My Molasses rust experiment results.

Thanks for sharing guys. So my daughter brings the grandkids over yesterday ( just like every weekend ). You should have seen the look on her face when I said I want a 5 gallon bucket of molasses for Fathers Day.
Now a note about chlorine and rust. The Fadal cnc mill at a small shop would sometimes stand for a week. During that time the 30 gallon sump of water based coolant would get funky. The operator ( Tim ) brought a gallon of Clorox to work after Christmas break and poured into the mix to kill the odor. The parts he started on were tool steel. Faster that he could load the next part and turn around, the part removed developed light surface rust.
I mention this because public tap water contains as much or more Chlorine.
I'm thinking I'll need a 2nd 55 gal. barrel of distilled water for rinse cycle.
That or power up my old well pump and use that water for rinse.
Happy moparing

Good info.. i am on a well system ( no city water which is fine by me.)
after i removed the parts and washed them down they did start to discolor with light surface rust. i just primed up parts after they dryed.
