We have a wide array of cleaning products available — from descaler to milk frothing cleaner to backflushing detergent — and, admittedly, we sometimes get a little stuck in our ways. Machines with a three-way brew pressure release/solenoid valve (such as the Rancilio Silvia, La Spaziale machines, many of the Ascaso machines and any of the machines with an E61 brew head), require regular backflushing in order to keep that system in tip top shape.
Heretofore we have always recommended powdered backflush detergent — Cafiza or Joe Glo — but when we were meeting with Urnex a couple of weeks ago, they mentioned using the Cafiza tablets for backflushing. And it blew our minds.
Yeah, it doesn’t take much, does it?
If you want to be precise about the quantity of detergent you’re using in your backflushing and cleaning your gear, these tablets are the exact amount you need. Place one tablet in your backflush basket and follow your process as normal; one tablet in a couple cups of hot water is perfect for soaking baskets, portafilters and any other gear you may have that comes into contact with coffee oils and needs a good scrub down.
So what we previously attributed solely to superautomatic brew group cleanliness is cross functional and a great way to easily backflush your equipment without concern of using too much/too little detergent.
