In regular or high efficiency machines, use 30 ml for a STANDARD LOAD that is LIGHTLY SOILED. For LARGE LOADS or HEAVILY SOILED clothes use 60 ml.
To hand wash a few SMALL ITEMS or DELICATES add 15 ml to a sink full of water and hand wash as usual. Note that you will not get suds as this is a natural detergent formulated for HE MACHINES.
For STAINS or HEAVILY SOILED SPOTS mix 30 ml of detergent with 15 ml of water and make into a paste, then rub on the soiled area, use a bristle brush to get into the fibers, then rinse with water before laundering as usual.
