an old toothbrush and gently scrub the marks. Once the crayon marks fade, wipe the wall with a clean cloth, and it will look as good as new.

Clean Jewelry

Jewelry often has small crevices that are difficult to clean by hand. Simply dip an old toothbrush into a specialized cleaning solution and gently scrub to quickly remove dirt and restore the shine to your jewelry.
