Should I use sandpaper to clean the rust off old tools? Can I soak them in vinegar or lemon juice?
Would I be better off just buying new tools?

Norm's answer: Given enough time, rust will damage metal permanently. Here are some ways to keep it from forming on your tools and to get rid of it if you've got it.
To keep rust at bay: Because dust attracts moisture, store tools in a dry place, such as in a drawer or a toolbox. For extra protection, add a canister of silica gel or strips of vapor corrosion inhibitor, like the ones made by Bull Frog. They emit a gas that deposits a protective layer on metal surfaces. In damp basement workshops, keep a dehumidifier running.
When rust gets a foothold: Spray lightly rusted surfaces with a penetrating lubricant like WD-40, then scrub with a heavy-duty Scotch-Brite pad. Stay away from sandpaper; it scratches metal. Wipe off excess lubricant before putting the tool away.
For more heavily rusted metal, try a spray-on, wipe-off, acid-based rust remover like Rust Free. Follow with a rust-inhibitor spray like Boeshield T-9, which leaves a thin, waxy film on the surface. Wipe away any excess immediately.
Storage:If you're lucky enough to own any of the old wooden boxes that tools used to be packaged in, they make great storage places. The wood helps absorb moisture and shields the tools from humidity.
