Nylon and polyester fibers are tough and durable clothing materials. That does not mean they are stain proof. Oil stains are particularly difficult to remove, but like other types of stains on nylon and polyester, they can be removed if cleaned right away. Commercial cleaning solvents are best for getting stains out, followed by regular laundering.

Wipe gently or blot any excess liquid from the cloth. Do not rub as that can make the stain spread.

Test the cleaning solvent or spot solution on a hidden seam to see if it affects the color or finish of the clothing. If it doesn’t, place a clean pad or cloth on a stable surface.

Put on gloves and place the stained item stain-side down on the cloth. Pour some cleaning solution on the sponge and dab the sponge on the backside of the stain. The stain should be pushed to the clean cloth underneath.

Move the stained portion to a clean area of the cloth or pad underneath and repeat the dabbing process, pushing the stain to the cloth or pad underneath. Place your gloved hand under stain with the stain facing you. Dab the stain with the cleaning solution-soaked sponge.

Toss the stained item directly into a regular wash. Inspect it after washing to ensure the stain is gone. If it is, dry the article of clothing. If not, repeat the process until the stain is gone.
