What's the best way to get this surface rust off?

UPDATE:
Thanks everyone for the advice on the phosphoric acid.

Here is a before picture of some of the newly rusted tools:

The pink slime was muuuuch more gloppy than I had expected:

Did you use two thin to medium coats within 20 minutes? (instructions)
Brushed on. Allowed to cure 24 hours?

The metal turned black and was washed off in a bucket:

Washed using rubbing alcohol or mineral spirits?

Then it was dried before applying motor oil to the metal:

I'd likely would have done two treatments before oiling. (two thin
coats each treatment)

In hindsight, the rust-spotted chrome worked the best, and
the prybar steel worked worst - with the saw blades fairing
rather poorly with respect to restoring the original surface:

Within minutes of drying, a white "lard" formed on the tools:

Nobody had mentioned that white lard. Any idea what it is?

Not sure unless the tools were not coated uniformly (close), allowed
to cure completely.
