So I don't like the scotchgard. My pirata already was a little dirty on the back, so I was pretty mad. Then yesterday I was wandering around the internet and found this. It says specifically that it cleans nylon, and I'm mad enough that I'm willing to spend more money to try it. I bought it today, and it works!!! The fact that it has the brush part is great, too, to get the dirt off. It worked really well on my pirata, and quite well on my foresta. The foresta dirt is REALLY ground in there, so that's pretty good. I definitely think this thing is easily the best out of anything I've used (although I haven't tried the Tide Pen). Thumbs up for the Gel Cleaner!
