Do Cleaning Chemicals Clean As Well After They Have Been Frozen
Problem:
The researcher is trying to determine whether or not cleaning materials
will clean as well if they have been frozen solid and subsequently thawed out
until they have returned to a liquid state of matter.
The researcher will use Dial Antibacterial Kitchen Cleaner, Clorox
Bleach, and Parson’s Ammonia, applied to simple bacon grease, to determine which
chemical is least affected by the glaciation.
Hypothesis:
The researcher feels that the process of glaciation will degrade the
ability of these three household cleaning chemicals to breakdown the most common
kitchen cleaning problem – grease.
For example, the freezing, thawing, and then freezing again of ice cream
puts the substance through the freezing process. The result is a separation of
heavy and light substances which breaks down the food. The researcher feels that
the same end result may happen with the cleaning materials.
Experimentation
Test Concept:
In order to determine weather the glaciation process affected the
cleaning chemicals, it is first important to establish its potency prior to
freezing. Accordingly, two test sets were created by the researcher. The purpose
of the test was to determine how well the chemicals could break down household
grease before and after the substances were frozen. The first test set would
focus on unfrozen chemicals, while the second was set up for previously frozen
chemicals.
The Test:
To start the experiment the researcher fried four pieces of bacon until
there was enough grease in the skillet to perform the test. He then put a
quarter teaspoon of the grease onto two nine by thirteen casserole dishes. Each
casserole dish was set up for three frozen and three unfrozen chemical cleaners.
A measured amount of cleaner (both frozen and unfrozen) was added to each spot
of grease. After approximately two minutes of breaking down the grease, the
dishes were raised to a uniform height at one end and the broken down grease was
allowed to run. By measuring how far the grease ran, the researcher could then
determine how much the cleaner broke down and therefore which cleaner was
affected by the glaciation.
Resources
The resources for this experiment were acquired from the labels of the
chemicals. Research was also done to try and find information about Chlorine in
the Clorox Bleach but ended unsuccessfully. There was also research done to find
out about the reason the 409 degreaser performed so poorly.
Conclusion
The researcher has concluded that the previously frozen chemicals performed
just as well if not better than the unfrozen chemicals. See charts one and two
