I've been using Method washing liquid for years, whilst feeling slightly guilty for the plastic bottle and in the knowledge that liquid is not as good as powder.
However, my liquid is no longer available, so I'm looking for a recommendation for an environmentally friendly washing powder that works. My local refill shop sells Sesu, but I have used their dishwasher powder and I wasn't that impressed. I have previously used Friendly Soap's washing powder, which I liked, but it was too expensive to pay to have it delivered because it was heavy.
What can I use?!?
