Cleaning gravel soup out of canopy
I suspect I am not the only one whose canopy looks like this (see attached photos). The unfortunate result of the rain and the fresh dense grade in the landing area at Bridge Day was a concrete like soup mix that hasn't easily washed out of my canopy. I tried suspending the canopy and gently washing it with a hose. The water running off was gray, so I know I did some good, but when it dried, it is still filthy. Thoughts? Jump it till it blows clean? Immerse it in the bathtub? Try washing it with the hose a second time? Quit whining?
I have consulted the owners manual ("Don't get your canopy wet" and "Spot clean small stains with soap and water" don't really seem to apply) and I have sent CR an email requesting their advice, but thought I'd post this here as I suspect there are some others out there looking at the same issue.
