Dealing with Ingrained Sand
Right now my canopy has some pretty picturesque patterns of fine sand from a landing out (not salty or anything -- the canopy just fell into a big, very muddy puddle). I tried to kite it out on landing, but only managed to drag it through the puddle, making matters even worse
A pretty big chunk of the canopy has been affected, about 30% of the entire top skin, some bottom skin. Which is less damaging in the long run: shake out and leave the ingrained sand there, scrape it off with a towel and a modicum of pressure, or completely wash the canopy?
