Always use the appropriate descaler for your machine, 11 Oct. 2010
Different manufacturers use different seal and tubing materials in their machines. These can be damaged by using the wrong descaling solution. A friend of mine recently wrote off his rather expensive Krups automatic by using cheap kettle descaler - it's not worth the risk. I have a Gaggia, so used this descaler, which (unusually) is Lactic acid based. It seemed to work fine and left no discernible taste in the machine. No complaints.
