How to Remove Grease Stains From Polyester & Poly Blends

Updated February 16, 2017

If you have recently purchased a suit, dress or blouse made of polyester or a poly blend, consider this cleaning fact: Fabrics constructed of these wrinkle-resistant fibres are durable and difficult to clean. With an absorbent powder and a cleaning solution, you can remove grease stains from polyester in a few simple steps. Learn how to face grease stains without fear, whether the machine washable fabrics are polyester or a poly blend.

Remove the excess grease on the top layer of the polyester fabric. Use a small white towel to blot the fabric. Do not scrub the fabric. Heavy scrubbing will cause the grease to seep into the lower layers of the fabric.

Dust the fabric lightly with an absorbent powder to soak up the grease. Apply baby powder or cornstarch over the stain. Allow the powder or starch to set for a minimum of 5 to 10 minutes. Shake the fabric lightly to remove the powder.

Create a paste of dishwashing liquid and baking soda. Using a toothbrush spread the mixture over the stained area. Scrub the stain lightly in a circular motion, on both sides of the item of clothing. Let the paste remain on the stain for 10 minutes.

Rinse the stain with cool water. Submerge the garment in a basin filled with cold water. Let the fabric sit in the water for 30 minutes

Wash the fabric in the washing machine. A cold water cycle is preferred, to clean the polyester fabric thoroughly.

Air-dry the fabric. Do not tumble in the dryer. A hot dryer will set the grease stain

If the stain remains, use 99 per cent isopropyl alcohol, a stain remover or a cleaning solvent to loosen the grease stain. Apply these solutions with a damp cloth, and press the cloth gently over the stain. Rinse with cold water, followed by a cold-water wash in the washing machine.


Use baby shampoo, as a dishwashing soap alternative, to create the paste in step 3. If the grease stain is the size of a quarter or smaller, use chalk instead of an absorbent powder to remove the grease stain. Using a small brush and light circular strokes, lift the stain from the polyester or poly blend fabric. According to the Environmental Protection Agency's website, "Rubbing chalk on grease stains before washing is a preferred cleaning product that aids in pollution prevention."


For fabrics that are dry clean only, do not attempt to pretreat grease stains with a cleaning solution. Blot the fabric with a white towel, and then take the garment to a professional for cleaning.
