Flitz

Flitz International, Ltd. is a Waterford, Wisconsin manufacturer that built its reputation on one core product: a concentrated paste that cleans, polishes, and protects virtually any polishable surface. The brand's "Made in USA with German ingredients" positioning reflects its founding chemistry lineage — the formula has been refined for decades and remains essentially unchanged, which is itself a quality signal in a market where reformulations are common. The automotive and detailing community treats Flitz as a utility staple rather than a prestige product — it appears in garage kits alongside more specialized compounds because its surface range (chrome, stainless, aluminum, fiberglass, painted surfaces, plastics) means it fills a role that multiple single-purpose products otherwise would. Marine and outdoor-equipment communities have similarly long institutional memory of the brand.
