Another effective method is to mix some baking soda with water and scrub the rust off. You may have to repeat this process several times to completely remove the rust. Once the rust has been removed, you can paint the insert with heat resistant paint. 

If you don’t want to use a rust dissolver, you can also scrub the rust off using white vinegar. Vinegar is an acidic substance, so it will dissolve the rust easily. However, it can damage the metal, so you should not leave it on the surface for a long time. 

Another option is to pour lemon juice onto the rust. Lemon contains citric acid, which will help to dissolve the rust. After letting the mixture sit for a few minutes, rinse off the rust with water. 

Aside from using lemon, you can use salt and lime to remove the rust. Mix the ingredients together and allow them to set for two to three hours. Then, rinse off the solution thoroughly. 

If you’re looking to get rid of rust in your fire pit, you can apply a layer of black grate polish. Just follow the instructions on the label. Keep the paint at least two feet from the fire pit. Make sure that you apply the paint evenly and in smooth, circular motions. Do not be tempted to apply too thick a sealant. It can cause cracks and bubbling. 

In addition, you can use a stripping knife to remove any paint residue. Be careful when doing this, as the chemicals involved can be harmful. Additionally, you should wear protective clothing when you use any of the above methods. 

While you’re at it, you might as well give your cast iron fireplace a new coat of paint. Metal paints with oil bases work best for preventing rust. Using a rust-proof metal paint will prevent the rust from ever occurring again. 

If you have a rusted fireplace insert, you can try scrubbing the rust off using a soft brush, sandpaper, or elbow grease. You can also use a rust remover, but these products have toxic chemicals that can hurt people. To avoid any risk of injury, you should always use these products in a safe, well-ventilated area and wash off after the recommended time. 

Whether you are restoring an antique cast iron fireplace or a modern gas or electric unit, it’s important to clean the metal. Leaving rust behind can be a big safety hazard and can reduce the structural integrity of the fire pit. Luckily, there are a variety of rust removers available that are safe to use and can get rid of rust quickly.
