These weak acids are less caustic and are safer to work with and they are easy to dispose of. 3 Water-based solutions: Acid-free, water-based solutions use a different chemical process to react specifically with rust and remove it, leaving the underlying metal unaffected. They are the safest option to work with. 4 Electrolysis: Electrolysis speeds up chemical reactions and destroys rust by applying electrical current to the reaction. This can also be dangerous and can produce toxic chemicals and fumes. 5 Mechanical: Metal parts can be scrubbed and sand blasted to mechanically remove rust.
