Squeaky hinges and door latches that don’t close smoothly really bug me. Applying WD-40 to resolve these problems is really satisfying. Here are before and after clips at the place I’m staying in Berlin.

Take pride in the doors in your home or office. Apply WD-40 to hinges and latches and anything else that squeaks. You’ll feel great. You deserve it.

My inspiration for the video came from KnobFeel, the blog with clips of one person turning knobs to evaluate their feel.
