A release wrench for a tie down ratchet strap, having an elongated body with a first wrench end positioned at a first end of the elongated body, and a second wrench end positioned at a second end of the elongated body. Each of the first and second wrench ends are notched such that either end can be inserted into the rotating ratchet of a tie down ratchet strap such that rotation of the release wrench causes the rotating ratchet to move. The first wrench end extends in a direction perpendicular to the elongated body of the release wrench, and the second wrench end extends in a direction parallel to the elongated body of the release wrench. As a result, the wrench can be positioned at four different (i.e.: 90 degrees apart) positions when the release wrench is first turned to cause the rotating tie down ratchet to move. This provides a simple and effective way to “un-stick” a dirty ratchet by prying it loose. Since the release wrench can conveniently be positioned initially in one of four different orientations, the wrench can be operated in conditions where there is little clearance for hands or tools, such as underneath or around vehicle trailers or cargo containers.
