Disposing of acidic solution
Any suggestions to properly dispose of this acidic solution after passivation. Is it safe to simply dilute with water and flush away? Citric acid does not sound too bad but if I am wrong please let me know. Wife would kill me if I melted her crapper or burnt her butt...:p
I went with the sand paper approach for this build. I will look for a powder coater for a future build.
Passivation Final Test/Verification
Well I completed the passivation process last night. So on with the build. I did not have the luxury of heating the solution so they simply soaked for two hours at room temp in solution. I followed all of the instructions so I presume all is good. From what I have read there is no real test to confirm the process was successful other than time will tell. If you know of any test, please let me know... Thanks a ton for all of your help and advice!
