i use an old soft bath towel and spray a little Quik Detaler and wipe it down, looks just waxed and it keeps it from getting all stained and slimmed up next time out. i think Maguierrs or Dupont makes it.
50/50 water and vinegar, especially on the motor. Quick wipe down with BBS after every use. Spray BBS into a damp towel and follow-up with a quick buff with a dry towl. Take care of youyr electronics screens after every use. Besides scratches, it'll keep the boat in like new condition for years.
