- Remove the shirt and lay it flat on a clean towel.
- Blot the stain with a paper towel to lift excess oil.
- Apply a dime-sized drop of dish soap directly to the stain.
- Use your fingertip to gently work the soap into the fabric in a circular motion for about 30 seconds.
- Let it sit for 10 minutes.

Step-by-Step for a Set-In Grease Stain on a Polyester Dress Shirt
Suppose you discover an old grease stain on a polyester dress shirt that has been through the dryer. Here is how to handle it:
- Lay the shirt flat and sprinkle a generous layer of baking soda over the stain.
- Let it sit for at least 30 minutes to absorb the grease.
- Brush off the baking soda with a soft brush.
- Apply dish soap directly to the stain and gently rub it in.
- Let it sit for 15 minutes.
- Rinse with cold water.
- Wash as usual, using the hottest water safe for the fabric.
- Check the stain before drying. If it persists, repeat the process.
Mistake to Avoid: Using Too Much Dish Soap
Using an excessive amount of dish soap can leave a sticky residue that attracts dirt and makes the stain worse. Use only a small amount, about the size of a dime, and rinse thoroughly after treatment.
Mistake to Avoid: Drying Before the Stain Is Gone
Heat from the dryer can set grease stains permanently. Always check the stain after washing and before drying. If any trace remains, treat it again and wash again.
Mistake to Avoid: Using Hot Water on Fresh Stains
Hot water can cause the grease to penetrate deeper into the fibers and set the stain. Use cold water for rinsing and washing fresh stains, unless the care label allows warm water.
When to Consult a Professional Cleaner
If the stain remains after three or more treatments, or if the shirt is delicate or has special care instructions, consider taking it to a professional cleaner. They have specialized solvents and equipment to handle stubborn grease stains without damaging the fabric.
FAQ
Can I use hot water to remove grease from a polyester shirt?
No, hot water can set the grease stain. Use cold water for rinsing and washing, unless the care label allows warm water. Always check the care label for the maximum temperature.
How do I know if the stain is completely removed?
After washing, inspect the stain while the shirt is still damp. If any grease remains, repeat the treatment before drying. Drying with heat can make the stain permanent.
What if the grease stain is old and set-in?
For set-in stains, apply baking soda and let it sit for at least 30 minutes to absorb the grease, then treat with dish soap. You may need to repeat the process several times. If it doesn't come out, consider professional cleaning.
Can I use bleach on a polyester shirt to remove grease?
No, bleach can damage polyester fibers and may not effectively remove grease. Stick to dish soap, baking soda, or enzyme-based stain removers, and always test on a hidden area first.
