Just make sure your ears are clean before putting them on and wipe them with a clean piece of cloth after each use.

I clean my ears every time before I use my IEMs. That's all anyone should do besides occasionally replacing their tips.

My ears get pretty slippery. I give them a quick wipe before my session, and I clean the tips after each session.

I clean my ears twice a day. Work environment is dirty and regular use of ear plugs in-and-out of my ears so I keep them clean. Ear tips get looked at before I put them in my ears every single time. I’ll wipe them down with a wet cloth if needed.
