Reduce your plastic packaging even further. Our big 3L bulk pack contains seven times more detergent than a single standard refill pack. In addition to plastic savings, our bulk is more efficient on your hip-pocket. Fill your empty dispenser bottle with our refill pack, which you can send back to us to be refilled and reused, for free! These refill packs are filled with the dependable hero of Dirt, our 8x eco concentrate laundry detergent. Formulated with 100% pure and powerful plant-based and biodegradable ingredients. It's the cleanest choice; for your clothes, your skin and the environment. Washing precious fabrics? You'll want our wool & delicates wash instead.
