Remove rust in enamel tea pot?

To remove the rust:

Slowly stir a small amount of lemon juice into borax, a traditional natural-source laundry additive, to form a paste-like consistency. Apply the paste to the iron stain and let it set in for a few minutes. Once the paste has dried, rinse it off with water. Repeat until all the rust has been successfully removed. Dry it off with a paper towel or cloth towel. Always wear gloves when cleaning with borax since it can be harmful if it comes into contact with your skin.

A pumice bar is another option. Pumice is a volcanic rock made of a rough textured volcanic glass. It can be used as an abrasive scrubbing and cleaning tool. First wet the pumice bar, and then the sink surface. Scrub the iron off the drain. Repeat until the iron has been removed. Rinse off with water.

Alternatively, mix fresh squeezed lemon juice or bottled lemon juice with salt to make a coarse paste. Apply the paste to the rusted areas of the sink or tub, then let it sit undisturbed for several hours or even overnight if possible. This will allow the mixture to really set in. Scrub the rust away with a microfiber cloth or a toothbrush. Rinse it off with water, and repeat if necessary. This homemade cleaning solution leaves your sink or tub smelling fresh.

You can also use commercial cleaning products for sink rust repair. Always read the label to make sure they are compatible with your sink or tub. Bar Keepers Friend, Limeosol, Zud and Magic Eraser are all easy-to-find cleansers that may help with rust removal. Do not use products containing bleach, however, since this is not helpful for rust removal and may even make the problem worse. You can also moisten the rough side of a sponge to scrub away

To repair an unattractive mark or scrape on the enamel, use a food-safe epoxy. Slowly fill in the area where the porcelain is missing and gently press a piece of wax paper over the chip. Apply pressure to flatten the epoxy and work it into the metal underneath. Allow the epoxy to dry according to the manufacturer's directions or overnight.

They make enamel paint for appliances. See if any of them are food safe.

If it's inside the spout there is nothing to do the repair. All you can do it remove the rust when it forms. On the outside you can remove the rust and use appliance paint. Two part epoxy putty would also work.

use it for a decorating piece instead of a tea pot if you are concerned about the rust

many of the paints for rust are not food safe

It is most likely where the paint is coming off. Scrubbing with a steel wool pad can remove the rust but your best bet is to use it for some other purpose and purchase a new pot for heating up water and tea.

I may have to get a new one. This one is cute and my daughter gave it to me. So...it's kind of special.

For a deep clean: If you're dealing with both mineral deposits and rust stains, combine 2 tablespoons baking soda, 2 tablespoons lemon juice, and water in the kettle. Boil for 30 minutes, making sure that there's always water in the kettle. Let cool, then rinse thoroughly and dry. 4.
