Hg descaler for espresso & coffee pad machines is a limescale remover based on citric acid, specially developed for removal of limescale in all kinds of espresso & coffee pad machines. this descaler works safely, quickly & is odour free, as well as being fully biodegradable. When used regularly, your coffee will always be tasty, your espresso or coffee pad machine will work quickly & last longer! pour 75 ml (3/4 coffee cup) of hd decalcifier into the water reservoir & fill it up to 750 ml water (10 x diluted). leave this solution to work for 10 minutes. now switch on the machine & allow half of the solution to run through. switch off the machine, leave to work for 10 minutes & switch it back on so that the rest runs through. rinse at least 3 x with clean tap water after treatment. For coffee pad machines, possibly place a pad holder with a used pad in the machine, to catch any limescale deposits. this will avoid possible clogging of the flow opening. we recommend using hg quick descaler for limescale removal in normal coffee machines, kettles & washing machines. one bottle is sufficient for 6 x treatments.
