Cleaning Pennies Tips

Look for Flamed Cheetos or Hot Cheetos. Drop 2 or 3 cheetos in a baggies,the penny, add a cap full of water or about 1 teaspoon, and seal the baggie. The cheetos will soak and get soggy,(looks yucky), but almost immediately it will start cleaning the penny. Works great in my science experiements. Cleans pennies within minutes.
Another method I use is a product the kids buy as a candy called
Sal and Limon and or Lucas. Do the same proceedure except
use very little water. Almost like a cap full and presto.
With in seconds the Sal and limon cleans the penny. If
you leave in there too long, it will eat the image on the
penny.
