Anhydrous Citric Acid

The natural descaler of choice to use in Home Espresso Machines.   It is a mild acid, a bit more aggresive than vinegar, food safe, and won't harm the metals or seals in your machine - EXCEPT CHROME - DO NOT USE ON CHROME (for Chromed parts, we use Joe Glo!). 

We sell these pure crystals in 100 gram units (about 1/4 lb).  This quantity is enough for about 10 routine, maintenance descalings of a Home Espresso Machine.  You would use more in extreme cases.   We are offering this quantity because it's more than enough for the average person to use over the course of a LONG time, and it does have about a 2 year shelf life (keep it dry!).    Simple to use - and no additives.

Instructions for use:  Dissolve 1 Tablespoon Citric Acid Crystals in 1 Liter of hot water, add to empty espresso machine boiler, add water to fill to the top.  Close boiler.  Cycle Element till hot.  Operate group, steam & water valves to allow liquid to pass through.  Cool.  Empty boiler.  Rinse several times until water from the machine remains clear.  Don't be alarmed if the water/citric solution turns blue/green/milky colors - this is normal.  Rinse very well before using the machine.

TECH TIP:   Before you descale, LOOK INSIDE THE BOILER...check for white patches of scale by using an inspection light.  Avoid descaling if it is not actually needed.
