Science explained

How soap and detergents work

Surfactants have molecular regions that interact differently with water and oily substances, helping detach and disperse soils.

Amphiphilic structure matters

Many surfactants have a water-attracting region and an oil-compatible region.

Micelles can trap oily material

Above suitable concentrations, surfactants can organize into structures that carry hydrophobic material in water.

Mechanical action still helps

Agitation and rinsing move loosened material away.

Do not mix cleaners casually

Cleaning products can contain reactive ingredients beyond their surfactants; follow product labels.
