Sorry, but must be said...
Guys, I wouldn't normally comment on something like this, and I don't mean to come across as a tree-hugger, offend anyone or cause a debate, but....
Advocating the disposal or rinsing of Alodine by garden hose, presumably down the driveway or in the yard, is a scary proposition in a public forum such as this. If that is not what you are saying, then please accept my apologies for making incorrect assumptions.
Alodine contains forms of Chromium that are considered extremely hazardous to your health, the water supply and the environment in general. While I understand that we use such small amounts in our construction process, the deliberate and improper disposal of any amount of a known carcinogen into the enviroment is IMHO irresponsible, and most likely illegal.
Here is what the US Navy Safety Center has to say about Alodine 1201...
"This material must never be rinsed from aluminum in a sink such as deep sink or bathroom sink or the waste (flushing) water to be disposed of down sewage or storm drains. Alodine 1201 contains some nasty chemicals called Chromium VI Oxide, Chromic Acid and Potassium Ferricyanide that if released into a water supply will completely contaminate that supply."
Ok, I have said enuf and I am stepping down off my soapbox now. Thanks for listening.
Respectfully,
