Can all-purpose cleaner damage interior surfaces?

Yes, if it is too concentrated or used on the wrong material. Strong dilutions can discolor plastics, dry out leather, remove coatings from screens and leave residue that attracts dirt. Dilute according to the label for interior use, spray onto a towel or brush rather than directly onto electronics, wipe residue off with a damp towel and test on an inconspicuous area first.
