My 6 yr old dd has always had a hard sandwich box before now which is lovely to clean. However, she fell in love with a softer type one with a long strap. I opened it this morning and is stinks. I have cleaned it with hot water and a cloth but it still seems to be the same. The thing is there is stitching inside and there are bits of food debris stuck there which is obviously decaying and causing the whiff.
Is there a better way to clean it? I dont think it will withstand the washing machine.
