Our Story
We engineer scientific, material-safe solutions to preserve the structure, color, and legacy of your most valued headwear.
— The Origin
In 2024, two collectors with 400+ caps between them got tired of watching grail pieces fade, warp and yellow from the wrong cleaners. So they pulled in a chemist friend and started mixing.
Three years and 187 prototypes later, the Cap Sauce system was born — a complete ecosystem of foam, protector, deodorizer and tools, formulated for every fabric a cap is ever made from.
We don’t sell laundry detergent in a shiny bottle. Every formula is built from scratch in our California lab, tested on real hats from real collections, and only ships when it earns a spot in our own rotation.
— Our Values
Four principles that guide every formula, every package and every email we ship.
Every formula is built from scratch and tested on real hats — never reformulated white-label products.
Plant-based surfactants, recyclable packaging and refill program. The planet deserves a clean cap too.
187 prototypes for the foam alone. We don't ship until the lab and our collection both approve.
We build for the people who care about the difference between a 1996 fitted and a 2024 reissue.
