Old, set-in stains require a bit more effort but can still be tackled with patience. First, heat can help re-liquefy the oil, making it easier to remove. Lay the garment on a flat surface and use a hairdryer to gently warm the stain. Be careful not to overheat, as this can damage the fabric.
Once warmed, apply a generous amount of cornstarch and let it sit overnight. In the morning, brush off the cornstarch and check the stain. If any residue remains, repeat the process or use a small amount of liquid dish soap directly on the stain, then launder as usual.
7. The Science Behind Why This Hack Works
Cornstarch is a polysaccharide composed of carbohydrate polymers. These polymers have a unique ability to absorb oils and fats. When applied to an oil stain, the cornstarch particles penetrate the fabric and latch onto the oil molecules. Over time, the cornstarch draws these molecules out, effectively lifting the stain from the fabric fibers.
This absorption process is what makes cornstarch so effective, as it essentially acts like a sponge, soaking up the oil without the need for water or harsh chemicals.
8. Common Mistakes That Make Oil Stains Worse
One common mistake is rubbing the stain, which can spread the oil further into the fabric fibers. Instead of blotting, people often instinctively scrub, thinking it will help remove the stain, but it often does the opposite.
Another mistake is applying heat too soon. Heat can set the stain deeper into the fabric, making it more challenging to remove. Always treat the stain first before washing or drying the garment.
9. Fabrics And Colors This Trick Works Best On
This cornstarch trick works best on natural fibers like cotton, linen, and wool. These materials have a looser weave, allowing the cornstarch to penetrate the fibers more effectively.
In terms of color, the method is safe for most fabrics, but always test a small, inconspicuous area first. While cornstarch is unlikely to cause discoloration, it's always wise to ensure that the fabric's colorfastness is intact.
10. When This Hack Won’t Work And What To Try Instead
There are instances where this hack might not be effective, such as on synthetic fabrics with tight weaves like polyester and nylon. In such cases, using a pre-treatment stain remover specifically designed for oil stains can be more effective.
If the stain persists, consider consulting a professional cleaner, especially for delicate or expensive items. They have access to industrial-strength solutions that can tackle even the most stubborn stains.
11. How To Prevent Oil Stains In The First Place
Preventing oil stains starts with being mindful in the kitchen. Wearing an apron while cooking can provide a protective barrier against accidental splashes. Also, consider using a splatter screen when frying foods.
For dining, be cautious with oily foods and use napkins liberally. If a spill occurs, address it immediately by blotting and applying cornstarch as soon as possible to prevent the oil from setting into the fabric.
