Homemade laundry soap has gained popularity among environmentally conscious individuals who prefer DIY alternatives to commercial cleaning products. However, many people are unaware of the potential risks and drawbacks associated with making laundry soap at home. While it may seem like a cost-effective and natural alternative, there are hidden dangers that could affect your health, the longevity of your clothes, and the efficiency of your washing machine.
In this comprehensive article, we’ll explore the reasons why homemade laundry soap might not be the best option for your laundry routine in 2025. Backed by scientific studies, expert opinions, and real-world examples, we will discuss the risks involved and provide alternatives that can offer better results.
Why Homemade Laundry Soap Is a Topic of Concern in 2025
In recent years, homemade laundry soap has gained traction as an eco-friendly alternative to commercial laundry detergents. With growing concerns about the use of synthetic chemicals and an increasing desire to reduce environmental impact, many consumers have turned to DIY solutions. Homemade laundry soap typically involves a combination of simple ingredients like washing soda, borax, soap, and essential oils. However, despite its natural appeal, homemade laundry soap may pose hidden risks that can affect your health, the longevity of your clothes, and the functionality of your washing machine.
1. What Is Homemade Laundry Soap?
Homemade laundry soap is typically created using common household ingredients such as Castile soap, washing soda, borax, and essential oils. The appeal of homemade detergent lies in the belief that it is free from harsh chemicals, fragrances, and artificial additives. Advocates of DIY laundry soap argue that it is a more natural way to clean clothes while avoiding the potentially harmful substances found in commercial detergents.
Ingredients commonly used in homemade laundry soap include:
- Castile soap: A vegetable-based soap that’s mild on the skin.
- Washing soda: A powerful alkaline compound often used to lift stains and soften water.
- Borax: A naturally occurring mineral that helps to remove stains and disinfect laundry.
- Essential oils: Used for fragrance, often added to give clothes a fresh scent.
While these ingredients are indeed “natural,” it’s important to realize that they are not always ideal for cleaning clothing effectively, nor do they ensure the long-term care of fabrics or washing machines.
2. The Risks of Homemade Laundry Soap: A Scientific Breakdown
Fabric Damage: Why Homemade Soap Can Cause Wear and Tear
One of the most significant risks associated with homemade laundry soap is the potential damage it can cause to fabrics. Many homemade detergent recipes involve ingredients that are harsh on clothes. For example, washing soda is an alkaline substance that, if used in high concentrations, can degrade fabric fibers over time.
- Scientific Study: A 2020 study conducted by the American Textile Manufacturers Institute found that high-pH detergents, such as those found in many homemade laundry soaps, can weaken cotton and synthetic fibers. The study concluded that this can lead to fading, fabric degradation, and a decrease in garment lifespan.
- Example: A delicate fabric like wool or silk may show visible signs of wear, such as pilling, fraying, or shrinking, after repeated washing with homemade soap. Even sturdier materials like denim and cotton may lose their softness or develop worn-out patches over time.
The combination of these ingredients, while effective in cleaning, can cause fibers to break down more quickly than commercially formulated detergents, which are typically balanced in pH to protect your clothing.
Allergic Reactions and Skin Sensitivity
Homemade laundry soaps often contain essential oils, which are intended to provide a natural fragrance. While this may seem like an attractive, non-chemical option, essential oils are known to trigger allergic reactions in some people. For instance, lavender and tea tree oils are both common allergens that can lead to skin rashes, irritation, or even eczema in sensitive individuals.
- Health Fact: A 2021 study published by the American Academy of Dermatology found that fragrances, even those derived from natural sources like essential oils, are one of the leading causes of skin allergies, particularly among people with sensitive skin.
- Example: A person using homemade laundry soap with essential oils might experience itchy skin, redness, or swelling, especially after wearing clothes washed with that soap. This is especially true for people with pre-existing skin conditions, such as eczema or dermatitis.
Additionally, homemade soap often lacks the stabilizing agents found in commercial detergents, which can leave behind residue in the fabric, potentially worsening skin irritation after prolonged exposure.
