SENTINEL1 & 2: use mild soap and water to clean the ABS crown protector and never use bleach because it can degrade the plastic. A disinfectant can be used and will not damage the crown protector.
Acetate Visors: can be cleaned using disinfectant wipes and other agents such as peroxide type disinfectants. Acetate has a very strong chemical resistance so if in doubt try cleaning a small area of the visor before cleaning the entire visor.
Tritan Visors: have a lower chemical resistance than Acetate and can be cleaned as noted above. If in doubt, try testing a small area of the visor before cleaning the entire visor.
Polycarbonate Visors: polycarbonate has little to no chemical resistance and using mild soap and water work best. Be sure there is no lotion in the soap being used as this will cause streaking of the visor.
Polyester Visors (These visors are designed as single use)
