Heritage & History
Stoner Inc. was founded in 1942 and has spent more than eight decades developing cleaning and release agent products for industrial and consumer applications. The company entered the automotive care market with a focus on glass cleaning, identifying windshield clarity as a safety-critical need that existing general-purpose glass cleaners addressed poorly. The resulting Invisible Glass formulation — streak-free, residue-free, and effective on automotive glass curved surfaces and tinted films — became the company's signature product.
Invisible Glass grew to become the number-one selling automotive glass cleaner in the United States, a position built on repeat purchases from drivers who experienced the difference between a product engineered specifically for automotive glass and a household glass cleaner pressed into automotive use. Stoner expanded its car care lineup to include interior detailers, tire dressings, and paint care products, all manufactured in the USA.
Made in the USA
Stoner Car Care products are formulated and manufactured in the United States, consistent with the company's eight-decade history of domestic production. The Invisible Glass formula is produced to tight consistency standards — the streak-free result that built the product's reputation depends on precise ingredient ratios and manufacturing quality control that Stoner maintains at its US facility.
The automotive aftermarket is a category where American drivers spend significant money annually on products that vary widely in effectiveness. Stoner's domestic manufacturing allows for quality oversight from raw material selection through finished product packaging, and the Invisible Glass track record across millions of vehicles has validated that approach. The brand's longevity in a competitive market reflects the durability of a reputation built on a product that genuinely performs.
