We’re sorry to hear that was your experience, Wendy, and we’d like to help! Mr. Clean Magic Erasers are designed to compress and break down as they’re used - like a pencil eraser does, but we still expect them to offer a great clean! How long they last depends on how rough the surface you use them on are, and how often you use them. For best results, always make sure to thoroughly wet the eraser and gently squeeze out the excess rater than twisting the pad. We do also offer the Mr. Clean Magic Eraser Extra Durable for those especially rough and tough messes. Please give us a call at (800) 248-1612 so we can help further.
