What You'll Learn

Use vinegar, salt, and warm water to remove rust
Vinegar, salt, and warm water can be used together to remove rust from a Coleman stove fuel tank. This method is natural and effective, although it may take longer than commercial rust removers.
First, create a mixture of vinegar and salt. For a full gallon of vinegar, add a full cup of salt and mix until the salt is dissolved. You can also use a half-gallon of vinegar with a half cup of salt. The vinegar contains acetic acid, a weak acid that breaks down rust particles.
Next, submerge the rusty fuel tank in the mixture. Leave it to soak for at least 12 hours, or up to three days if the rust is particularly stubborn. The longer you leave it, the more effective it will be.
After soaking, scrub the fuel tank with a 3M-style pad or a soft-bristled brush, such as an old toothbrush for detailed areas. You can use a brass-bristled brush for any remaining tough rust.
Now, neutralise the acid by filling a bucket or tub with water and submerging the fuel tank. Then, pour out the water and add a mixture of half a gallon of water and half a cup of baking soda. Let the fuel tank sit for about 10 minutes.
Finally, rinse the fuel tank under warm water and dry it thoroughly with a soft, microfiber cloth. You can also use a towel. Polishing with fine steel wool can add a nice sheen to the metal.
This method can be used for other rusty metal items, but be aware that vinegar and salt can eat away at aluminium, so avoid this method for aluminium items.

Apply naval jelly to rusty areas
To remove rust from a Coleman stove fuel tank, you can use naval jelly, a mixture of phosphoric and sulfuric acid. This method is faster than using vinegar and is effective on rusty metal and dirty brass.
To apply naval jelly to rusty areas, start by disassembling the stove to access the rusty parts. Using a toothbrush, spread the naval jelly generously over the rusty sections of the fuel tank. Ensure you cover all the rusty areas, as the jelly will stick to vertical surfaces, making it ideal for stove struts.
Let the naval jelly sit for 15 to 30 minutes. During this time, the phosphoric and sulfuric acid in the jelly will react with the rust, converting it into a removable complex salt. After the waiting period, rinse the treated areas with warm water to remove the dissolved rust and residual jelly.
Next, use a brass brush or a very stiff brush to scrub the areas where you applied the naval jelly. This will help remove any remaining rust or jelly residue, ensuring a thorough cleaning. Finally, apply a light coat of oil, Vaseline, or WD-40, and use 0000 steel wool to shine and protect the cleaned surfaces.

Hand-wash the stove's components separately
To hand-wash the stove components separately, begin by taking off the fuel tank, which includes the generator and tip. Then, proceed to carefully disassemble the stove, separating the burners, cooktop, and case. Avoid the temptation to scrub the burners vigorously, as disturbing the rings can lead to lighting issues with your stove. Instead, opt for a gentle hand-wash using warm, soapy water for these components. Ensure that you dry each part thoroughly by placing them upside down before reassembling the stove.
For a deeper clean, especially if there is significant rust or grime buildup, consider using a solution of vinegar (acetic acid) and salt. Combine one cup of vinegar with one tablespoon of salt, heating the mixture until it is near-boiling. Completely submerge the stove components in this solution and let them soak for at least an hour. Afterward, rinse them in warm water and scrub with a brass or stiff brush. Repeat this process if necessary until the desired level of cleanliness is achieved.
Another effective method for removing rust is to use naval jelly, which contains phosphoric and sulfuric acid. Spread the naval jelly onto the rusty areas with a toothbrush. This method is particularly useful for vertical surfaces, as the jelly will stick in place. Leave the naval jelly on for 15 to 30 minutes, then rinse it off with warm water. Follow up by brushing the parts with a brass or stiff brush and applying a light coat of oil, Vaseline, or WD-40, along with 0000 steel wool to restore shine.
It is important to note that some cleaning methods can be time-consuming and labour-intensive, especially if dealing with heavy rust or stubborn stains. Always exercise caution when handling cleaning solutions and acids, and ensure proper ventilation during the cleaning process. Additionally, always dry the stove components thoroughly before reassembling to prevent water from being left inside the stove, as this can lead to rusting and potential functionality issues.

Dry the stove parts upside down
Drying the stove parts upside down is an important step in the process of removing rust from a Coleman stove fuel tank. After cleaning the stove, it is crucial to ensure that all components are thoroughly dried before reassembling the stove. Leaving water inside a camping stove can lead to rust, which can affect the stove's performance and cause further damage.
To dry the stove parts upside down, start by disassembling the stove if you haven't already. Hand-wash the burners, cooktop, and case with warm, soapy water, being careful not to scrub the burners too aggressively, as this can affect the stove's performance. Rinse the parts with warm water to remove any cleaning solution residue.
Next, place the stove parts upside down on a clean, dry surface. This position allows gravity to help with the drying process, ensuring that any remaining water drips out of the components. It is essential to let the parts air-dry completely before reassembling the stove.
Depending on the environmental conditions, the drying process may take several hours or even a full day. Ensure that the area where the parts are drying is well-ventilated to expedite the drying process. Avoid using towels or cloths to dry the stove parts, as this can leave behind fibres or lint, which could affect the stove's performance.
Once the stove parts are completely dry, you can proceed to the next step of the rust removal process, such as applying a light coat of oil or reassembling the stove, ensuring that all components are properly aligned and secured. Remember, a dry stove is a good stove, and taking the time to dry the parts thoroughly will help maintain the functionality and longevity of your Coleman stove.

Finish cleaning with oil, Vaseline, or WD-40
Once you are done cleaning the rust off your Coleman stove fuel tank, you can finish the process by applying a light coat of oil, Vaseline, or WD-40. These substances will help to protect the metal from future rusting and keep your stove in good condition.
If you choose to use oil, opt for a light variety and apply it with a cloth or brush, ensuring you cover all the metal surfaces. You can also use steel wool to apply the oil, which will help you reach any nooks and crannies and give the stove a nice shine.
Vaseline is another effective option for protecting your stove from rust. Apply a thin layer of Vaseline to all the metal surfaces, using a cloth, brush, or your fingers. This will create a barrier that prevents moisture and air from reaching the metal, thus inhibiting rust formation.
WD-40 is a well-known and effective water displacer, which means it will drive out any moisture from the metal surfaces of your stove and leave a protective coating to prevent future rust. Spray a light coating of WD-40 over all the metal parts, ensuring even coverage.
No matter which method you choose, be sure to apply the protective coating soon after cleaning, as the rusting process will start immediately.
