That is why I spent many evening with rust remover, scrapers, wire brushes and grinder with a wire wheel under mine last summer. It was tough work but the results were worth the effort. This summer I am going to work on the inside of the frame, cleaning and then coating with some great product that I haven't decided on yet. The inside is hard to clean all the dirt and salt out of so I will probably have to make some special wands and tubes to spray and vacuum everything I can out.
This was after many hours of cleaning.
