The Right Way
Is Our Only Way

Peninou is the oldest continuously operating French Laundry in the United States, and we perform all of our dry cleaning and garment services in-house to this day. We still make our own natural starch from scratch. And we hand-finish every shirt with a gentle steam iron, the old world way.


But we also employ the latest innovations in green cleaning


We continuously update our technologies, with custom-made machinery from around the globe. Even our soaps are uniquely formulated to our exacting specifications.

At Peninou, our singular quality has been over 100 years in the making, and we’ve never stopped striving to become even better.


We Also Care For The Environment

  • Largest state-of-the-art, eco-friendly processing facility in the United States

  • Only cleaner endorsed by the Bay Area Air Quality Management District

  • Pioneering environmentally friendly, minimized packaging (on request)

  • Always bleach-free, water softener-free, perfume-free
