Okay so this happened to my friend who has an older Swimtail that she bought from another friend ( who got it in 2017ish I think)? So we went to the lake that is a bit muddy and her tail which is a blue mako tail got really stained from all the mud and it took her a lot of scrubbing apparently to get these mud stains out. Now I have gone to the same lake in my Mertailor Moonkelp in the regular fantasea fabric, and a pink Suntail and I have not had this problem. Has anybody else had issues getting muddy stains out of their Swimtail like this? Or could have possibly because it's a scuba knit fabric? If that's the case that makes me terrified to take my Mertailor Whimsy tails to the lake.
