Packing Tape Machine

Hello, I return to school tomorrow and my backpack was the old tape on him. I want to use it, but it is really dirty. Please! Is it safe to wash my backpack?

Did you tape Extra
then you can replace all, if there is a problem or just wash in the bathtub with hot water and soap
Oh, and clean the tub when you finish

The duct tape would probably collapse in the washing machine. Hit Mom or Dad for money and buy new. Do not forget to pay them.
