You can’t shine silverware by soaking it in mayonnaise.
In fact, mayo can dull knives and stain some metals if left on them too long.
However, some people swear you can use it to polish furniture and moisturize skin.
Mayonnaise is commonly served in a sandwich, or with salad such as potato salad or canned tuna.
It’s best used with food.
For example, in Western Europe, mayonnaise is often served with French fries or chips.
