Grainger has contacted the product supplier and has been advised by them of the following:
Alcohol free wipes can be used on natural rubber, EDPM, and Silicone respirators without damaging. Alcohol based cleaners should not be used (or only used sparingly) with natural rubber or EDPM materials to prevent drying and cracking.
Silicone and non-silicone based solutions normally refer to lens cleaners. Silicone based cleaners are not suggested for Cleanroom applications.
All of the above can be used on silicone material face pieces.
Thank you for using Grainger Ask and Answer.
