Awning cleaner

How about Nikwax Tent and Tear Solarwash

I have a Kampa air awning. After 4 years of use it was looking a bit dull/dirty. After one eventful trip when an extreme storm pulled a majority of the ground pegs out and it out of the awning rail. I had to wrestle to get it deflated, the rest of the pegging out and bundled away until the weather had calmed. The awning was now covered in mud and some blood that I had shed during the battle. I tried a few different cleaners but couldn’t really get the dried blood out. In the end I just inflated it in the garden and used traffic film remover ( gunk) and the jet washer on a soft setting- keeping the distance a little further away. No damage was done and the awning looked as clean as it did when I first purchased it. It’s still in use two years later and doesn’t leak!
