You can also try oxalic acid. It is a white crystalline powder which will dissolve in water or dilute hydrochloric acid, which seems to speed things up. Hydrochloric acid is corrosive and oxalic toxic. LD50 for oxalic acid would appear to be about 25g, so accidentally swallowing a whole ounce of the stuff would be unfortunate to say the least. You may have to sign the poisons register at the pharmacy. John Schmitt -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/ |

DIY'd from rhubarb, then bought as pure Oxalic acid. The rhubarb juice produced a more pleasing 'whiten', (less harsh), and was far easier to wash off. -- Tony Williams. |
