Bests & Worsts Reviews from Amazon

It's beautiful, comfortable, and I haven't had problems slipping on it. But it stained the very first time I used it, got worse the second time, and the stains haven't budged. I've followed Gaiam's cleaning recommendations and bought the best-reviewed yoga mat cleaner I could find, but nothing. The stains are ordinary. They're sweat from my feet moving up and down the mat. The third time I used it, I found myself significantly altering the way I moved through class, so I wouldn't worsen the stains. A distracting hurdle for someone new to yoga. Picture attached (after cleaning attempts). I have enough issues feeling self-conscious at yoga without being the guy with giant skid marks on his mat. I bought this mat to help my confidence and commit myself to yoga, but I've been skipping more classes than ever. I admit that's pathetic, and those issues are mine, not Gaiam's, but a mat this expensive shouldn't irreversibly stain the first time you use it because you got sweaty. I thought I was buying something long-term, but now I feel like I bought something disposable. Yes, the mat still functions, but if you'd scoff at the thought of buying a new mat with stains on it, why should you be okay with one that stains after one use?
