I bought this cleaning powder as an alternative to the single-use packets that seemed wasteful. I chose this brand because it was recommended by the manufacturer of my espresso machine (I use a Lelit Mara X, which was a big investment). After some research, I concluded this was a pretty standard choice and didn't think it was worth experimenting with other brands.For dosing consistency, I use the instructions from my machine instead of the ones on the bottle. The bottle’s instructions suggest using a full packet, which can feel wasteful for my needs. So, I wrote a little reminder on the lid: ‘one bag = 1/2 tsp.’ This way, I don't have to keep referring back to the machine manual, and it ensures I’m getting the correct amount without overusing the powder. It’s been a great way to make the powder last longer while still keeping my machine clean.Here's a helpful tip: Both the bottle and machine instructions tell you to pull hot water from the machine to clean the portafilter and basket, but I avoid that. Since the machine takes a while to heat up, you end up using most of the water tank and, in turn, go through your water filters faster just during the cleaning cycle. Instead, I heat water on the stove, which also lets me get a head start while the machine is warming up.All in all, I like the bulk quantity, and the more eco-friendly packaging. It works just as well as the single-use packets, if not better, and it feels like a smarter long-term choice, especially if you're trying to reduce waste. Plus, it saves you from burning through expensive water filters on cleaning alone. It's a solid investment if you’re looking for an effective, sustainable option for your espresso machine.
