CLP - Cleaner Lubricant Preservative. Shake well before use. It is a superior cleaner, as the "well shaken" fluid has an affinity for metal, and loosens anything in its way to get to the metal....but give it time to do its job. It's a good lubricant, and an "adequate" preservative. There are better preservatives out there...but two outta three ain't bad (MeatLoaf). It's great for metal, but I, too, am careful with it on wood.
