Granite Gold Inc. is a family company with a long history of stone care expertise that spans three generations, dating back to the 1950s. Co-founders and cousins Lenny Sciarrino and Lenny Pellegrino grew up in the family business, manufacturing, installing and restoring stone surfaces in homes and businesses throughout Southern California.


Granite Gold Inc. has become a leading brand name in the United States. Since the early 2000s we have been designing a range of high-quality natural-stone care products in Southern California, which later expanded across all major cities in the U.S. and internationally.

The company was co-founded by cousins Lenny Sciarrino and Lenny Pellegrino, who grew up installing and restoring natural-stone surfaces in Southern California. It is because of their expertise Granite Gold Inc. began with such great success and continues to thrive today.

To this date, Granite Gold Inc. has produced a wide variety of stone surface cleaning, sealing, and polishing products, including daily cleaners, refills, and wipes.

While the Lennys were in the family businesses manufacturing, installing and restoring stone surfaces, time and again, customers would ask “What should I use to clean my stone?”
There really wasn’t anything in the market they could recommend with confidence. Common household cleaners will damage natural stone, and anything marketed specifically for use on stone either left streaks and fingerprints or wasn’t readily available for our customers to easily purchase. Mild dish soap and water was all the cousins would recommend, and it still wasn’t the best answer.

They began experimenting in the late ’90s to find an answer to customers’ questions, and a few years later came up with a solution that was safe on all stone surfaces since they vary in porosity and density and would not streak or leave fingerprints.

With the answer in hand, the cousins were filling bottles and handwriting “Cleaner” or “Polish” on them, giving them away after finishing restoration and installation projects. That soon led customers returning, asking for more of the magic formula. Granite Gold Inc. was formed in 2003, and in 2004 the Lennys set out to bring Granite Gold® brand stone-care products to a mass consumer audience.

They started small with local distribution in the San Diego area and going on the road with how-to demonstrations at regional home and garden shows and in Costco club stores. Then, in 2005, the cousins led a national consumer awareness campaign on the dangers common household cleaners pose to natural stone surfaces. That catapulted word of mouth and online sales in Granite Gold®’s early days, and soon after the cousins recruited consumer packaged goods expert Scott Martin, Granite Gold®’s chief operating officer, who had spent 16-plus years building global sales and distribution at WD-40 Company and rising through the ranks to senior vice president of global sales.
