Sanders, flap discs and fiber discs work best on long, flat patches of rust. In contrast, wire wheels are suggested for corners and curved areas. Make sure the grinder is constantly moving so it doesn’t puncture or wear away the tin. Consider using a mouse detail sander for smaller areas. Always begin with the coarsest grain and carefully move to smaller grains as the rust wears away. If there is significant scratching left on the tinware try using a fine grain sandpaper to smooth out any of the remaining marks. [3] X Research source
Be sure to use enough white vinegar to submerge the tinware. If you don’t have enough white vinegar to cover the entirety of the object, you can soak a clean cloth in vinegar and wipe the tin. Scrub the rust off of the tinware using a rough sponge or aluminum foil, The longer you soak your tinware, the easier it will be to scrub the rust off. It’s still effective to submerge the object in vinegar for a few hours, but prepared for putting some extra work to remove the rust.
Apply the lemon juice first so the salt will stick. Make sure to have lemon juice leftover to reapply after you pour the salt. Add the salt. Start with roughly half of a teaspoon of coarse salt (or table salt will do the trick) and apply it to the rust stain. Make sure the salt is sticking and that you used enough to thoroughly coat the rust stain. Reapply the lemon juice. Add the same amount of lemon juice you used initially and pour it onto salt. The lemon’s natural acidity makes it a great candidate for dissolving rust.
If you need to reapply the potato, simply cut off the soapy edge and apply the dish soap to the new edge of the cut potato. A mixture of baking soda and water can be substituted for the dish soap if necessary. If the rust stain is small, you can simply leave the potato over the spot for a few hours.
