We cannot say with certainty what type of dirt and debris may be on your product, or how certain cleaning products may react with it, but we have had good luck cleaning Razer products using commonly available monitor cleaning wipes.
To clean the body of your Razer headset, gently wipe it with a monitor wipe.
Do not scrub the surface of your Razer headset.
When cleaning the earpads, make sure that the ear cup and speaker do not get wet, as this can cause damage to your headset.
