A Steel Wood Pack is used for washing pans, plates & silverware. It makes an appearance in Diary of a Wimpy Kid: Cabin Fever when Manny puts Greg's bumper sticker award in the middle of Frank's new sports car. Greg gets scared that Frank would punish him, so he uses a sponge to scrub off the sticker. After discovering the steel pads, he uses them to scrub off the sticker. He also washed the whole car with it. He gets a shock after rinsing the car. It scrubbed off the paint too. After replacing the color with permanent marker, he replaces the bumper sticker's mark with a note in Susan (Mom)'s handwriting. But before he could, Frank saw it and was angry at Greg, but Susan took Greg's side by saying that the sports car was no good and he should buy a mini-van.
