    Default Where to buy 2 Part Bleach

    I have found plenty of references to using 2 part bleach but after Googling and looking in the local hardware stores I have not been able to find any .
    Hoping somebody here has bought some recently and can help out.
    Cheers

    A two part bleach is sodium hydroxide and hydrogen peroxide.

    Sodium hydroxide is also known as caustic soda or drain cleaner - about $5 for a half kilo at your local supermarket. The hydrogen peroxide will need to be about 30-35%, and you should be able to find it (expensively - $20 for a litre - it cures cancer, don'tcha' know) at a health food shop, or (cheaper) at a pool and spa shop. I don't think the 3-6% stuff at the local chemist will work.

    Note that good splash/hand/eye protection is needed when working with these chemicals! You will know about it if you get them on anything! (sodium hydroxide will corrode glass).
