For over 70 years, Lestoil® has been a leading manufacturer of heavy-duty cleaners, degreasers, and detergents. Our products are specially formulated to cut through the toughest grease and grime to leave surfaces sparkling clean.
Our History

Lestoil® was founded in 1946 by A.P. Alcarese, an Italian immigrant living in Pittsburgh, PA. As an amateur chemist, Alcarese enjoyed experimenting with different cleaning solutions in his home laboratory. One day, after spilling motor oil on his garage floor, Alcarese decided to try creating a formula that could effectively clean up oil stains.
After months of trial and error, Alcarese finally perfected a powerful formula that could dissolve grease and oil faster and more effectively than anything else on the market. He named his creation “Lestoil” as a combination of the words “least” and “oil.”
In 1947, Alcarese founded the Lestoil® Company and began selling his heavy-duty cleaner locally in Pittsburgh. Thanks to Lestoil’s superior cleaning ability, word spread quickly and orders started pouring in from across the country. To meet growing demand, Lestoil® opened its first manufacturing plant in 1948.
Over the next several decades, Lestoil® expanded its product line to include degreasers, detergents, and other specialty cleaners. The company also grew into an international brand by establishing operations in Canada, Australia, and Europe.
Today, Lestoil® continues to be a family-owned business run by Alcarese’s descendants. Though much has changed over the past 70+ years, we’re still committed to A.P. Alcarese’s original vision of creating the most effective cleaning solutions on the market.
