Used it and reused the solution diluted to soak rusty tools and as a spray on . It is important to monitor the progress of de-oxidation . Re-use of the diluted solution as a spray on is possible for lighty oxidized pieces ( like A- coils or lightly rusted steel grating prior to painting) Lots of different uses. A lot better and safer to use than Muriatic acid for de-oxidation .

Jug of Phosphoric acid is working well

The gallon of phosphoric acid is working as designed for my purpose of cleaning the exterior walls of my log home. I am diluting the phosphoric acid concentration in my chemical sprayer.
