Wrapping cash in aluminium foil: Why are people putting their banknotes in kitchen foil to protect them?

Wrapping cash in aluminium foil: Aluminium foil can provide an additional layer of protection for banknotes by reducing their exposure to dust and light. However, it does not make the money waterproof. To preserve banknotes effectively, store them in a cool, dry environment, as proper storage conditions are far more important than the foil itself. Keeping cash away from heat and moisture can help maintain its condition over time.
