cleaner for bird poop

[HerbertFriedman]

Some vengeful winged creature made a mess on my navy blue (Sunbrella) dodger. I tried 303 multisurface cleaner, brushing followed by a strong hose blast, not very good results. Any suggestions for something better?

I use the “Amazing Roll Off All Purpose Cleaner”. The word “Amazing” is not my adjective but part of the name although it is amazing for just about everything topside including bird poo on canvas. Wet it down, just a little, spray on Roll Off, wait a minute or two, scrub and then rinse.
