Eucalan is a rinse free formula, releasing dirt and debris from the fibres and into the water. This lends itself to treating the trickiest and most delicate items. 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.
