Natural cleaning products will be less effective at killing bacteria and removing tough stains compared to chemical cleaners, but they will be gentler on surfaces and have fewer long-term effects on the environment.

Chemical:

We are using Tide to clean stains for the chemical part of the project. Some of the chemicals in Tide are: surfactant, process aid, enzyme, preservative, stabilizer, aesthetics, bittering agents, sodium salt, solvent, brightener, wash aid, scent, polymer, film, colour safe bleach, cleaning aid. Some of those allow ingrdients to combine, reduce foam, whithens and brightens clothes, helps clean in hard water, helps with whitness, helps formula thickness, helps balance pH, stabilizes enzymes, water softner, cleans protein based stains, keeps ingredients in chambers, cleans pectin stains, helps stabilize perfume, cleans vegetble stains, cleans grease stains, provides freshness, capture soils, gives pleasing colour, cleans clothing fibers, thickness regulator, stabilizes formula, provides softhening benefits, cleans starch based stains and provides opacity to formula.

NATURAL:

In our experiment, we are using natural cleaners like vinegar and baking soda. Vinegar works because it’s acidic, which helps break down grease, dirt, and mineral deposits. It can kill some types of bacteria, but it’s not as strong as chemical cleaners. It's great for cleaning everyday messes on surfaces like kitchen and cleaning cloths, though it can damage sensitive surfaces like granite if we used too much.

Baking soda is a mild scrubber that helps clean by gently scrubbing away dirt and stains without scratching surfaces. It also absorbs odors, which is why it’s often used in places like refrigerators and carpets. While it doesn’t kill bacteria, it helps lift grime and stains. When combined with vinegar, it creates a fizzy reaction that helps remove dirt.

Together, vinegar and baking soda are safe, natural, and non-toxic, making them good for regular cleaning and the environment. However, they might not be as powerful as chemical cleaners for tough stains or heavy-duty disinfection.

Chemical Cleaners: The Science Behind Their Effectiveness

Chemical cleaners, such as Tide, are specifically designed with a blend of ingredients to effectively remove stains and disinfect surfaces. These products contain surfactants, which reduce surface tension between dirt and fabric, allowing the cleaner to lift and remove grime more easily. Enzymes are another essential component in chemical cleaners, as they break down organic materials like food, sweat, and bodily fluids. Additionally, bleach and other oxidizing agents in chemical cleaners help kill bacteria and viruses, providing thorough disinfection. According to the American Cleaning Institute, the combination of surfactants, enzymes, and bleach in products like Tide makes them highly effective at tackling tough stains and bacteria. Many chemical cleaners also contain phosphates, which soften water and improve performance in hard water conditions. However, concerns have been raised about the long-term health effects of synthetic fragrances, preservatives, and bleach found in chemical cleaners. Longer exposure to some ingredients has been linked to skin irritation, respiratory issues, and environmental damage.

Natural Cleaners: Effectiveness and Limitations

Natural cleaners, such as vinegar and baking soda, are favored by those looking for safer and eco-friendly alternatives to chemical products. Vinegar, being mildly acidic, works effectively to break down grease, grime, and mineral deposits while also serving as a natural deodorizer. Baking soda acts as a mild sturdy cleaner, scrubbing away dirt without scratching surfaces. When combined, vinegar and baking soda create a fizzy reaction that helps lift dirt. Despite their effectiveness in everyday cleaning, natural cleaners are less powerful when it comes to removing tough stains or disinfecting surfaces. Research published in the Journal of Environmental Health shows that while vinegar and baking soda have some antimicrobial properties, they are not as effective as chemical disinfectants in killing bacteria and viruses. Vinegar can kill bacteria like E. coli and Salmonella, but it is not effective against viruses such as the flu. Baking soda, although helpful in scrubbing dirt, does not have strong disinfecting properties. Nonetheless, natural cleaners are valued for being non-toxic, biodegradable, and safe for cleaners with children and pets.

