Milk solids deposits - These are often termed "milk stone" and are the
hard deposits left on inadequately cleaned milking equipment. These
deposits appear chalky and are very difficult to remove without the use
of proper chemical cleaning methods. Routinely using ________
_______________ will help prevent the buildup of milk solids on the
milk equipment.
Water mineral deposits - Hard water, or water with excessive
amounts of minerals, tend to cause discolorations or even leave
"crusty" deposits on milk contact surfaces. These deposits will inhibit
effective cleaning procedures and adjustments to the chemical cleaners
or installation of water softeners will help alleviate the problem. These
deposits are best removed by using acid washes on a regular basis,
recommended use following each chlorinated alkaline cleaning.
High iron content water - Water high in iron will stain surfaces and
cause cleaning problems. Use of chemicals, specifically, acid rinses,
will help dissolve these deposits.
