Did you know you can loosen a rusty screw using only vinegar? That’s right, the regular old white distilled vinegar you have in your pantry does an excellent job of dissolving rust.
Perhaps the best part about this handy little trick is that the vinegar won’t harm or scratch the surface you’re working on, therefore making vinegar an excellent choice when working on antiques or other items you want to preserve.
How to Loosen a Rusty Screw Using Only Vinegar
For this to work, simply pour or dab some white distilled vinegar on the rusty screw. Allow it to sit as long as possible (a few days if needed) so that the vinegar can get to work breaking down the rust.
After the rust has dissolved a bit you can try breaking the screw free again with a screwdriver.
Now, if you want to re-use the screw (perhaps in the restoration of a vintage piece of furniture) you can continue to soak the screw in a jar of vinegar for a few days. This will continue to strip the rust off the screw making it easy to re-use once you’re ready to reassemble.
By the way, this process works on rusty nuts and bolts as well.
Now go ahead and give it a try for yourself!
