3.5 CLEANING DISASSEMBLED PARTS

Disassembled machine parts require complete cleaning,
sanitizing and air drying before assembling. Local and state
health codes will dictate the procedure required. Some
state health codes require a four sink process (pre-wash,
wash, rinse, sanitize, air dry), while others require a three
sink process (without the pre-wash step). The following
procedures are a general guideline only. Consult your
local and state health codes for procedures required in
your location.
