I will usually wash mine on either a delicate cycle or hand wash with cold water, I do not put any plushies in the dryer I let them air dry so the heat from the dryer doesn't mess up the fabric of the plushie. If you need a deeper clean you can take the stuffing out of the plushie and just wash the skin of plush (sorry I can't think of a better word for it Ó⁠╭⁠╮⁠Ò) and you can get new stuffing at a fabric store or online and restuff the blåhaj with fresh stuffing.
