How to refurbish a old and rusted crowbar.
Got some old rusted (partly) iron tools from a friend or your grandparents? These these are usually of higher quality and strength then the basic tools from a local shop. So don't be to quick to put the tools in the trash bin.
Using a steel brush and a file (the workshop tool to treat wood and metal) you can restore the the tools to former glory.

It is very time intensive to use a hand steel brush, therefore I use a steel brush that can be mounted in an electric drill.
Find yourself a drill with a high rpm, and don't use a cordless drill since you will be switching batteries every 5 minutes.
Be sure to use a proper clamp to securely fixate the rusted tool! You are using a steel brush at high speed and don't want to shoot into your clothing or other surrounding objects because the rusted tool was not secure enough.
If possible, use a drill with a second handle, this helps positioning and reduces the risk of damaging your own hands.

It was a good instructable - but I know that if you just wire brush rust (at least thick rust) all you are doing is knocking off the outer layer and polishing the firmer rust underneath. On the ships (steel) we use pneumatic chipping guns to remove the rust and get down to the bare steel.
This instructable is another really good one for restoring old tools if you haven't seem it yet.

To remove and destroy organic material from metal tools it is best to burn it off. Use a burner and pliers to hold it and cool it down in a bucket of water afterwards.
Dry it to prevent rusting, then just continu with the steel brush.
Noto: Don't heat the metal tools to much because the internal material structure will change and it may become softer of more brittle.
The base of phosphatizant is phosphoric acid (same of Coke!) but I don't know the concentration. It does not hurt the skin, makes a grey coat over the rusted iron. You can see it here or in others mine instructables.
