Sani-Cide EX by Celeste Industries or minimum 70% isopropyl alcohol are preferred.   1. Sani-Cide EX3 produced by Celeste Industries 2. Matrix Disinfectant/Cleaner #3 produced by Jon-Don 3. NETBIOKEM DSAM produced by PSA 4. Isopropyl alcohol at least 70%.   Cleaning Procedure: Remove porous foam components such as ear cushions and foam microphone windscreen. Apply cleaning agent to a soft towel to clean the plastic and metal parts. Cleaner should wipe off or evaporate quickly. *Do not soak or allow the cleaner to puddle on the unit. *Do not allow any liquid to touch the speaker or microphone element directly as this may cause damage.
