Many private and commercial aircraft owners and operators have cleaned their craft with Simple Green or Crystal Simple Green for many years. However, these products do not have Mil-Prf (military testing) authority. The testing involves very long (168 hours in one test) soaking of various metals in the solution and then a corrosion inspection. If an aircraft owner only wants to use mil-prf approved products; he will not want to use Simple Green. Please see the additional information under "Aluminum".
