I have personally found that cleaning canvas and enclosures can take some time. With a flybridge enclosure, the canvas and enclosure might be hard to access. Also, if the flybridge enclosure has twelve individual panels, than you have to take the twelve panels down, clean both sides of the twelve panels and then put everything back together.
I have cleaned a few tenders. Again, I have found that doing a really good job can take some time. I usually first wash the tender with boat soap to remove any loose dirt. I than clean the inflateable tubes with the appropriate inflateable boat cleaner. Next, I might clean the fiberglass hull with some cleaner wax. Finally, I might clean the plexiglass and also wipe down the vinyl cushions with some vinyl cleaner and conditioner.
