How long is the life span of a PIMP pad?

A PIMP typically lives for 5-7 years. However, its longevity can be shortened if you usually wash a pad more than once during a cycle. Washing is often more stressful to cloth than wearing. If you don't need to wash and reuse any pads mid-cycle, your collection will last for years and years. You'll probably be lusting after some new, fabulous pattern long before any of your PIMPs bite the dust.
