The scissor jack in my car is rusted up solid at the screw parts, not the joints(trunk leak, it's been fixed) how should I free up?

PB Blast and fire? Kroil? Rust freeze of spray? Get a new one?

Go to junkyard, get a new one for $2.

I figured as much, and I'm going to the yard friday.

Junkyard, but for fun, just immerse it in a tub of white vinegar overnight.

Ah hah! I was about to make a thread on what soak solution to remove rust from bolts and brackets.

Is it really just vinegar?

Electrolytic rust removal!

I have used this many times, it works really well, just be sure to get the leads hooked up right..

I "voted up" the white vinegar post above. Just get a gallon (or maybe two) at the grocery store and soak it. On rusty bolts or tools, I've usually had to soak them longer than overnight. I just hit them every day or two with a toothbrush until the rust is mostly gone. Then oil it down good and call it a day.

On the other hand...a well-cared-for one is the safe choice in this circumstance.
