Put a ball of foil in the dishwasher. Here’s why

The aluminum foil dishwasher hack gained popularity on platforms like TikTok and Instagram, where users claimed that adding a ball of foil to their dishwasher loads resulted in shinier, cleaner silverware. The idea is simple: the aluminum foil interacts with the dishwashing detergent to help remove tarnish from silver and silver-plated items.

According to proponents of the hack, the foil ball should be about the size of a golf ball and placed in the cutlery basket or on the top rack of the dishwasher. The theory is that the aluminum helps to break down tarnish through a chemical reaction, resulting in sparkling silverware by the end of the wash cycle.
