For UV protection use Spar varnish not Poly.

Instead of soap, I've found TSP (you can get it in paint stores) with a little dish detergent in the bucket is the absolute best for cleaning off all nature of gunk. Wear rubber gloves, diluted its not wildly caustic but it does a job on bare hands.

I might suggest asking about the finishing part in the finishing forum. There's little enough traffic there that the folks who know about finishing are more likely to see your post.
That said: If the door gets direct sun it's very likely that untinted base tint paint is all that will work. It drys clear and has the most UV protection.
If the door does not get direct sun or rain then a genuine marine varnish would be your best bet (after paint.) Epiphanes is often said to be the best of breed. Like all such, it is painfully expensive.
Thanks, Curt
