I have seen earth bath at petco before but I haven't used it. I like espree products better and they're natural, too. Jenny (mimimomo) is a member here and I have ordered a lot of my babies grooming supplies from her website 
toplinepet.com . For grooming I definitely recommend getting your baby a madan brush and comb.. I can't groom Chloe without these 2! Also, for the face.. I just received Espree Plum Perfect face cleanser yesterday from Jenny and I used it on my baby.. it smells really good! It's natural and tear-free. I'd recommend that instead of wipes.. or you can also use a little bit of tea on a cotton pad, my vet told me that works, too.. but I like the espree face wash better. Jenny has good brands of shampoo and conditioner on her website.. I'm using the show style silky show shampoo and conditioner right now which I also got from Jenny, but I use that on the body only because it isn't tear free. They do have tear-free versions of it too, though.
