Soft, lint-free cloth
Removing rust from delicate items can be a delicate task since most rust removers and abrasive cleaning tools and agents can damage delicate finishes and surfaces. However, there are some rust removal agents that are very natural, very easy to use and very effective0--and they are likely sitting in your kitchen cabinet or under your sink right now. These agents are safe for any surface and will successfully remove just about any rust flakes or stains.
Run warm water over the item. This will help remove any dirt and grime that could make rust removal more difficult. If there is a lot of buildup, then use the soft baby toothbrush to get dirt out of cracks and crevices.

Make a rust-removal paste. Start out with two tablespoons of baking soda in the bowl. Add a teaspoon of vinegar at a time until you have a thick paste that will spread but not run. Expect some fizzing.
Cover the rusty, delicate item with the rust removal paste. You can leave the paste on the item for up to 15 minutes. As the time passes, you may be able to see the rust "lifting" into the paste as the vinegar works.
Scrub the item with the baby toothbrush. Use gentle pressure and circular motions. The baking soda will help abrade off the rust, but will not damage the surface or finish of the item. If you see any stains remaining, you can repeat the treatment up to four times.
Rinse the item off with warm water. Continue to use the toothbrush to scrub of cleaning residue. The item should be pristine and rust-free by the end of your cleaning process.
Dry the item with the soft, lint-free cloth. Do not allow it to air dry or you risk the formation of flash rust almost immediately.
