What do manual, semi-automated and automated cleaning have in common?
Cleaning
requires both physical & chemical
processesSlide4

brief review of formulated cleaning agents and their application
Selection of Cleaning Agents & Coupon TestingSlide10
What Chemicals Work Best?
80% of soils will be cleaned with an alkaline cleaner
10% will be cleaned with an acidic cleaner
10% will use either enzymatic, emulsion or solvent-based cleanersSlide11
Bench Coupon Evaluation Process
Clean and
passivate
coupons
Coat coupons with soil
Prepare detergent in a beaker with magnetic stir
bar
Place coupons in beaker and place on hot
plate
Evaluate coupons in beaker Slide12
What Do You Learn From A Bench Evaluation?
T
ime
. The
time it takes to effectively remove the material from the coupon
A
ction
. Identifies degree of action required, heavy or slight
C
hemical
. Determines
the best formulated cleaning agent per product, along with starting point use concentrationsTemperature. Determination of the optimal temperature needed for product removalSlide13
Water Hardness Influences Cleaning Action
A detergent’s effectiveness is reduced when used in hard water.
Hardness in water is caused by the presence of mineral salts
.
Calcium (Ca)
Magnesium (Mg)
Iron (Fe)
Manganese (
Mn
)
The
mineral salts react with surfactants to form an insoluble precipitate known as soap film.Hardness may be unavoidable based on where you live, but you can soften your water to reduce hardness.
