Eucalan’s formula doesn't require that it be rinsed. With your first soak in Eucalan, you should likely see the water in the wash basin turn a bit brown. The soap releases dirt into the wash basin, & though the clothing absorbs a little of the soap, it is beneficial. Lanolin fortifies & conditions clothing fibres; This is particularly great for woolens & knits but can be used on most anything.

Eucalan’s no-rinse formula is also convenient – great for travel when you’re not likely to have a washing machine or are seeking to conserve water.