Environmental Impact of Chemical vs. Natural Cleaners

The environmental impact of cleaning products is a growing concern for consumers. Chemical cleaners, such as Tide, often contain ingredients like phthalates and formaldehyde, which can contribute to indoor air pollution and harm both human health and the environment. The release of volatile organic compounds (VOCs) from these chemicals can cause respiratory problems and contribute to smoke. Moreover, many of these substances can pollute water sources, harming aquatic ecosystems. In contrast, natural cleaners like vinegar and baking soda are generally more eco-friendly. Derived from plant-based sources, these ingredients are biodegradable and break down naturally, leaving fewer toxic residues. According to the Environmental Working Group (EWG), natural cleaners contribute significantly less to air and water pollution than their chemical counterparts. However, it is important to recognize that some natural cleaners, especially those containing essential oils or additives, can still have an environmental impact. Overuse of certain essential oils, for example, can lead to resource depletion. While natural cleaners are generally more environmentally friendly, consumers should still be mindful of the complete product composition.

Comparison of Cleaning Effectiveness

When comparing the cleaning power of natural and chemical cleaners, several studies highlight key differences, especially when it comes to tough stains. Chemical cleaners like Tide excel at removing stubborn stains, such as oil, ink, and blood, due to their specialized chemical formulations. Surfactants, enzymes, and bleach work together to break down complex stains and effectively lift them from fabrics and surfaces. However, for lighter stains or regular cleaning tasks, natural cleaners can be just as effective. Vinegar’s acidic properties are particularly useful for removing grease and mineral deposits, and when paired with baking soda, it forms a strong cleaning combination. While natural cleaners work well for routine cleaning and mild stains, they may not provide the same level of stain removal and disinfection as chemical cleaners. Research from the Journal of Food Control (2017) suggests that natural cleaners are less effective against grease-based stains and tough marks like red wine or ink. Natural cleaners rely more on physical scrubbing and mild chemical reactions, while chemical cleaners contain stronger agents designed to break down these types of stains.

Bacterial Disinfection: Natural vs. Chemical Cleaners

Disinfection is a key factor in cleaning, especially in areas like kitchens and bathrooms where germs are common. While vinegar and baking soda do have some antibacterial properties, they are not as effective as chemical disinfectants. According to the EPA, products like bleach and disinfectants in chemical cleaners are specifically designed to kill a broad range of bacteria and viruses, including those responsible for illnesses like the flu, colds, and foodborne diseases. Natural cleaners, although effective for everyday cleaning and minor bacteria control, are less reliable in ensuring harmful pathogens are eliminated. For instance, vinegar is effective against bacteria like E. coli, but it does not offer comprehensive protection against viruses. Therefore, for situations requiring strong bacterial disinfection, chemical cleaners are the more dependable choice. On the other hand, natural cleaners are ideal for mild disinfecting in less germ-prone areas, making them a great choice for households that prioritize safety and sustainability.

Conclusion: A Balanced Perspective

In conclusion, both natural and chemical cleaners have their strengths and limitations, and the choice between them depends on the cleaning needs and priorities of the user. Chemical cleaners like Tide are highly effective at removing tough stains and eliminating bacteria, making them ideal for deep-cleaning tasks. However, their environmental impact and potential health risks should be considered, especially with frequent use or in poorly ventilated spaces. Natural cleaners like vinegar and baking soda offer a safer, eco-friendly option for regular cleaning and mild stain removal. While they may not match the cleaning power of chemical cleaners in certain situations, they provide a non-toxic solution that is safe around children, pets, and sensitive surfaces. For everyday cleaning, natural cleaners are an excellent choice, but for heavy-duty stains or bacterial disinfection, chemical cleaners may be more suitable.

Future Research Directions

Further research is needed to examine the long-term health effects of exposure to chemical cleaners, particularly regarding respiratory health and skin sensitivity. It would also be valuable to explore the effectiveness of newer, eco-friendly cleaning products that combine the power of chemicals with the sustainability of natural ingredients. Investigating biodegradable ingredients and their true environmental impact could help refine the development of greener cleaning products, ensuring that they remain both effective and environmentally safe. Additionally, studying the effects of various cleaning products on different surfaces—particularly delicate ones like granite or hardwood—could provide insights on preserving the longevity of home surfaces while maintaining cleanliness.

