Your lab had the best value and the product lives up to expectations.
I used the recommendation from Home Depot to use Oxaclic acid to remove rust from tools. Mix three tablespoons of power into 1 gal of water. It said to soak for 20 mins, but to get any reaction I had to soak two hours or more, I then rinsed, followed by scrubing tools with water and Brillo pads. This seemed to work well together.
