I wipe mine down after every trip out. I keep some towels in the trick and so it before i leave for the day. When i wipe it down i spray it with some spray detailer, it really helps take the scumline off. I try to wax mine monthly, i was using a marine wax and it worked good but last time i ran out of wax and used some good old mothers california gold hard paste wax on it. i like the mothers much better then the other stuff i was useing, it seems to last longer and the color on the boat looks much deeper and nicer. Next time i wax it i plan to use the mothers again. I also vac mine out every couple of trips to keep the pebbles down. Lasy year i steamcleaned my carpet and i was amazed how much dirt came up. i plan to do it again this year.