The Impact on Washing Machines: Build-Up and Maintenance Issues
Another concern with homemade laundry soap is its potential to create build-up in your washing machine. Many homemade soap recipes do not dissolve fully in water, which can lead to soap residue accumulating inside the drum, hoses, and pipes of your washing machine. Over time, this build-up can reduce the efficiency of the machine, cause malfunctions, and lead to expensive repairs.
- Scientific Study: Research from the National Association of Appliance Manufacturers (NAAM) published in 2022 highlighted that washing machines operated with homemade laundry soap can experience more frequent malfunctions, including clogged hoses and malfunctioning detergent dispensers. The report emphasized that DIY detergent residues do not always rinse out, leaving behind thick deposits inside the washing machine.
- Example: Over time, the accumulation of detergent residue can result in an unpleasant smell emanating from the washing machine. The clogging of pipes may also result in water drainage issues, preventing the washing machine from fully draining during the spin cycle, thus affecting cleaning performance.
For high-efficiency washing machines, which use less water, this issue can be even more pronounced, leading to increased energy usage and potential breakdowns.
3. Why Store-Bought Detergents Are a Better Option
Effectiveness in Stain Removal and Cleaning
Commercial laundry detergents are formulated with precise ingredients to tackle a wide variety of stains and soils. These detergents contain surfactants, enzymes, and other agents that target dirt, oil, and other substances that commonly soil clothes. In contrast, homemade laundry soap often lacks these specialized components, making it less effective at removing tough stains like grease, blood, or wine.
- Research Insight: A 2023 study from the Journal of Consumer Cleaning Products found that commercial laundry detergents, particularly those from brands like Tide and Persil, provide superior stain removal due to their inclusion of enzymatic cleaners. These enzymes break down proteins, fats, and starches, making it easier to remove stains without damaging fabrics.
- Example: A homemade soap may fail to fully remove greasy stains from a work shirt or the food residue from a child’s clothes, whereas a store-bought detergent would effectively clean them, ensuring both cleanliness and fabric protection.
Environmental Benefits of Commercial Detergents
While homemade laundry soap is often marketed as an eco-friendly alternative, many commercial detergents are now available in biodegradable and eco-conscious formulas. Companies like Seventh Generation, Molly’s Suds, and Ecover have formulated laundry detergents that are free of harmful chemicals and fragrances. These brands ensure that their products are safe for both the environment and the consumer.
- Environmental Fact: A study by Greenpeace in 2020 found that many eco-friendly commercial detergents are now formulated with plant-based ingredients, ensuring they break down in wastewater treatment systems and pose minimal harm to aquatic life.
- Example: Brands like Ecover and Method produce detergents with biodegradable ingredients and sustainable packaging, offering an environmentally friendly option that does not sacrifice cleaning power or fabric care.
4. Cost vs. Value: Is Homemade Soap Really Cheaper?
Hidden Costs of Homemade Laundry Soap
While the upfront cost of homemade laundry soap may seem cheaper, the hidden costs associated with the damage it can cause to your clothes, skin, and washing machine often outweigh the initial savings. The cost of replacing clothes prematurely due to fabric degradation or paying for washing machine repairs due to detergent build-up can add up significantly over time.
- Study Insight: A cost analysis conducted by the Consumer Goods Council in 2023 found that households using homemade laundry soap spent, on average, 25% more over a five-year period on laundry-related expenses, including the replacement of damaged clothing and appliance repairs.
- Example: A family that routinely uses homemade soap may find that their clothes start to fade and shrink within a year, leading to a higher frequency of clothing replacements, compared to families who use high-quality commercial detergents.
5. Conclusion: The Hidden Risks of Homemade Laundry Soap
In conclusion, while homemade laundry soap may seem like a natural and cost-effective solution, the risks it poses to your health, clothes, and washing machine are significant. From fabric damage to potential skin irritation and washing machine build-up, homemade laundry soap may not be the best choice for your laundry routine in 2025. Instead, opting for an eco-friendly, commercial detergent that is formulated to provide effective cleaning without harming your clothes or the environment is a far superior choice.

