I agree with Mikala. Hydrogen peroxide is available in most drug stores or department stores but I have yet to find it in the large bottles. It only comes in the small, first aid size here in Dumaguete.
Agree Hydrogen Peroxide is available at any pharmacy. I have never seen Washing soda here yet but it is easy enough to make from plain old baking soda. See: http://naturesnurtureblog.com/ttt-turn-baking-soda-into-washing-soda/
