Claims28
A method of cleaning soiled food or beverage manufacturing and handling equipment comprising:
- a cleaning step in which the surfaces of said equipment are contacted with a cleaning solution comprising a non-chlorine detergent composition;
- and
- a post-rinsing step in which said equipment surfaces are rinsed with a rinse solution thereby removing residues of said detergent composition remaining on said equipment,
- wherein the surfaces of said equipment have not been pre-rinsed prior to said cleaning step.
A method of cleaning soiled food or beverage manufacturing and handling equipment comprising:
- a cleaning step in which the surfaces of said equipment are contacted with a volume of a cleaning solution comprising a non-chlorine detergent composition, wherein said volume of cleaning solution is circulated through said equipment for a period of time to effect a reduction of the soils on said equipment surfaces;
- a post-rinsing step in which said equipment surfaces are rinsed with a rinse solution thereby removing residues of said detergent composition remaining on said equipment;
- and
- a pre-rinse step in which a volume of pre-rinse fluid is circulated through said equipment prior to said cleaning step wherein the volume of pre-rinse fluid used is less than 50% of the volume of cleaning solution used in said cleaning step.
