You could always try boiling your tap water! I personally use Tap water because our water is pretty safe (as far as I know, anyway)... but I suppose it would depend on where you live! For the cheap solution, I'd say boil your water and when it cools off it should be good to use... Good luck! I'd imagine bottled water would be rather costly!!
Everytime that I look at myself I can't believe how awesome I am.
