Why Soap Works So Well for Washing Up

Soap works by binding to oils and fats. One end of the soap molecule attaches to grease while the other attaches to water, allowing cooking oils and food residues to be lifted from surfaces and rinsed away.

Traditional Marseille soap is particularly well suited to this task because it is made from vegetable oils that produce a stable, effective cleaning soap when saponified. For this reason it has long been used not only for washing hands and laundry, but also for cleaning cookware, dishes and kitchen surfaces.

Solid Dishwashing Soap: A Traditional Kitchen Staple

Solid dishwashing soap bars remain widely used across France. A sponge or brush is simply rubbed directly onto the soap before washing dishes.

Because the soap is concentrated in solid form, these bars last a long time and avoid the need for plastic bottles. Many are enriched with bicarbonate of soda to support grease removal and help lift stubborn residues from pans and cookware.

For households looking to simplify their cleaning routine, solid dishwashing soaps offer a durable and economical alternative to conventional washing-up liquids.

Marseille Soap Washing-Up Liquids & Traditional Dishwasher Powders

For everyday convenience, many savonneries also produce washing-up liquids based on their traditional Marseille soap formulations. These liquids combine the natural degreasing properties of vegetable oil soap with the familiar format of modern dishwashing liquids.

Dishwasher powders take a different approach, using mineral cleaning agents such as sodium percarbonate and soda crystals. These traditional ingredients release active oxygen during washing, helping break down grease and food residues while supporting dishwasher maintenance.

Together, these formats reflect the continuing evolution of traditional cleaning methods — simple formulations designed to work reliably in everyday kitchens.
