These Uses for Cornstarch Sound Ridiculous, but They Work

This post may contain affiliate links.

Cornstarch is usually thought of as nothing more than a cooking thickener, but it turns out this pantry staple can do much more than expected. Some of its uses sound a little odd at first, yet they genuinely work. From deodorizing and degreasing to simple household cleaning tasks, cornstarch quietly earns its place outside the kitchen. Below are some practical ways to put it to use.

1. Soothe Skin

A simple cornstarch paste can relieve minor skin irritations, such as sunburn. Mix cornstarch with water until it reaches a peanut butter-like consistency, then apply it to the affected area. Once dry, rinse off with water for a soothing effect.

2. Homemade Deodorant

Cornstarch can serve as a natural deodorant due to its moisture-absorbing properties. Combine melted coconut oil with cornstarch to create a cream, then add a few drops of your favorite essential oil for a personal touch.

3. Deter Fleas and Ticks

Cornstarch can be used to deter fleas and ticks from pets. Dust pet bedding and toys with cornstarch to create an inhospitable environment for these pests.

Sprinkle a little cornstarch on your hands before activities like tennis or gymnastics to absorb sweat and improve grip.

7. Dry Bath for Pets

Cornstarch is a convenient and gentle alternative for bathing pets when water is impractical or unnecessary. Use your hands or a brush to gently work the cornstarch through the fur, which helps to loosen and absorb dirt and oil.

After a few minutes, thoroughly brush out the cornstarch as you groom your pet. It will remove grime, leaving your pet’s coat clean, refreshed, and smelling better.

8. Polishing Silverware

Mix cornstarch with water to create a paste for polishing silverware. This eco-friendly cleaner restores shine without harsh chemicals.

9. Natural Fabric Starch

For those who prefer crisp lines and smooth fabrics, cornstarch is an excellent natural fabric starch that keeps materials crisp and neat-looking. Combine 1–2 tablespoons of cornstarch with two cups of water in a spray bottle, shake well, and lightly spray the mixture onto your clothes before ironing. It is particularly effective for shirts, table linens, and other fabrics that require a neat, tidy appearance.

10. Degrease Kitchen Surfaces

Use a cornstarch and water paste to remove greasy residues from kitchen walls and surfaces without harsh chemicals.

11. Carpet Freshener

To freshen carpets, sprinkle a liberal amount of cornstarch across the surface and let it sit for about 30 minutes. You can leave it set overnight for deeper odors if needed. Then simply vacuum the floor as usual to clean up the cornstarch.

As the cornstarch rests, it draws out dirt and odors from the carpet fibers. It’s an excellent alternative to chemical-laden carpet fresheners in homes with children and pets.

12. Cleaning Stuffed Animals

Cornstarch is gentle enough for cleaning and refreshing delicate items such as stuffed animals, plush toys, and delicate fabrics that may not withstand regular washing. Sprinkle a light layer of cornstarch on these items, then let it sit for a few minutes to absorb dust and slight odors. Afterward, use a soft brush or a damp cloth to gently remove the cornstarch, taking care not to saturate the fabric so it dries quickly.
