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. Use only isopropyl alcohol (70% minimum) on porous foam parts including the mic windscreen and/or ear cushion. Once removed soak until absorbed completely. Squeeze out excess liquid and allow to air dry at room temperature before reattaching. Cleaning directions included in this letter are for external surfaces only.
