Oh, poor Josie Labs are especially prone to ear infections. I wash out Star's ears weekly with OtoClens too. The vet reassured me that the atanomical structure of the Lab's ears allows you to clean out their ears deeply, with Qtips or gauze and the cleanser, without damaging the ear drums. When she does develop an ear infection, she usually get's treated with Otomax, a liqud dispensed into the ears with a long applicator. And yes, it is "greasy." Hugs to Josie!!!)
