I do a cleaning on all my peripherals once every 4 months. I have an Asus TUF gaming h3 headset and every time I clean the cushions, it will always feel like its wet with oil and grease even if I already had washed it and wiped it with alcohol. I always have to wait for at least 3 days for it dry away and become manageable for me to wear again since I don't like the feeling of oil in my ears.
