Less laundry detergent still gets clothes clean
This one helps the budget and the planet all in one. The recommended scoop (or squirt) size for laundry detergent is far too much. Identical cleaning results can be obtained with 1/3 the suggested amount. You'd even be surprised how clean laundry gets WITHOUT soap - although children's clothes do get exceptionally dirty. Using less detergent lets you save money and puts fewer nasties (like phosphates) in the water.
