I use this for my automatic machine descaling DeLonghi for 2 years without any problems. I initially chose the product recommended by the mark by security concern on my machine and since I continue since it is satisfactory and I have not found better. It is suitable for all descaling coffee machines, whatever their mode or their brand. Its ecological formula is positive that this product is not harmless either. The 500ml bottle allows 4 cleanings. The marks on the label of the bottle indicates the ideal amount to be paid. The smell is detectable only if it puts its nose above and the bottle is equipped with a safety cap. My machine is fully descaled every time and I can not find special taste of coffee just after. Although there was an expected rinsing after descaling, I play safe by cleaning and rinsing again the water tray. The price of 11.29 is more than interesting because it happened to me to pay that descaling up to 19 on the site where I bought my coffee machine.
