Can I Clean This 5 Cent Coin in 20 Minutes?

This dirty 5 euro cent coin needed a serious cleaning, so I turned it into a 20-minute challenge: can I clean it before the timer runs out? In this video, I try different cleaning products and methods step by step, removing dirt and oxidation from the surface of the coin. Some parts start to shine again, but will 20 minutes be enough to get a satisfying before-and-after result? Watch until the end to see the final transformation! This is just a cleaning experiment, not a professional coin restoration tutorial. Cleaning coins can damage their surface, especially if they are rare or collectible, so always be careful before trying this on valuable coins. What product or method should I try next?
