Good for SO MUCH MORE than just espresso machines! Anything coffee can be clean again.
This stuff is awesome! And it's not just for espresso machines. We use this to clean everything coffee related - from airpots to travel mugs to coffee pots. All of that stuff needs to stay clean in order to get the best coffee flavor.
If you're using it for an espresso machine, simply put about a tablespoon of the powder in your backflush filter and run it for about 15 seconds. Then rinse the filter and backflush the machine three of four times until the water runs clean.
For any of your other coffee equipment, just put about a tablespoon of Cafiza powder in the mug, carafe or whatever and fill it with hot water. Let it sit for about 10 minutes and then rinse it clean. You'll be amazed at how clean your equipment is once you're done.
