After I Buy WD-40 300045 Specialist Rust Remover Soak, 1 Gallon (Pack of 1)I used this to remove rust from several small tools (drill bits, screwdrivers, wrenches, etc). The tools were severely rusted so I let them soak in the solution for 24-hours. After the soak, all of the rust was gone! Very good, but it leaves a dark coating on the metals. I think this is ok since the tools I soaked are still rust free. I used this on my small tools only. For larger tools, such as hand saws, brush clippers, you will need to use a larger container and will need to use a lot more of the solution. For the larger tools I used naval jelly. The WD40 rust remover works great for hassle free rust remover for my small tools.
