Getting boat up off the bunks for EZ ON EZ OFF

[sunvalleylaw]

EDIT:  Looked for a thread but did not find one specifically on this.  (the lifting part).  End EDIT.  My new (to me) boat has some discoloration, reddish brown, only in the very rear and the area where it sits on the bunks, from prior moorage by prior owner.  Would like to get that off, and put some polish and poly on to re-seal it. Seems like EZ ON EZ OFF or toilet bowl cleaner or Miuratic acid is the way to go, but I don't really want to climb under and work with that stuff while, and there are stains that would be covered by the bunks anyway.  So I want to get it up off the bunks so I can use a sprayer, and a brush on a stick, then put some sealant or good boat polish on after dry.   I have done a search, and cannot find any threads on how to safely do this.  Suggestions?  Or, I could pay some guys in Boise to do it, but that sounds expensive.

I would short load it onto the trailer and do the work on the boat ramp, then go back and finish the trailer loading when you're done.  I used "The Works" toilet bowl cleaner, worked like a charm.  Just grab a disposable mop and you'll be nowhere near it.
