Factors that affect cleaning
|
-type and condition of dirt-water hardness-water temp-surface-agitation or pressure-length of treatment
|
Detergents
|
-penetrates and softens dirt-general-purpose detergent (removes fresh dirt from floors, walls, ceilings, etc.)-heavy-duty detergent (removes wax, aged or dried dirt, baked on grease)
|
Degreaser
|
-dissolves grease-works well on burned on grease (range hoods, oven doors, backsplashes)
|
Delimers
|
-used on mineral deposits and other dirt that other cleaners can't remove (steam tables, dishwashers)
|
Abrasive cleaners
|
Have a scouring agent that helps scrub hard to remove dirt-removed baked-on food-can scratch surfaces
|
Surfaces can be sanitized using:
|
-heat (immerse in water that is 171 degrees for at least 30 secs)-chemicals (chlorine, iodine, quats)
|
If using a detergent sanitizer blend?
|
-use it once to clean and then again to sanitize
|
Sanitizer effectiveness is affected by:
|
Concentration, temperature, contact time, water hardness and pH
|
How to clean and sanitize a surface:
|
Scrape or remove food-wash-rinse-sanitize-allow to air-dry
|
How to clean and sanitize equipment:
|
-unplug-take off removable parts-scrape or remove food-wash-rinse-sanitize-air-dry-put back together
|
Clean in place TCS food:
|
Must be cleaned and sanitized every day unless indicated otherwise
|
Final sanitizing rinse must be at least what temp for high temp dishwashers?
|
-181-165 for stationary rack, single temp machines
|
3 compartment sink:
|
-first--detergent wand water at 110--second--clean water-third--water and sanitizer --scrape, wash, rinse, sanitize, air-dry
|
Wet wiping cloths
|
-for wiping counters and other surfaces-store in sanitizer solution between uses (change when necessary)-keep cloths that contact raw meat, fish, and poultry separate from other cleaning cloths
|
Dry wiping cloths
|
-used to wipe food spills for tableware, must be kept dry while in use, must not contain food debris or look visibly dirty
