To clean the facepiece
1 Remove the mask-mounted regulator from the facepiece docking port.
2 If the facepiece is heavily soiled, you may have to first wash the facepiece with a solution of mild soap or
detergent in warm water (110° F / 43° C maximum).
• Using a spray bottle, apply a solution of mild soap or detergent in warm water (110° F / 43° C maximum) to the
soiled surfaces. Rinse the facepiece with drinking water either from a faucet or in a spray bottle.
-OR-
• Clean the facepiece using 3M 504 Respirator Cleaning Wipes.
3 To sanitize and/or disinfect the facepiece, use a spray bottle to apply the appropriate sanitizing and/or
disinfecting cleaner to all surfaces. Be sure to cover all surfaces completely with the solution.
4 Set the facepiece aside for the required contact time prior to rinsing. The hypochlorite solution and the aqueous
solution of iodine require a 2-minute contact time.
5 Rinse the facepiece with drinking water either from a faucet or in a spray bottle.
6 Shake excess water off the facepiece and dry it with a clean, lint-free cloth or gently blow dry with clean, dry
breathing air of 30 psig or less pressure. Do not use shop air or any other air containing lubricants or moisture.
NOTE
When cleaning the facepiece, do not use the following cleaning products:
• Abrasive cleaners
• Bleach stronger than a 3% solution in water
• Solvents such as acetone, paint and lacquer thinner, benzene, or dry-cleaning fluid
In addition, do not do the following:
• Polish with paper towels as most paper contains abrasives
• Autoclave or wash in an unapproved automatic washer
• Use a vapor degreaser/polisher
TIP
A nosecup is designed to be an integral part of the facepiece and does not need to be disassembled for
cleaning unless the facepiece is heavily soiled.
NOTE
The Kevlar head harnesses are made of porous material. The recommended cleaner may not be effective on
porous material.
