Garment Care
Garments of NOMEX can be cleaned by home or commercial laundry or by dry cleaning procedures without loss of their outstanding protective features. The following suggestions will help you keep your garments looking neat and attractive.
Laundering
• Pre-treat greasy stains and collar/cuff lines with a product such as Spray ‘N Wash or Shout.
• Launder garments of NOMEX only with other garments of NOMEX to help avoid surface entrapment of flammable lint and to minimize static in the tumble dryer.
• Do not overload home laundry equipment. Wash garments in warm water with a mild detergent such as Era, Tide, Cheer, Woolite, etc. ( no bleach) .
• For maximum fire protection, greases and oils should be thoroughly removed from garments of NOMEX after each wearing. If home procedures do not accomplish this, commercial laundering or dry cleaning is recommended.
• Always fasten Velcro (collar and belt) to prevent fraying.
