Personally, I don't clean my Remora more than once every 4 months. You're supposed to let it develop a "film" on the inside that somehow helps with skimming. Aqua C recommends not to clean it very often as well. Just clean out the collection cup, including the tube that the bubbles come up, once every 1-3 days.
I emailed Aqua C about the wet skimmate, they said to expect it. Lots of skimmers will give you a very dry to concentrated skimmate, with this one its different. Expect wet skimmate.
stuccodude- I don't think you have the right skimmer. The only adjustments on these skimmers is the collection cup height, which adjusts the concentration of the skimmate ultimately. The lower the collection cup is, the clearer the skimmate, but the more skimmate it may pull out. Personally, mine is somewhere in the middle, and I get really dark skimmate that has the consistency of water.
Remember to keep your hands out of your tank as much as possible. Not only does it stress your inhabitants, but it also will render the skimmer less effective. The oils from your hands inhibits bubbles from forming on the surface and traveling up the riser tube and into the collection cup, thus equaling less skimmer performance.
