I'm not going to go into a hugely detailed review about this product, but all I do have to say it WOW. 

I read about it on another forum on a way to spot clean your suit and was really good for white parts. My Jacek fursuit head got a few dark spots this past picnic so I thought I would give it a try. I didn't think it would work as well as others told me it would, honestly, but I tried it out (on my feetpaws first) and was just amazed at how white it got them again! So after seeing that it was just fine reacting to the fur I use, I cleaned my fursuit head. It got the fur looking like new again! The white is bright, along with all the other colors. And all the dirt stains came out.

So I thought I would just right this little review in case your suit has some spots and you're feeling a bit discouraged after trying to get it out with water and soap and a whole lot of elbow grease with no luck, just try using some Folex. I bought mine at Home Depot in the cleaning supplies section. It was $7.00 for the "Giant Size" and is labeled as a "Instant Carpet Spot Remover"

Hope this was maybe a little helpful to someone out there!
