Got pests like mealybugs or dust building up on your houseplants? A soft-bristled toothbrush is gentle enough to clean leaf undersides, stems, and buds without causing damage.
Just dip it in water or a mild soap solution and gently brush away the grime.
It’s especially helpful for delicate indoor plants where your fingers might be too rough. Try brushing in the morning so the plant has time to dry out.
#2 Plant Marker

Turn your old toothbrush into a quirky plant label. Just write the plant’s name on the handle with a permanent marker or tape a small waterproof label to it. Stick the brush handle-first into the soil for a fun, eco-friendly marker.
It’s a simple way to reuse materials and add charm to your garden beds or containers.
#3 Make Holes For Seeds

Poking holes for seeds doesn’t have to get your fingers dirty. Use the back end of a toothbrush to make perfect little seed holes in soft soil.
This trick works especially well in seed trays or small pots. Keep one toothbrush just for this task so it’s always within reach.
#4 Clean Dirt Off Veggies and Fruits

Gently remove soil and grit from freshly harvested produce using your old toothbrush. The bristles work wonders on root veggies like carrots, radishes, or even mushrooms.
Rinse them under cool water while scrubbing for the best result. Just make sure the brush is clean and used only for food.

Don’t let grime build up on your favorite garden gear. Use an old toothbrush with a little soap or vinegar to get into tight corners of pots, pruning shears, or watering cans.
It’s perfect for cleaning off dried soil or rust from tools with grooves and hinges. A quick brush-down after each use can keep tools in good shape.
#6 Make Glass Bottles and Vases Cleaner

Ever struggle to clean the narrow neck of a vase or bottle? A toothbrush can reach inside spots your hand can’t. Pair it with dish soap or baking soda for tough stains.
This is super useful if you reuse glass bottles for plant cuttings or homemade plant food.
#7 Help in Pollinating Tomatoes and Peppers

If bees aren’t doing the job, you can! Use a toothbrush, especially an old electric one, to gently vibrate tomato or pepper flowers for hand-pollination.
Hold it just behind a flower cluster and buzz for a few seconds to mimic a bee’s vibration. This method can improve fruit set and give you a better harvest.
#8 Apply Neem Oil

Want to treat a few leaves without dousing the whole plant? Dip your toothbrush into a neem oil or insecticidal soap mix and gently brush it onto infected areas.
This helps target pests like aphids or mildew without overwhelming your plant. It’s a precise, no-mess way to apply treatments.
#9 Brush Corns

After husking fresh corn, those silky threads can be hard to get rid of. A toothbrush makes it easy to brush them away quickly and gently.
Just give the cob a few light swipes under running water. It’s way more effective (and satisfying) than trying to pick them off by hand.
#10 Clean Your Nails

Dirty nails from digging in the soil? Keep an old toothbrush by the sink to scrub the grime out from under your nails.
Use warm soapy water and gentle strokes for clean hands in no time. It’s a small touch that makes post-gardening cleanup so much easier.
