Laundry Oops

Have you ever washed your clothes only to open the washer to find the clothes dirtier than when you started? I did that today. I had been throwing dish towels, bibs and other miscellaneous items in the wash throughout the weekend, and when I topped it off with some dark clothes, I totally missed the box of plastic wrap that had fallen in from the shelf above. After the wash was done, I opened the lid and found pulverized cardboard ALL OVER THE CLOTHES! I found the serrated edge tangled up in a dish rag, and a strip of plastic wrap wadded up with the clothes. What a mess!! Even Shaklee laundry detergent is no match for a cardboard box.
Note to self: check the washer before putting anything in it.

What have you washed by accident?
