Don't throw away old toothbrushes, they can be extremely useful for cleaning hard-to-reach places and hard-to-reach items in your home.
You don't need expensive or specialized tools to get your house sparkling clean. Sometimes the best cleaning supplies are right in your pantry (like vinegar and baking soda) or even on your bathroom counter —like that old toothbrush you were about to throw away. Thanks to its soft nylon bristles and compact size, this toothbrush can be incredibly effective at cleaning those crevices or stubborn stains.
Brick mortar
Tile grout is notoriously difficult to clean, and simply spraying a cleaning solution and wiping it down with a cloth or sponge often doesn't do the trick. However, an old toothbrush can get into the crevices and scrub away stubborn stains. Sure, it can be tedious, but you'll see your tile grout get clean.
Jewelry
A toothbrush allows you to gently clean between stones and brush away any built-up dirt. Just avoid using any abrasive cleaners or harsh detergents on your jewelry, as these can scratch the metal and gemstones.
Stains on clothes
You may have been told never to scrub stains on your clothes, but some stains are really stubborn. The combination of an old toothbrush—along with a vinegar solution, detergent, or baking soda—can work wonders. It loosens and lifts stubborn, hard-to-remove stains like grease from your clothes.
Shoe
Not all shoes can or should be put in the washing machine. In that case, an old toothbrush can be especially useful for tackling stains or marks, brushing away accumulated dirt, and even removing those pesky stones stuck in the soles of your shoes.
Carpet stains
Depending on the size of the stain, a toothbrush can also be an effective tool for scrubbing stains out of carpets or upholstery. Just be sure to always test the cleaning solution in an inconspicuous area first, to avoid accidentally making it worse.
Brassware
Brass is susceptible to tarnish and needs regular polishing to keep it looking new. If you have stubborn stains on your brass, toothpaste can help. Apply a little to the stain and scrub gently with a toothbrush, then rinse to keep your piece looking like new.
Washing machine
A toothbrush is really too small to clean an entire washing machine. However, a toothbrush can be very useful when cleaning the gasket, drawer, or filter on a front-loading or top-loading washing machine.
