Agree with Jack.I do the same thing . I remove all my personal items and put down dryer sheets as a rodent deterent . My dealer does all the winterazation and any work I need or want done.
I use moth balls along with dryer sheets around the house,but not on the boat . Scented dryer sheets at the $ store work fine . Damp rid I use during season under the helm in a coffee can ( plastic now )
After the vinyl seats are clean, remember to use 303 protectant. Good on windshield and plastics too.
