Windex • S. C. Johnson
Some time ago, trying to be helpful, I offered to clean my buddy’s stove top. After scraping off six years of burnt pan overflows, and scrubbing what a paint scraper missed, it was time for finishing touches. Windex® and a clean towel. Gonna bring his stovetop back to factory specifications!
“It’s under the sink”, I’m told. Well, there was a spray bottle of purple stuff 
labeled Glass Cleaner. It did nothing to remove residue and grease. Discount cleaner strikes out. Purple water without a trace of ammonia or isopropyl alcohol. Sold for a buck. Not worth one thin dime.
Never do I buy a glass cleaner unless it is the original. Windex®. Proprietary formula and all that industrial secrets stuff cannot be imitated. I’ve concocted a close imitation, but it does not hit the high mark S.C. Johnson has established. The inimitable go-to cleaning product trusted by generations. Often copied, never duplicated.
In 1933 Harry R. Drackett invented “Windex” as nearly 100% solvent. ATB loves harsh chemicals to get a job right, but the Sam Wise formula patented after WW II is what we currently come to love as Windex. And non-toxic biodegradable formulas? Whole Foods and Trader Joe can keep that foo-foo stuff. If you want to clean glass instead of smearing around dirt, go to the original. Windex®