For our experiment comparing the effectiveness of natural vs. chemical cleaning products, the independent variables include the type of cleaner, which will be vinegar, baking soda, chemical cleaner, and eco-friendly cleaner. The surfaces being cleaned will be polyester, polyamide, and cotton. Additionally, tea and oil will be used as stains for testing. The cleaners will be left on the surfaces for 24 hours, and the amount of cleaner used will be one-fourth of a cup. To clean the surfaces, kitchen cloths and cleaning cloths will be used, ensuring the same material is applied for each cleaner. The dependent variables include the effectiveness of stain removal, which will be observed and rated on a scale based on how much of the tea oil stain is removed. Since Petri dishes are not being used, bacterial growth will not be tested. Instead, we will be the judge by using our eyes. Controlled variables will include the surface material, amount of cleaner used, the cleaning method with the same cloth, and the 24-hour duration of cleaning. By keeping these factors consistent, the experiment will allow for a clear comparison of how well each cleaner performs in removing stains and cleaning the surfaces.

1. Preparation:
   a. Clean the surfaces of materials (e.g., wood, granite) with a swab and ensure that each has a known amount of bacteria or dirt on them.
   b. Prepare stains on fabrics or surfaces using oil, ink, or red wine.
2. Treatment:
   a. Use one natural cleaner (e.g., vinegar) on a set of test surfaces and one chemical cleaner (e.g., bleach) on another set, following the instructions for each.
   b. Allow each cleaner to sit for a specified amount of time, ensuring consistency in duration.
3. Stain Removal Test:
   a. Compare the effectiveness of each cleaner at removing stains after applying and letting sit for an appropriate time. Use a cloth or sponge for application, and document the appearance of the stain before and after cleaning.
4. Green Cleaner Comparison (Optional):
   a. Test newer "green" eco-friendly cleaners and compare their effectiveness against traditional chemical cleaners and natural cleaners.
5. Data Analysis:
   a. Analyze the effectiveness of the different cleaners in terms of bacteria growth, stain removal, and surface preservation.
   b. Compare natural, chemical, and green cleaners based on cleaning performance, environmental impact, and surface effects.

Chemical:

Microfibre cloth tea stain:

Before I washed the cloth the cloth was tinted yellow. Most of the tea stain is gone after the first rinse and wash. I did the process again so the odour was gone.

Microfibre cloth oil stain:

Before I washed the cloth you couldn't really see the stain, it was really faint. The oil stain was gone after one rinse and scrub. I repeated the process again so the odor was gone.

Cotton cloth tea stain:

 Before I washed the cloth the cloth had a light brown stain. After I washed it once the stain didn't really  go away the stain was lighter than before. I did the process again and the stain was lighter than the previous time I washed it. 

Cotton cloth oil stain:

Before I washed the cloth the stain was really, really faint you couldn't see anything. After the first wash some of the odour was gone but not fully. I did the process again to fully get rid of the oil odour.

Observation:
In this experiment, we observed how different cleaners worked on stains of black tea and olive oil on various fabrics. We used vinegar and baking soda as natural cleaners, along with a chemical cleaner, to test their effectiveness. After applying the cleaners and allowing them to sit for 24 hours, we found that chemical cleaners were more effective at removing stains, particularly black tea. For example, the black tea stain on polyester and polyamide fabrics was almost completely gone with the chemical cleaner, while vinegar and baking soda left faint traces of the stain. On the olive oil stains, the chemical cleaner worked better, but it still left some marks, especially on cotton. Vinegar and baking soda struggled more with the olive oil stain, leaving more noticeable traces. Overall, the natural cleaners did clean the stains but weren’t as strong at removing tougher stains like oil or tea.

The Tide original product that we used removed the stians for the most part. For the cotton cloth the tea stain didn't really go away , but for the microfibre cloth the tea stin was cleaned. As for both of the oil stains both were gone.

The Tide original cleaning product worked well.

Have you ever spilled something and forgotten about it, only to discover a stubborn stain the next day? The big question then becomes: what’s the best way to tackle that stain? Should you rely on chemical cleaners, or are natural alternatives a better choice?

Our project aims to answer this question by comparing the effectiveness, eco-friendliness, and long-term impact of different cleaning products. We’ll dive into a hands-on experiment to determine which brands deliver the best results without compromising your health or the environment. Say goodbye to stains—and hello to a cleaner, greener home!

The only source of error one the chemical side of the expiement is that the cotton cloth's tea stain didn't really go.
