PURPOSE
The purpose of this project was to find out which brand of carpet cleaner removed stain most efficiently.
I became interested in this idea when I watched competing carpet cleaner commercials that all claimed to be the best, so I wanted to find out which really was the best.
The information gained from this experiment could inform consumers about which brand of carpet cleaner would be the best choice to remove their carpet stains best.
HYPOTHESIS
My hypothesis was that Resolve brand would remove the stain best.
My hypothesis was that Resolve brand would remove the stain best.
I based my hypothesis on a science project that was done by Bryanna Bruskland in 2002-2003. Her project title was “The Effect of Carpet Cleaners on Stain Removal”. She said that the whiteness was highest when using Resolve brand.
The constants in this study were:
• Type and color of carpet
• Stain mixture
• Amount of stain used on carpet
• Size of carpet squares
• Drying time
• Amount of carpet cleaner applied
• Method for using cleaner
• Method of measuring stain removal
The manipulated variable was the brand of the carpet cleaner.
The responding variable was the amount of stain remaining on the carpet.
To measure the responding variable, I used the colorimeter at a local lab to determine the whiteness of the carpet squares.

PROCEDURES
1. Collect all materials.
2. Mix stain.
a. Get large bowl.
b. Make 350 ml of black coffee.
c. Mix 350 ml black coffee and 250 ml grape juice in bowl with wooden spoon.
3. Cut
carpet squares
a. Purchase white carpet.
b. Cut into 21 10x10 cm squares.
4. Stain carpet.
a. Take 10 ml stain from bowl with dropper.
b. Slowly drop onto center of one carpet square.
c. Rub into carpet with finger for 15 seconds.
d. Repeat steps B and C on 18 carpet squares (but leave three control squares unstained).
5. Clean stained carpet.
a. Apply 1.4 ml of cleanser of stain on one carpet square.
b. Scrub cleanser for 30 sec. with one paper towel.
c. Label square with name of cleanser used.
d. Repeat steps A-C on all remaining carpet squares in this group.
e. Repeat steps A-D with each of the following cleaners (OC & WOD).
6. Determine whiteness.
a. Take all carpet squares to local laboratory.
b. Use colorimeter to determine “L” value for each square.
c. Record data.
d. Average within each group.
The original purpose of this experiment was to find out which brand of carpet cleaner removed stain most efficiently.
The results of the experiment were that Oxi Clean (67.046 whiteness) worked the best when removing a stain, opposed to Woolite Oxy Deep (67.02 whiteness) and Resolve (66.476 whiteness).
CONCLUSION
My
hypothesis was that Resolve brand would remove the stain best.
The
results indicate that this hypothesis should be rejected, because the Oxi Clean
brand removed the stain most efficiently, although the differences were very
small.
After
thinking about the results of this experiment, I wonder what the results would
be like if I conducted an experiment such as Steam Cleaners vs. Spray-on or
Carpet Materials vs. Stain Resistance.
If I
were to conduct this project again I would use more carpet squares in each
group and test a larger variety of cleaners. I would also use a more difficult
stain to remove like red wine, chocolate sauce, or motor oil. I would steam
clean the carpet before staining, to remove factory protectants. I would have
added one more control, too, and stain it, to compare the stain before to the
stain after treatment.

Carpet steam cleaning, also known as hot water extraction, is the preferred method for deep cleaning carpets because of its ability to remove stubborn stains and embedded dirt. Steam cleaning machines blast your carpet with hot water and then use powerful suction to remove loosened dirt and excess moisture, leaving your carpet feeling and smelling fresh and clean. Here are some tips if you are considering deep steam cleaning your carpets. While carpet steam cleaning is recommended by most carpet manufacturers, you should still consult with your carpet’s manufacturer to ensure that steam cleaning is safe and will not adversely affect your carpet’s fibers, dyes, and construction. To achieve the best results, hire a professional to steam clean your carpets. A reputable carpet cleaning business can offer a guarantee that your carpets will be cleaned safely and effectively without any damage. Look for a company that is certified and uses Seal of Approval products and equipment, which have been tested to ensure high quality treatment. If you have pet urine stains, it is important to thoroughly clean and remove the stains before proceeding with carpet steam cleaning. Steam cleaning is not recommended for pet stains, since hot water can cause the crystals in your pet’s urine to bond to your carpet’s fibers, creating permanent stains and odors.
