This is a recipe for DIY Household cleaners that are environmental friendly and I would like to try it out.

However, I would like to know where can I find Borax and Hydrogen Peroxide.

Hydrogen peroxide is sold in pharmacies.
If I'm not mistaken, borax is "pang sar" in cantonese??? IF SO, then it can be purchased from chinese medical shops.
