Lyra Delos Stylus Crud on top of cantilever

Looking for suggestions as to how to get stylus crud off the top of my Delos cantilever. No idea why it would be building up there. I’m sure it’s because I live near water so there’s a lot of moisture in the air so everything is tacky in this house. I’ve tried a medic eraser and an audio Technica ultrasonic stylus cleaner and it’s lessened but still there. Here’s a link to the best picture I could take. Stylus is nice and clean but I can't imagine this is helping the sound.
