How to Clean a Coin Correctly
TLDRThe speaker shares their method for cleaning various coins, emphasizing the importance of testing the cleaning solution on the rim of copper coins first due to their reactive nature. They demonstrate the process using a hydrocarbon distillate, highlighting its effectiveness on metals without altering the coin's patina. The speaker also introduces a new product, BU Plus, which is being trialed for its ability to remove residues without harming the coin's surface, offering a potential solution for coins that have residues that return after cleaning.
Takeaways
- 🧼 The speaker uses a q-tip technique to clean coins by pinching and pulling it to make it soft before swiping on the coin's corner.
- 🌈 The cleaning solution is effective on all metals but requires caution with copper and bronze due to their reactive nature.
- 💡 When cleaning copper, it's advised to test on the rim first to prevent altering the coin's patina or causing rainbow-colored reactions.
- 🔬 The cleaning product is a highly refined hydrocarbon distillate, similar to but distinct from kerosene, and is used in conjunction with chemical engineers.
- 💰 The process aims to remove surface residues without touching the coin's tone or surface, essentially 'rinsing' rather than cleaning.
- 🔍 The speaker demonstrates the cleaning process on a dime and a half-dollar, showing the transformation from dirty to clean.
- 🛠️ A new product called 'bu plus' is in trials, which is described as an improved version of an older cleaning product, ms70.
- ✨ A proof gold coin was successfully cleaned with bu plus, demonstrating its effectiveness on high-quality coins.
- 📦 The speaker recommends using air-tight holders and proper storage to prevent residue buildup and environmental damage.
- 🏦 All coins sent for grading are rinsed with the cleaning solution to ensure they are free of surface residue before evaluation.
- 💸 The cleaning solution is affordable and available in different sizes, with the speaker offering assistance after the presentation.
