Versatile Cornstarch Uses for Home & Kitchen

Did you know that cornstarch, commonly used as a thickening agent, has a range of surprising uses beyond the kitchen? From helping with laundry to personal care and even household tasks, cornstarch proves to be a versatile and handy ingredient that can simplify your daily life.

Why I Love These Cornstarch Uses

Though most of us find a box of cornstarch in our pantry for cooking, it’s also phenomenal for multiple uses around the homestead. Anytime an ingredient or product has multiple uses, it’s a win-win in my book. This makes buying in bulk more reasonable, knowing I’ll use up the product before it goes bad.

What Is Cornstarch

Before we delve into the numerous uses of cornstarch, it’s important to understand what cornstarch actually is. Cornstarch is a fine and powdery substance that is derived from the endosperm of corn kernels.

It is commonly used as a thickening agent in cooking and baking due to its remarkable ability to absorb moisture. It can also help achieve a smooth, velvety texture in various dishes such as cream of chicken soup, hearty pot roast cottage pie, ground beef curry, or a basic pan sauce.

Cornstarch is a staple ingredient in many kitchens around the world, and its versatility extends far beyond its role in thickening sauces and gravies. Its unique properties make it an indispensable ingredient in a wide range of culinary applications.

Cornstarch vs. Cornflour

It is important to understand the key differences between cornstarch and cornflour. While cornstarch is made from the endosperm (or the starch portion) of corn, corn flour is made from the entire kernel. Because cornflour contains starch and protein, it will not have the same results in cooking and household applications.

Therefore, cornflour should not be substituted for cornstarch in recipes or for household hacks.

Substitutions for Cornstarch

If cornstarch is not suitable for your specific needs, there are alternatives you can consider. These alternatives probably won’t have ideal results for the majority of household purposes, but they will work as a gluten-free flour option and as a thickening agent in recipes.

  • Tapioca Starch – Unlike cornstarch and cornflour, tapioca starch and tapioca flour are used interchangeably. Tapioca does not have the same thickening power as cornstarch, so twice as much should be used in recipes for this application.
  • Potato Starch – Potato starch has the same thickening power as cornstarch and can be substituted 1:1 in recipes. However, it’s important to note that if overheated, potato starch can lose its thickening ability.
  • Arrowroot Powder – Arrowroot powder has the same thickening power as cornstarch, and can be substituted 1:1 in recipes. However, arrowroot powder is a significantly more expensive alternative than using tapioca or potato starch.

Cornstarch Uses for Laundry

When it comes to laundry, cornstarch can be a valuable ally in tackling common challenges. Its versatility extends beyond cooking and baking, making it a useful addition to your laundry routine.

TaskCornstarch Solution
Scorch MarksIf you accidentally use too high of a setting on your iron and scorch your fabric, simply spritz the area with water, sprinkle with cornstarch and allow it to dry. Then, brush the dried cornstarch away to reveal the refreshed fabric.
Stains on clothingCreate a paste with cornstarch and warm water, apply it to the stain, and let it sit before washing. For a grease stain, sprinkle cornstarch on dry so that it can absorb the grease. Allow it to sit for at least 15 minutes before brushing off the cornstarch from your garment and washing it as normal. Remember to always test the cornstarch paste on a small, inconspicuous area of the fabric before treating the stain to avoid any unwanted discoloration or damage.
DIY Starch SprayAdd one tablespoon of cornstarch to a 16 oz. spray bottle. Fill with warm water and shake until combined. Spritz on clothing prior to ironing for an all-natural starch spray.

Freshen CarpetsIf you’re looking to freshen up your carpets, cornstarch can come to the rescue. Sprinkle a thin layer of cornstarch over your carpets, focusing on any areas with odors or moisture. Let it sit for a few minutes to absorb unwanted smells, and then simply vacuum it up. Your carpets will be left feeling and smelling fresh.
Deodorize ShoesCornstarch works well to absorb odors in smelly shoes. Just sprinkle the offending shoe with cornstarch and allow it to sit for at least 12 hours. Shake out the cornstarch before the next wear.
UpholsteryUsing equal parts cornstarch and baking soda, add just enough water to make a paste. Apply to upholstery and allow to dry. Vacuum as normal.
KnotsSprinkling cornstarch on knots in necklaces, shoelaces, and strings helps to loosen them with ease.
DogsKeep your dog’s hair smelling and looking fresh in between groomings by sprinkling their coats with cornstarch and brushing through.
Furniture PolishIf you struggle to remove furniture polish residue after polishing your heirloom pieces, don’t fret. Just sprinkle a little cornstarch on the piece and buff it with a clean cloth. The cornstarch will absorb the excess, leaving a beautiful shine behind.
Polish SilverwareWhen your silverware starts to lose its shine, reach for cornstarch. Create a paste by mixing cornstarch with a small amount of water. Gently rub this paste onto your tarnished silverware using a soft cloth or sponge. Rinse off the paste and dry your silverware thoroughly, and you’ll be amazed at the renewed sparkle.
Carpet StainsIf you have an ink, wine or blood stain on your carpet, try mixing just enough milk with cornstarch to make a paste. Apply it to the stain and allow it to dry completely. Finish by vacuuming as normal.
Driveway StainsPut a liberal amount of cornstarch on driveway stains and allow it to sit overnight to absorb the stain. Wash it away the next day with a garden hose.
WindowsIf you don’t have this DIY window cleaner on hand, try adding a gallon of warm water to a bucket with one teaspoon of cornstarch and one teaspoon of dish soap. Dip a rag into the solution, and clean your windows. Follow behind with a dry microfiber cloth to make them shine.
Finger PaintsHands-on projects like making this edible playdough recipe are a great way for children to learn while they are having fun. To make fingerpaints mix together ¼ cup of cornstarch with two cups of cold water in a saucepan and bring to a boil until the mixture thickens. Pour “paint” into several different cups of a muffin tin and color using food coloring.
DIY SlimeAnother great hands-on project for your little ones is to make slime or “Oobleck.” Just mix together one part water (colored with food coloring of choice) with two parts cornstarch, and marvel as the substance acts as a solid when pressed but returns to liquid when you let go.
Freshen Stuffed AnimalsIf your stuffed animals or plush toys start to accumulate moisture or unwanted odors over time, cornstarch can come to the rescue. Simply sprinkle a small amount of cornstarch on the toys, allowing it to absorb excess moisture and eliminate unpleasant smells. After a few minutes, gently brush off the cornstarch residue, and your stuffed animals will be revitalized and ready for more cuddles.
