Dirty Window Panes

This is just my opinion. There a a couple of problems using Metho!!! Firstly when using metho even though you have diluted it, you are leaving a chemical residue on window or sliding door surfaces. We all know kids do not use handles to open sliding doors so therefore when they touch the window they are making contact with the chemical...later when they eat something & lick their fingers they will also be ingesting it. Also it is not advised to use metho on tinted surfaces as it will damage the tint. Shine a light on the window at night after cleaning a tinted window & see what damage the tint has done. There are chemical free/easy to use ways to clean windows leaving them streak free. I hope this helps & I hope that I have not offended anyone.
