Formula 409 is a brand of cleaning products that includes an all-purpose cleaner, glass and surface cleaner, carpet cleaner, and many others. It is an antibacterial cleaning spray that cuts through greasy, germ-filled messes to leave household surfaces clean in every room. The flagship product was invented in 1957 by Morris D. Rouff, whose Michigan company manufactured industrial cleaning supplies. The name Formula 409 is a tribute to the tenacity of two young Detroit scientists who formulated the greatest grease-cutting, dirt-destroying, bacteria-cutting cleaner on the planet. It wasnt until batch number 409 that they were finally satisfied, and so the name stuck. The antibacterial formula quickly cuts through grease and grime and disinfects as you wipe, killing 99.9% of germs, including the COVID-19 virus.
