Why not let a rust dissolver reform the surface only in the areas that need attention. Instead of using sandpaper that might alter the tool coveted geometry, round over corners or create unintended angulations I prefer the chemical approach. But anytime that rust attacks a flat surface that was accurately machined by the factory or perhaps sanded true and flat by the user later (think about a plane that you trued up) my approach is much more measured. If a tool handle had rust on it, or if rust terrorized the curved blade of an axe, I would have not hesitated to use sandpaper to emancipate the tool from the rust. This summer I decided to rehabilitate these tools. Even though the square was kept in a non humid room, the mere fact that its cast iron sole was in partial contact with the ledge was enough to encourage malevolent condensation to evolve and act upon the poor square. I once let the mine seat on the top rail of our window’s pane only to discover later that the underside of the square’s head was covered with a plum of rust. Remember not to neglect your precious 12" Starrett combination square too. Waxing or oiling the sides and soles of planes, as well as the blades of our gouges and chisels is a good preemptive strategy. Certainly, there are actions we can, and in fact should take to protect our tools from humidity. By the way, this can happen on the soles of planes too, so unless you suspend them on a ledge or cleat to allow air flow all around, they also will rust in humid conditions. But as temperatures dropped, captive humid air condensed, and tiny water droplets accumulated on the underside of the blades and began to turn the iron in the steel into iron-oxide, or rust. During the day, humidity surrounded the tools but probably did not penetrate the thin protective coating. The owner probably held them in a drawer or on a shelf in a humid environment. That was certainly the result of repeated intervals of condensation that plagued the underside of the blade. One face of each of their steel blades (or arms) was rusted while the opposite face still retained most of its gun blue-ish coating. The tools never seen any use but they have had some intimate interaction with corrosion. Shrouded by the cloak of humidity it begins to tarnish and eat away your precious tools.Ī few years ago I bought on ebay three British made layout tools: two squares and a sliding bevel. The grand wrapper of all ferrous metals (accept stainless steel) steps in. We all have been there, or so I assume: owning a tool, investing time and effort in forming its sharp and shiny edge, assuming that it is safe to leave it for a week or a month on that shed, garage or basement shelf, or tucking it into a drawer for the summer, and then - calamity strikes.
NAVAL JELLY RUST REMOVER PLUS
It robs us of time and resources, plus it corrodes and takes its toll on our psychological well being. And no, I am not talking about battlefield blood shedding and carnage, I am talking about a more existential campaign that is waged on a daily basis against iron’s mortal enemy - rust. Since the dawn of the Iron Age humans had been engaged in a fierce battle.
