When a look into your toolbox reveals old, rusty bolts, you may be tempted to just throw them out and buy new ones. However, if the bolts are particularly old or designed for a speciality product, you may not be able to find new ones in the right size or shape. You also may have rusted bolts already in place that are challenging to remove. You may be able to use your rusty bolts (or remove them more easily) if you clean them.
Fill a bucket with vinegar, diet cola or a rust remover solution you get from your hardware store.
Place the rusted bolts in the bucket, fully submerged, and cover the bucket.
Leave for 24 hours, then rinse clean.
Fill a spray bottle with vinegar, diet cola or a rust remover solution you get from your hardware store.
Spray the area with the rusted bolts thoroughly and let sit overnight.
Scrub the area with an old toothbrush, a wire brush or fine-grade sandpaper.
For extra stubborn rusted areas, apply heat with a propane torch for a few minutes until the metal begins to expand, then scrape the rust away with a wire brush.
