How often should I wash my FR clothing?  

In general, FR clothing should be washed after each use to remove dirt, grime, and other contaminants that can affect its flame-resistant properties. It’s important to follow the manufacturer’s care instructions, as different FR fabrics may have different care requirements. 

In some cases, FR clothing may be able to be worn multiple times before washing, but this will depend on the conditions in which it is being worn and the specific type of FR fabric used. If the FR clothing becomes soiled or shows signs of wear and tear, it should be washed and replaced as necessary.
