I use simple green to clean when I am close to the water, because of being biogradable, not being green just responsible, plus the stuff works well.
Other than that I like to use gel soft scrub.

As far as oil I will say I started with mobil 1 synthetic in my truck switched to Amsoil, and I will never go back to Mobil 1. Total difference in oil pressure response to trottle etc.

I also use amsoil filters they are so much better built than FRAM etc. Plus all made in USA.

I use Mequires cleaner wax on hull of boat I know it isn't for boats, but it shines up really nice and it definately beads up for few weeks.

I find boat waxes are hard to get on and off and they don't protect as well and I have been using mequires on everything. Hell I even used it to wax the walls of my walk-in shower unit and believe it or not I haven't got soap scum build up near as quickly.
