I seen a very simple way once .. get some regular tape , like scotch tape , the simple stuff u wrap presents with.. clean the screen really good with a good glass cleaner .. now place the tape on the screen making sure to over lap & long enough so it hangs off the edges.. this will trap any dust after you have cleaned it really well.. now peel the tape off & then immediately place your new screen protector on 🙂 .. hope this helps
