For the last 36 years of turning wrenches, we have tried numerous products on the market to remove rusty retainers. None have been as successful as the WD-40® Specialist® Rust Release Penetrant Spray. It was amazing how the rust released and retainers were removed without delay. There is no doubt in our minds that we have found the perfect solution to rusty retainer problems.