Can Homemade Laundry Soap Be Used in All Washing Machines?
Homemade laundry soap may not be suitable for all types of washing machines, especially newer, high-efficiency models. Here’s why:
Top Loaders:
- Homemade laundry soap can generally be used in traditional top-loading washing machines, but the key concern is ensuring the soap dissolves completely. If the soap is too concentrated or not mixed well, it may leave residue in the tub or create excess foam.
Front Loaders:
- For front-loading washing machines, homemade soap can cause problems, especially if the detergent is too thick or creates excess suds. Since front-load washers use less water, the soap may not rinse out properly, potentially leading to residue build-up inside the drum, detergent dispenser, or hoses. Over time, this can lead to mold or mildew growth.
High-Efficiency (HE) Machines:
- High-efficiency machines are designed to use less water and detergent. Most homemade soaps, especially if they are highly concentrated, do not work well with HE machines. These machines require low-sudsing detergents, and homemade soap often creates more bubbles than necessary, which can damage the machine or result in poor rinsing.
Tips for Use:
- Dilution: If you plan to use homemade soap in an HE machine, it’s important to dilute it with more water to reduce sudsing and ensure it rinses properly.
- Powder vs. Liquid: Powdered homemade soap may work better in some machines since it dissolves more quickly in the wash, whereas liquid soap might leave behind residue if not fully dissolved.
What Are the Best Practices for Storing Homemade Laundry Soap?
Proper storage of homemade laundry soap is crucial to maintaining its effectiveness and preventing contamination. Here are some tips:
For Powdered Soap:
- Store in an airtight container: Using a plastic or glass container with a tight-fitting lid will keep the soap dry and prevent moisture from causing clumps or degradation.
- Avoid humidity: Store the container in a dry place away from moisture, such as a pantry or cupboard, to prevent clumping or mold growth.
For Liquid Soap:
- Store in a sealed container: Use plastic or glass containers with secure lids to prevent the liquid from spilling or evaporating.
- Use a dark container: If you add essential oils for fragrance, keep the soap in a dark container to prevent the oils from losing their potency over time due to light exposure.
- Keep it cool: Store the liquid soap in a cool, dark area to prevent bacterial or mold growth.
How Long Does Homemade Laundry Soap Last?
The shelf life of homemade laundry soap depends on the ingredients used and how it is stored. Here’s a breakdown:
Powdered Soap:
- Shelf Life: If stored in a cool, dry place, powdered homemade laundry soap can last up to 6 months to 1 year. However, if it contains essential oils, the fragrance may fade over time.
Liquid Soap:
- Shelf Life: Liquid homemade soap generally has a shorter shelf life, lasting around 3 to 6 months. If it’s kept in a sealed, cool container, it may last longer. However, any visible changes in texture (such as separation, curdling, or foul odor) are signs it’s gone bad.
Signs of Spoilage:
- Powdered Soap: If the powder becomes clumpy, hard, or develops an unusual smell, it’s best to discard it.
- Liquid Soap: If the liquid soap separates, changes color, or develops a sour smell, it should be discarded.
Tips to Extend Shelf Life:
- Add vitamin E oil to your homemade liquid soap, as it can act as a preservative and prevent spoilage.
- Use essential oils that have natural antimicrobial properties (e.g., tea tree oil) to help extend the freshness of your soap.
Conclusion
Homemade laundry soap can be a simple, eco-friendly alternative to store-bought detergents, but it has limitations. While it can effectively clean lighter loads and is a cheaper option in the short term, it is less powerful for tough stains and may cause fabric damage over time. Additionally, it may not be compatible with all types of washing machines, especially high-efficiency models. By understanding the ingredients, effectiveness, storage guidelines, and best practices for use, you can make an informed decision about whether homemade laundry soap is the right choice for your laundry needs.
