Urnex Cafiza Espresso Machine Cleaning Powder, 566 g

Using this for my GCP as was recommended by numerous Youtubers. Really good, cleans it nicely. Doesn't seem too strong and keeps the GCP nice and clean if you do it regularly as intended.

Great cleaning. Sparkling shine

This does a good job cleaning portable basket but don’t leave the portable itself soaking. It will go black

FYI, Active ingredient is Sodium Hydroxide or better know as Caustic Soda, DO NOT use on alloy parts such as alloy portafilters and NEVER use as a descaler in your machine. “THIS PRODUCT IS NOT A DESCALER” It’s Safe on Stainless Steel parts only and wear gloves and eye protection. Otherwise it works well, also caustic soda is cheaper to buy.

This is not the cheapest soap for cleaning your Espresso machine, but it is definitely the best. I've used it on every piece of equipment in my coffee set up and it leaves it all sparkling. Remember to clean your machine regularly. If someone, perhaps a lover, were to come over and see that your machine is filthy, it would speak very poorly about you as a provider, a human, and a citizen. To let your machine get dirty is to believe that Democracy requires no work or sacrifice, that it's someone else's problem. A clean espresso machine shows that you are invested in quality, that you will take the time to do maintenance and believe in the long haul. Also this bottle lasts for like 2 years.

does the job - cleans the machine well but you need to follow the instructions precisely

This works like magic. not only cleans your coffee shower and filter, but it can be used to get rid of mug stains.

Does what is expexted.
