Origin Story

The Man Behind the Diamond

The story of Charles J. Ottenheimer — and the seven-year pursuit that became Diamond Magic.

The Beginning

Charlie Puka-Pau

Charles J. Ottenheimer — known throughout the Hawaiian Islands as "Charlie Puka-Pau" — was the inventor and developer of Diamond Magic.

Charlie arrived in Hawaii in 1984 and dedicated himself to the craft of glass care. Over the years, he personally repaired more than 25,000 windshields and removed water spots and stains from thousands of automobiles across the islands.

From the very beginning, Charlie received hundreds of requests to remove water spots and mineral stains from automotive and building glass. But no existing solution met his standard — fast, safe, effective, easy to use, and non-toxic, all at the same time. So he set out to create one himself. Founded in 1999, Diamond Magic has since evolved into the ultimate multi-purpose solution, replacing dozens of specialized cleaners with a single, high-performance formula.

For seven years, Charlie experimented with over 1,700 abrasive combinations sourced from America, Japan, Belgium, and Germany — testing more than 100 different materials before discovering the formula that would change everything.

The Breakthrough

Born from Craftsmanship

After testing over 100 different abrasive materials, Charlie discovered that sub-micron particles of diamond dust, suspended in a compatible cleaning paste, created a synergy that could scour and polish glass and hard surfaces like nothing else on the market.

That discovery became Diamond Magic — a product born from real craftsmanship, relentless experimentation, and a refusal to accept "good enough." What started as a water spot remover evolved into a multi-purpose cleaning product trusted by professionals across 20+ countries worldwide.
