When cardboard is exposed to water, it becomes weaker and softer. The water breaks down the fibers in the cardboard, leading to a loss of structural integrity. Over time, cardboard will disintegrate if left in water for a prolonged period. If you need to dispose of wet cardboard, it's advisable to dry it out for recycling or compost it, as wet cardboard can attract mold and pests.
