What Went Wrong - Citric vs Phosphoric Acid on 30 years of rust… (Real Test Results)

What Went Wrong - Citric vs Phosphoric Acid on 30 years of rust… (Real Test Results). What is the best way to remove rust? In this video, I test two popular methods, citric acid and phosphoric acid on real 30+ year-old rusted metal. No theory, no guessing. Just real results. I used old floor pans and deck lids to see what actually works in real conditions. If you deal with rust on cars, tools, or metal parts, this test will help you choose the right method and avoid wasting time or money on the wrong solution. I didn’t keep things perfect on purpose. Some metal pieces were sanded, while others were left untouched. Some were fully soaked in acid, while others were exposed to air. This is important because not everyone prepares metal the same way. You will see how each method performs in different situations. This gives you a more realistic idea of what will happen in your own garage or workshop. I tracked everything step by step from 1 hour to 22 hours. You will clearly see which acid works faster and how the results change over time. Citric acid works by removing rust, while phosphoric acid converts rust into a protective layer. Watching the changes over time will help you understand which method is better for your specific project. This video also shows how important surface prep and soaking are. You will notice a big difference between submerged parts and parts left in open air. If you are restoring a classic car, fixing floor pans, or cleaning old metal, these small details can make a huge difference. This test helps you learn what actually works best in real life. At the end, I break down the pros and cons of both methods so you can decide which one is right for you. There is no bias just real results. Always remember to use safety gear like gloves, eye protection, and proper ventilation when working with acids.
