How To Clean A Military Aluminum Kettle?

1. Potatoes. A military aluminum kettle will be covered with scale after being used for a long time. You can try to put a few potatoes in the kettle and cook them for a few hours. The thick scale will fall off by itself without damaging the kettle.
2. Baking soda water. You can pour about 500 grams of 1% baking soda water, or heat the caustic soda water into the kettle, shake it gently, and the scale can be removed.
3. Vinegar. If the military aluminum kettle is rusted, pour some vinegar in the kettle and gently scrub it with a soft brush. Make sure the vinegar is fully in contact with the rust. If there is still stubborn rust, you can pour some hot water and continue to scrub it. After the rust disappears completely, rinse it with clean water.
