Oil slick looking surface inside skimmer

It's probably just sunscreen or suntan lotion. You can get a special sponge or a "scumbug" if you want to absorb and dispose of it.

I found if you just use some papertowel and dip it into the offending oil slick and pull it out it gets 90% of it. Beats buying those $10 sponges. I guess it works best if its localized to the skimmer.
