DECAY

This spell decomposes and/or ages an object that occupies less than a 1-foot cube on each side. But it has certain limitations. For example, it can rust a key but cannot break or destroy it. It can, however, rot an apple or turn a scroll to dust. Therefore, that which is deteriorated never ends up disappearing although its state, form and properties change greatly.
This cantrip does not affect the objects that a creature is holding, nor objects with magical properties, nor creatures.
