Solid Bar Laundry Soap

Solid Bar Laundry Soap — One Bar, No Bottle, Zero Waste

A solid bar that does the job of a whole jug of detergent. Grate what you need, dissolve it in warm water, and wash — it’s the oldest laundry trick there is, and it still works. Handcrafted at Monticello Soap Company with clean ingredients you can actually pronounce.

What You’ll Find in This Collection

Our Solid Laundry Soap Bar, made in small batches in the Monticello workshop. Grate it into hot water for a liquid detergent, rub it directly on collars and cuffs as a pre-treat stick, or shave it into a homemade powder blend. One bar goes a remarkably long way.
