The head should not be lifted behind the ears, only the whole. Please watch your eyes, protect them from getting wet, they are painted.
I do not recommend washing suits with washing machine. You can carry your paws, tail and footpaws to the dry cleaners, they should perfectly deal with artificial fur.
Your head can be refreshed with dry shampoo, no baby talc (you have to brush your fur thoroughly, preferably with an animal brush or comb). You can also make a disinfectant, or buy it. They are sold on Etsy, or you can search for people who produce them on Furry groups.
