Both, had debris in between the piece you peel off and the protector it self, so no matter how much you cleaned the Switch (Shower trick really does help)

While I did not try the steamy shower trick, I would HIGHLY recommend an area that is not dusty (where can we find one of these in our busy lives, huh?).

Didn't make the same mistake again by hoping the hot shower trick would work

I did the whole heated shower trick to no avail

It comes with 2 protectors but only used one the shower trick worked well

error.)Don’t trust everything that has tons of positive reviews
