Engineered Fluids has entered the shooting market with the introduction of its S.P.O.T. brand of lubricant oil, anti-fog lens cleaner and enzymatic cleaner/degreaser. S.P.O.T. (which stands for sand, polar or tropical environments) is a new line of environmentally-safe, high-performance materials whose development was inspired by the diverse demands of today's U.S. military. These products address hazmat issues while delivering superior performance through making maintenance easier and helping hardware perform flawlessly. The SPOT cleaner, in particular, is a water-based, enzymatic cleaner that is safe to handle while delivering a very high pH surface treatment. All you need to do is spray, and maybe scrub gently with a nylon brush or wipe with a clean cloth to get the job done.
