Very carefully.
Yes windex can clean a penny, I did a science project on it in 8th grade, and windex cleans pennies better than salt water and vinegar. It cleans a penny because it has ammonia in it which can cause some sort of chemical reaction with the copper which in turn keeps the penny clean
no
well 180 pennies per pound so 180*4 would be 720 so yes 720 pennies for 4 pounds
yes it does but it does not make penny shiny i have tried it but it just get the dirt of so really does not work
Salt and vinegar make a penny nice and shiny.
Yes it will clean a penny but it won't make it shiny
