Starching Clothes (How To Starch Clothes At Home) - Oh So Spotless

Want that sharp, professional look without the steep dry cleaner bill? Starching your clothes is the secret weapon you need. It adds a crisp edge to shirts, dress pants, and linens that standard ironing just can’t match.

You don’t need fancy equipment to pull this off. We will walk you through exactly how to starch clothes at home, the difference between starch and sizing, and the mistakes you need to avoid to keep your wardrobe in top shape.

Key Takeaways

• Starching adds a crisp finish, resists wrinkles, and protects fibers from dirt.
• Use spray starch for natural fibers like cotton and linen; use laundry sizing for synthetics.
• Avoid starching delicate fabrics like silk, wool, cashmere, or wool blends.
• For best results, iron without steam and hang the garment immediately to dry.

What Does Starch Do to Clothes?

Before you start spraying, it helps to know the science. Starch is a plant-based compound (usually from corn, wheat, or rice) that stiffens fabric fibers. Think of it as a temporary shield. It fills in the gaps between fibers to make the surface smooth, stiff, and wrinkle-resistant.

However, it is not a magic solution for everything. Here is the breakdown of why you should (or shouldn’t) use it.

Advantages:

• Polished look: It gives clothing that satisfying, crisp snap you usually only get from a professional service.
• Stain protection: Dirt and sweat stick to the starch rather than the fabric fibers, which makes washing stains out much easier.
• Easier ironing: The iron glides smoother, and ironing becomes faster because the heat sets the shape quickly.
• Longevity: You can often get up to three wears out of a starched item before it needs a wash.

Disadvantages:

• Comfort: Heavy starching can make clothes feel scratchy or stiff against the skin.
• Fabric wear: Over-starching without washing in between can eventually break down fibers, reducing the lifespan of the garment.

How to Starch Clothes

You could pay a professional, but doing it yourself is simple and cost-effective. Here is how to get that military-grade crispness in your own laundry room.

What You Need

• Spray starch (essential for cotton or linen).
• Laundry sizing (essential for polyester or cotton-blends).
• Sturdy ironing board.
• Steam iron.
• Quality hangers.

Step by Step Instructions

1. Prep the garment: Start with a clean item. Never iron a dirty shirt, as the heat will permanently set stains.
2. Set the stage: Place the garment flat on your ironing board. If you have a heat-reflective cover, it speeds up the process.
3. Apply the product: Spray your starch (for naturals) or sizing (for synthetics) evenly across the area you are about to iron. Don’t soak it; a light mist is usually enough. Let it sit for a few seconds to penetrate the fibers.
4. Iron carefully: Check the care label for heat settings. Turn off the steam function on your iron. You want dry heat to crisp up the starch liquid. Press firmly but keep the iron moving to avoid scorching.
5. Hang immediately: Once you finish a section or the whole garment, hang it on a hanger right away. This allows the starch to fully cure and set the shape as it cools.

What Not to Starch

Starch is fantastic for cotton button-downs, but it is a disaster for delicate fibers. The granular nature of starch can ruin specific textures (1).

Avoid starching these materials:

• Silk (it creates spots).
• Wool.
• Cashmere.
• Wool-blends.
• Delicate synthetics (like Rayon).

Note on Synthetics: Durable synthetics like polyester or nylon shouldn’t be starched with corn-based products. Instead, use laundry sizing. Sizing adds body and removes static without damaging the plastic fibers of synthetic cloth.

Pro Tips for Best Results

Want to starch like a pro? Keep these tips in mind to protect your clothes and your iron.

• Clean your iron: Starch can build up on the soleplate of your iron over time. If your iron starts dragging or leaves white residue, clean the plate with a specialized cleaner or a vinegar solution.
• Watch for buildup: If you use heavy starch, you must wash the garment thoroughly between starchings. Layering fresh starch over old starch causes yellowing and flaking.
• Storage warning: Never store starched clothes for long periods (like off-season storage). Starch is food-based and can attract silverfish and other bugs (2). Wash the starch out before putting items in the back of the closet.
• DIY Solution: Out of spray? Mix 1.5 tablespoons of cornstarch with 2 cups of water. Shake well and put it in a spray bottle. It works just as well as the store-bought versions for a fraction of the price (3).
• Batch your work: If using liquid starch in the washer (for a whole load), pour 1.5 cups into the rinse cycle. Iron the garments while they are still slightly damp for the best finish.

FAQs

Got more questions about crisping up your collars? Here are the answers.

Is Starch Bad for Your Shirts?

In moderation, no. It actually protects them from dirt and oil stains. However, excessive starching without washing can make fibers brittle, causing them to fray faster at the creases (like cuffs and collars). Wash your shirts frequently to rinse out old starch.

What Is the Difference Between Starch and Sizing?

Starch is made from vegetable products (corn, wheat) and is best for natural fibers like cotton and linen. Sizing is a resin-based solution designed for synthetic fibers (polyester, nylon) or blends. Sizing restores the original “hand” of the fabric and reduces static without making the item stiff.

Should You Starch Dress Pants?

Yes, starch helps dress pants hold a sharp crease. However, check the tag first. If they are wool or a wool blend, do not starch them. If they are synthetic, use laundry sizing instead to avoid damaging the sheen of the fabric.

Does Starch Wash Out of Clothes?

Yes. Since commercial starch is water-soluble, it dissolves easily in a standard wash cycle. Simply follow the care label instructions on your garment, and the starch will rinse away completely.

Do You Let Starch Dry Before Ironing?

No, you don’t need to let it fully dry. Spray the section you are working on, let it soak in for just a few seconds, and then iron immediately. The heat of the iron dries the liquid and sets the crisp finish simultaneously.

Can You Put Liquid Starch in the Washing Machine?

Yes. Adding liquid starch to the fabric softener dispenser during the rinse cycle is a great way to starch a whole load of linens or shirts at once. Just ensure you iron them while they are slightly damp or hang them to dry immediately.

Does Starching a Shirt Prevent Wrinkles?

Absolutely. Starch creates a stiffer fabric structure that resists bending and creasing. While it won’t make a shirt permanently wrinkle-proof, it will keep you looking fresh throughout a workday much better than an un-starched shirt.

How Do You Starch Black Clothes?

Starching dark clothes can sometimes leave flaky white residue. To avoid this, turn the garment inside out and spray the starch on the interior side. Iron the inside of the fabric. This keeps the visible side crisp and streak-free.

Can You Starch Your Clothes in the Dryer?

No. Putting starched clothes in a dryer is a bad idea. The tumbling action breaks the starch bond, rendering it useless, and the high heat can cause the starch to flake off or melt into the fabric unevenly. Always air dry starched items.

Look Sharp, Feel Sharp

Starching is a small extra step that makes a massive difference in your presentation. Whether it is a job interview or just a Tuesday at the office, a crisp shirt commands respect.

Just remember the golden rules: match the product to the fabric (starch for cotton, sizing for synthetics) and keep that iron steam-free. Now go give those wrinkled shirts a professional makeover!
