- Real-time USPS shipping rates at checkout
- Ships from Lyndhurst, NJ in 1–2 business days
- Lifetime-guaranteed Power One dispenser
This is the bottle that does the heavy lifting: one 3.55 L jug delivers around 710 hand washes — roughly five cents each — so a busy household, shop or office stays in clean hands for months on a single refill.
The cost-per-wash math
At about 710 washes per bottle, the 3.55 L works out to ~5¢ a wash — a fraction of what you pay buying little bottles over and over. Because Power One is a true concentrate (only ~20% water), one metered pump is all you need, so the bottle stretches far past what its size suggests. If you're outfitting more than one sink, run the numbers in our bulk hand soap buyer's guide.
What's actually in it
Nearly 20% real walnut-shell scrubbers cut heavy grease, paint, ink and ground-in grime — the reason it's a favorite in garages and on job sites (more in best hand soap for mechanics). There are no petroleum solvents, and six skin conditioners keep hands soft on high-wash days. It's USDA Certified Bio-Based at 70%+ content.

The 3.55 L refills any foam or liquid dispenser you already own — top off and go. Want zero waste? Our lifetime-guaranteed wall dispenser loads the bottle upside-down so gravity draws out every last drop, or grab the 3.55 L + dispenser set to start from scratch.
