Review on 🔧 Squeaky Patented Hinge Lubrication: Say Goodbye to Annoying Squeaks! by Daniel Fung

Accidentally sawn...always a mess when using WD-40 on hinges. I have 4 hinges on all doors, not 3. For $7 I decided to give it a try. It really works...the WD-40 residue drips onto the bottom of the Hinge Hero, not the door. Be careful when you take it off and don't spill what's on the bottom... every 2 loops empty the bottom.
