I’m referring to Echo Red Armor Cleaner.
Apply it to the blade of various tools like scissors, clippers, pruners, hedge clippers and to bolts like the lawn mower blade bolt. It's just a light oil that can clean and lubricate like it says. If you're not using something for a while, you can apply to prevent rust from forming. I used it today when changing my mower blade out to lubricate the bolt. It had a minor dirty coating of something that is five years old. This went on smoothly, and my bolt was easy to tighten.
