When Should you Clean your Multi-Tool Apart from the obvious signs of wear and tear such as visible lint build-up, rust, and gunk. It's important to clean your multi-tool after every use. I use the knife on my tool a lot and I just give the blade a quick wipe with a damp shop towel. I also make sure to dry it with a paper towel whenever it gets wet. In addition to cleaning your multi-tool after each use, it's important to perform regular maintenance and give it a deep cleaning to get into those hard to reach areas. I personally give my Leatherman Surge a deep cleaning once a month. However, depending on how often you use your multi- tool and what you use it for, you may need to perform more regular cleanings. Why Is it Important to Clean and Maintain Your Multi-Tool Keeping your multi-tool clean ensures that you get the best out of it. Your multi-tool consists of several moving parts. When sticky substances, sand, dust particles, and other debris get in between these moving parts it prevents them from moving as freely as they should. Thus preventing the tools from operating at their best. Apart from the fact that you want to keep all the components functioning as they should. You also want to prevent it from getting rusty. But wait, aren't all multi-tools made from stainless steel? Although they are made from stainless steel that doesn't mean that they can't rust. Stainless steel can stand up to rust, as it is corrosion resistant but it is not rust proof. This is because it contains carbon. Carbon is good and bad. Carbon helps to keep your tools sharp but also gives it the potential to rust. So, you see it's not just about keeping your multi-tool looking good. Keeping it clean ensures that it functions the way it should and helps to prevent corrosion and rust.
