Breaks down the rubber gasket on E61 brew headReview by Derek
Price Value Quality
Although this cleaning powder does a fantastic job of dissolving caramelized, solid coffee crud quickly and easily, making your coffee machine sparkle again, it has one drawback. Each time I use it in my brew head, I notice the wash water (meaning the cleaning powder and water mixed together) turns black. This blackness appeared to be due to the black, brew head, rubber gasket breaking down or dissolving. And, upon removing and handling the rubber gasket from the brew head (on our Rocket Cellini machine) I found that I can encourage more blackness by even rubbing my fingers over the wash water soaked rubber gasket. Not good. At first I thought it was because the rubber gasket in my E61 brew head was simply getting old. However, after thoroughly rinsing the gasket in fresh water I could no longer encourage black rubber material to be dissolved from the gasket simply by rubbing my fingers over it. So, this confirms that the wash water solution is somewhat harmful to the gasket and that's the reason for the 3 star rating.
If you don't have any rubber material to contend with, I say go ahead and use this cleaner as it is extremely powerful, dissolving all traces of coffee crud, making your machine sparkle.
However, if you are using this to clean an espresso machine with a gasketed brew head, I would advise NOT to follow the supplied instructions for a quick cleanup simply by placing a 1/2 teaspoon of cleaner in your blind portafilter and backflushing. I don't believe this will adequately rinse out the dissolved rubber gasket material sufficiently - which means disassembling the brew head for each cleaning.
