Mayonnaise can clean pennies due to its acidic ingredients, such as vinegar and lemon juice, which help dissolve tarnish and oxidation on the coin's surface. The oil in mayonnaise also acts as a lubricant, allowing for easier removal of grime. To clean a penny, one can apply mayonnaise, let it sit for a short period, and then gently rub or rinse it off for a cleaner appearance. However, this method may not be suitable for valuable or collectible coins, as it could potentially damage their surface.
