How to Remove a Grease Stain from a Polyester Shirt
A grease stain on a polyester shirt can leave a dark, oily mark, but you can lift it with dish soap and baking soda. Here's a practical guide for fresh and set-in stains, with polyester-specific precautions.
Part 2: Step-by-step method
If the stain has dried or been through the dryer, it's set in but still removable. Here's what to do:
- Apply dish soap to the stain and let it sit for 15–20 minutes.
- Make a baking soda paste by mixing three parts baking soda with one part water. Apply it over the dish soap and gently rub it in.
- Let it sit for another 15–20 minutes. The baking soda helps absorb and lift the grease.
- Rinse with warm water and check the stain. If it's still visible, repeat the process.
- Wash and air dry as before.
What Not to Do
Avoid these common mistakes:
- Don't use hot water on a fresh grease stain, as it can set the stain.
- Don't put the shirt in the dryer until the stain is completely gone. Heat can permanently set grease stains.
- Don't rub the stain aggressively, as this can damage polyester fibers.
- Don't use bleach on polyester unless the care label specifically allows it, as it can cause yellowing.
Fresh vs. Dried Stains
Fresh grease stains are easier to remove because the oil hasn't had time to bond with the fabric. Dried stains require more effort and a longer soaking time. If the stain has been through the dryer, it may be more stubborn, but the baking soda method can still work. Always check the stain before drying, and repeat the treatment if necessary.
