I had problems with my Senseo machine, so I thought buying times the originals product of Senseo. Has really works great, but on closer inspection of the ingredients you can see that it's just 100% citric pay determined not man gets even with the use of standard detergent in the supermarket and as man has 10.99 for 400 grams. It's almost usury only because there Senseo draufsteht, dissolve so just 100 grams of citric acid in hot water and the Senseo descale so that 100 grams should be divided between two tanks of fuel. So take the normal product from the supermarket and save money !!!
