No. The orange juice has CuO which cleans the penny by dissolving the rust off of it.
Nope! Sorry. Water will not clean a penny. If a coin stays too long in water, it might rust.
no
If they are an alloy, they will eventually rust.
How long will it t take a quarter to rust in fresh water
A penny can take anywhere from a week to a month to fully rust with just rust, I've seen pennies with mold and that took two weeks, but it could finish sooner, with mold it could take anywhere from four days to three weeks.
A British penny is not normally affected by rusting .
i think the vinegar will un rist a penny
