WE have a 20 year old Coleman Fleetwood Lakeside, recently purchased from an amateur camper, and the canvas has been neglected for quite some time. I have read numerous suggestions for cleaning/stain removal, but would appreciate a general consensus for the best product, that requires minimal effort, for stain removal and general cleaning. Also, the awning, which is vinyl, could use some TLC, so, suggestions for that as well would be appreciated.
