Slippery ans stretchy

i really liked this mat when i first got it, but after 2 months I'm starting to have some problems. I realy liked the alignment lines, as someone new to yoga they're helpful for getting good positioning. The padding in the mat is nice as well. But after some regular use I'm noticing that my hands are starting to slip and the mat is stretching out while in down dog. I've wiped the mat down with a homemade mat cleaning spray but that didn't help.
