Windex Commercial Line Glass Cleaner Trigger Bottle, Blue Original, 32 fl oz

[This review was collected as part of a promotion.] I mean...I've been using this stuff for years. Decades, even, especially if you count all the years I had window washing as one of my childhood chores. It gets the job done, even on tough dog slobber and curious kitty nose marks. I use it on all the mirrors in our house, as well as on the windows. I even use it on the outsides of most of our windows, and it just cuts through all the gross and grime, usually in the first spray-and-swipe, with no lint or residue left behind. They've perfected the spray bottle, too, so it's comfortable to hold and it sprays perfectly, no annoying drips or leaks. I will probably use Windex for the rest of my life. How many products can you say that about? It's a classic for a reason, and it just works.
