Yes, you can use HappyFresh even on shorter wash programs. Our formula is effective and works well even on shorter wash programs. We recommend placing the wash sheets among the clothes in the washing machine for best results. This way they will be evenly distributed and provide an effective cleaning of your clothes. P.S It is not necessary to use pre-wash with HappyFresh, which also makes it even more environmentally friendly as you save on water while still getting a good wash result.
