Pliers and other tools made out of iron or steel need some regular maintenance to avoid getting rusty. For this task we need some lubrification fluid, preferably with an anti-rust component, a green scouring pad and some paper kitchen towels.
I start by spraying a bit of the lubricant on a paper towel and rubbing it over the tools to clean them. then I check for rust. I scrub the scouring pad over the rusty tool until it’s clean and rub on a second layer of lubricant.
For tools that I don’t use as often, such as the dapping block and punches, I generally spray a coat of lubricant over the whole thing and then cover it with a cloth or plastic to protect it from humidity and dust.
For larger tools with moving parts, such as the rolling mill, I use white grease for the gears and spray lubricant for the rollers, also using a paper towel.
