How to Clean an Armpit Smell From Polyester

Everybody perspires and is susceptible to leaving foul-smelling body odor on his or her clothing. Perspiration is generally more profuse when working out and performing manual labor. Although resistant to mildew and wrinkles, polyester is vulnerable to armpit odor. Perspiration stains often accompany armpit odor, which doubles the embarrassment. The key to eliminating armpit odor from polyester is to clean the garment promptly, before the odor fully permeates the polyester. Clean an armpit smell from polyester by using basic cleaning agents.

Armpit odor becomes harder to extract from polyester shirts over time.

Step 1

Squirt white vinegar onto the underarm region of the polyester shirt, saturating the smelly area. Let the vinegar-dampened polyester air-dry.

Step 2

Smell the underarm area of the polyester shirt to determine if the odor is gone. If the odor lingers, coat the affected polyester liberally with pre-wash stain remover.

Step 3

Rub the pre-wash product into the polyester. Let the product permeate the polyester for 15 minutes.

Step 4

Rinse the polyester shirt thoroughly in warm water.

Step 5

Launder the polyester shirt in the washing machine with warm water and 2 ounces of enzyme-based laundry detergent.

Step 6

Dry the polyester shirt in the dryer, using the tumbling cycle.
