Cleaning My Ipod Screen Protector?

I just bought an ipod screen protector. I cleaned the ipod first before putting it on, but i had to redo it several times, and now there are bubbles and bits of hair and dust under it. The package said it was washable, but i’m not sure what that means. Is there any way to clean the adhesive side of the screen protector and put it back on the ipod without bubbles or the adhesive wearing off? Or should i just get a new screen protector altogether?
