We had a cappuccino machine, I thought my wife kept cleaning the crispy dried milk off the steamer spout, she thought I was doing it. A year later, after coffee every morning, we found out the cat was licking it off when we were at work.
Maybe it was my obsessive wand purging or just luck, but I never had one clog. The heads had to be descaled manually once but that was because the owner forgot to clean the water filter. From then on I had it on the to do-list myself.
