Arm & Hammer 2X Concentrated Laundry Detergent, Clean Burst
I love this. It’s easy to carry (i.e., doesn’t weigh one metric ton). It’s biodegradable and the container is recyclable. And the scent smells “clean”, unlike some detergents which smell too sweet in my opinion. Basically, your clothes go in smelling questionable (or at least mine do) and they come out as Jesus Christ.
You may be saying, “Ok, cool, but it’s just detergent”. True! Buuuuuuut, simple products with low environmental impact that work well are hard to find. If you’re ever in the market for a new laundry detergent, I wholeheartedly recommend this one.
