BANOX FR3, BANOX CERTIFIED AND BANWEAR flame resistant garments can be laundered under conditions normal for 100% cotton flame resistant garments.  All can be dry-cleaned.  BANOX CERTIFIED AND BANWEAR flame resistant treatment will last for the usable life of the garment if the care and maintenance recommendations are followed as outlined.
BANOX FR3, BANOX CERTIFIED AND BANWEAR RECOMMENDATIONS FOR CARE AND MAINTENANCE
INDUSTRIAL LAUNDRY
The Laundering procedure described in ASTM document F1449-01 for flame resistant cotton garments is recommended for BANOX FR3, BANOX CERTIFIED AND BANWEAR fabrics. 

With hard water and high temperature industrial laundering and drying, minerals can build up on flame resistant fabrics containing cotton and make them flammable at a rate which depends upon the laundering conditions and hardness of the water.  High levels of mineral buildup can be prevented by use of soft water or an adequate sour.  Laundries using had water or wash conditions different from F1449-01 should test the flammability of these fabrics after 100 washes using the vertical flame method described in ASTM D6413.
INDUSTRIAL DRYING
Fabric temperature should not exceed 280°F during the drying process.  normal shrinkage of up to 5% can occur so garments whould be fitted with this in mind.
HOME WASH
All detergents, except those containing chlorine or peroxide bleach and enzymes, sold for home use may be used.  Hardness of the water does not affect BANOX FR3, BANOX CERTIFIED AND BANWEAR fabric flammability using home wash detergents and wash conditions provide that fabrics are adequately rinsed.
