naval jelly. There ain't no so so when ya wanna strip the bluing. ya either do it or mess around with it for weeks trying to figure out what went wrong. Get some rubber or surgical gloves, a clean Cotton cloth and swab it on. Be prepared to wash it off in a tub or laundry sink according to instruction's on the bottle.
Repeated rinsing and washing with dish soap after application works well to stop the action. Use luke warm water, and it can be done over and over again until the desired results are found. This is a 1/2 hour job. A fine steel wool can be used towards the end of the process. but the wool will degrade rapidly with the naval jelly chemical and a need to rinse/wash the iron oxide will increase.
this i know from experience,
