I bought new Leatherman Wingman... And I performed my "Deep Cleanig" process. First I submerge Tool in hot water (not boiling, just hot) with some dish wash added. I let it soak submerged for about an hour, during that time I'm opening and closing the tool for several times and I'm running it through the water a little, to get as clean as I can. After that I wash the tool from dish soap running it thru the water from the tap, I immediately dry the tool, and then I spray it With Brunox Turbo Spray and leave it to soak for about an hour, and then I remove the turbo spray with the rag and put on Brunox Lub & Core, let it soak for an hour and clean it with the rag... Through all the process if there is need I use the brush for cleaning parts witch are dirty or rusted. I have done this for all my Leathermans (I got about twenty of them) and there was no problem. But, when I put the Wingman through this process... after an hour in water... the pliers head gone rusted! Everything else was fine, only the pliers head gone rusted...! I was very surprised (not in a good way...) I cleaned the rust write away after soaking it a little in Brunox Turbo Spray but it left some dents and black worm like holes and spots in the tool, I needed to use some fine emery paper to remove that, and the pliers head will never look the same... Funny thing is that at the same time I was doing this cleaning process to the Wingman I was doing it to the Sidekick also at the same time, and there were no problems or any rust on sidekick... Did anyone had the same problem or any experience with this...? Does this mean that the plier head on Wingman was from bad series...? Does this process of cleaning that I'm doing can affect overall quality and consistency of stainless steal, or this is just the surface problem... Thank You!
