Several years ago my sister had a fuss with her husband and wanted to know if she could come and spend the night at our house. I said yes of course. I had just finished putting the binding on a quilt I had hand quilted and pieced. I tucked her in that night on our couch with my newly finished quilt. She had brought her own pillow, jammies etc. To make a long story short, when she tossed her pillow and other things into the back of her station wagon, there was a battery back there. The battery acid got onto my quilt on one of the blocks and part of the sashing and ate little holes in it. I never told her of the damage, it was an accident. I still have the quilt, its one of my favorites.
