For many years, I worked in a very noisy factory(120db) and we had to wear ear plugs. I had a lot of wax that got shoved back into my ear and an ear doctor told me to use baby oil every few days. The baby oil makes the wax soft and soluble. I am still doing that 35 years later. Every couple days, I use a q-tip with baby oil before showering.
My only concern is what the oil might do to the Agil Pro ear piece. Recently the chimes became faint in one and they replaced it. I don’t know if the oil played any part in that or not.
