Stain Removers Explained

Spot remover sprays are celebrated allies in the battle against stubborn stains on clothing, upholstery, carpets, and other textiles. By combining carefully selected chemicals with targeted delivery systems, these sprays penetrate, break down, and lift away unwanted blemishes.

Many stain removers utilize a variety of chemical techniques to eliminate or conceal stains. There isn’t just one approach to stain removal; instead, there are multiple reactions that help achieve bright whites or eliminate stains from grass or blood.

Typically, stain removers consist of solvents, surfactants, and enzymes.

How Do Stain Removers Work?

Dissolve the Stain

Stain removers are specially formulated substances that contain solvents. A solvent is defined as any fluid that has the ability to dissolve another chemical, resulting in a solution. For instance, water is recognized as an effective solvent when it comes to dissolving substances like salt and sugar due to its polar molecular structure.

Conversely, water is not effective for dissolving nonpolar substances such as oils or butter, which require a different type of solvent. To tackle various types of stains, stain removers commonly include volatile components like alcohol, which serves as a solvent capable of breaking down both water-based stains, such as juice or coffee, and oil-based stains, like grease or salad dressing. Additionally, hydrocarbon solvents, which include substances such as gasoline and certain cleaning agents, are effective in dissolving tough stains that resist water-based solutions.

The fundamental principle guiding the choice of solvent is encapsulated in the adage “like dissolves like.” This principle suggests that for optimal stain removal, one should use a solvent that is chemically similar to the stain being treated.

Therefore, if you find yourself dealing with a water-based stain, you would benefit from employing a water-based solvent such as club soda, which is carbonated water that can help lift stains, or soapy water, which utilizes a surfactant to enhance cleaning efficacy. On the other hand, when confronting an oily stain, solvents like rubbing alcohol or gasoline can be effective, as they are better suited to dissolve non-polar oils.

Emulsify the Stain

To effectively lift stains, stain removers also comprise emulsifiers or surfactants. Emulsifiers function by coating the stain, thus allowing for easier removal by loosening its grip on the surface material. Surfactants enhance the wettability of various materials, which increases the likelihood that the stain remover will contact and successfully remove the stain.

Common examples of surfactants include traditional soap and sulfonates. These substances possess a unique molecular structure characterized by a dual nature, enabling them to target both aqueous (water-based) and oily stains. Each surfactant molecule comprises a polar “head” that is soluble in water and a hydrocarbon “tail” that is attracted to grease and oil.

When a surfactant is applied to a stain, the hydrocarbon tail binds to the oily portion of the stain while the hydrophilic head associates with water. This interaction allows multiple surfactant molecules to cluster around the stain, forming structures known as micelles, which encapsulate the stain and facilitate its rinsing away with water.

Digest the Stain

Another potent method employed in stain removers is the use of enzymes or other proteins specifically engineered to dismantle stain molecules at a molecular level. Enzymes, which are biological catalysts, are capable of breaking down complex proteins and fats present in various stains, much like they play a role in digesting food within our bodies.

Enzyme-based stain removers have proven to be particularly effective when it comes to organic stains, such as blood or chocolate, as they work to break down the very components that constitute these stains.

To further aid in stain removal, chemical oxidizers can also be employed. These substances function by breaking apart long, colored molecules typically found in stains, making them easier to remove and, in certain situations, rendering them colorless. Common oxidizers used in stain removal include hydrogen peroxide, chlorine bleach, and borax, all of which can significantly enhance the stain removal process by targeting the color agents present in stains.

Hide the Stain

A strategic approach employed by many stain removers involves the inclusion of whiteners. While these chemicals may not necessarily contribute to the cleaning efficacy of the product, they play a crucial role in making stains less visible.

Bleaching agents work by chemically oxidizing the colored components of a stain, effectively lightening its appearance and making it less pronounced. Other forms of whiteners operate by reflecting light, thereby diffusing the visibility of the stain or camouflaging it against the surface on which it resides.

In practice, most commercial stain removal products, as well as homemade cleaning solutions, do not rely solely on a single method to combat stains. Instead, they utilize a combination of techniques to effectively tackle the issue.

For example, applying a diluted solution of chlorine bleach to a stain not only helps to break down the chemical bonds of the stain molecules but also removes the unwanted color from the fabric or surface.

Meanwhile, simple solutions like soapy water possess the ability to dissolve a wide range of stains, whether they are oily or aqueous, and coat the stain, thereby making the rinsing process much smoother and more efficient.

Common Ingredients in Most Stain Removers

Spot remover sprays are formulated to address a wide array of stains: grease, wine, coffee, grass, blood, ink, and more. To do so, they rely on several functional classes of ingredients.

Each is included for a specific purpose, whether it’s to break chemical bonds in the stain, loosen particles, or ensure the formula can be sprayed evenly. The following are the most commonly utilized components:

Surfactants (Detergents)
Surfactants are used to reduce surface tension, allowing water and cleaning agents to penetrate fabric fibers. They function by surrounding oil or grease particles, making them dispersible in water so that they can be rinsed away. Nonionic and anionic surfactants are most commonly selected for household stain removers.

Enzymes
Biological catalysts such as proteases, lipases, and amylases are often included to target protein-based stains (blood, egg), lipid-based stains (butter, oil), and carbohydrate-based stains (sauce, starch), respectively.

Enzymes operate by cleaving large starch molecules into smaller, water-soluble fragments.

Solvents
These solvents work by breaking down the chemical bonds within the stain, allowing it to be lifted from the surface more easily. When using organic solvents, it is important to test the solution on a small, inconspicuous area first to ensure it does not damage the material.

Additionally, proper ventilation and protective gear, such as gloves, should be used to minimize exposure to potentially harmful fumes.

Oxidizing Agents
Agents such as hydrogen peroxide, sodium percarbonate, or sodium perborate generate reactive oxygen species that attack chromophores—the parts of molecules responsible for color.

Oxidation breaks these chromophores, rendering stains colorless and more easily washed away.

Builders and pH Adjusters
These compounds not only enhance the stability of the detergent formulation but also prevent the redeposition of soils onto fabrics during the washing process.

By reducing water hardness, they allow surfactants to work more effectively, ensuring a thorough and efficient clean.

Solubilizers and Stabilizers  

These ensure that active ingredients remain dissolved (or evenly dispersed) within the spray formulation over time, preventing separation or precipitation. They also help maintain the product’s consistency, ensuring uniform application and maximizing effectiveness.

By enhancing the stability of the formulation, solubilizers and stabilizers extend the product’s shelf life and improve overall performance under varying storage conditions.

Fragrances and Preservatives
Added for consumer appeal and shelf-life stability, respectively, these are secondary but commonly found components. Fragrances enhance the sensory experience of a product, making it more appealing to users, while preservatives play a crucial role in preventing the growth of bacteria, mold, and yeast, thereby extending the product’s usability and ensuring safety.

Despite their benefits, these components can sometimes cause sensitivities or allergic reactions in certain individuals, leading to a growing demand for fragrance-free and preservative-free alternatives in the market.

Harmful Chemicals in Stain Removers & How We Can Avoid Them

While many commercial spot remover sprays are highly effective, certain chemicals they contain can be harmful to human health or the environment. By becoming aware of these substances, consumers can make safer choices or avoid them altogether.

Phosphates

Why They’re Used: Phosphates act as water softeners by binding calcium and magnesium, enhancing cleaning power.

Concerns: When released into waterways, phosphates can cause algal blooms, leading to oxygen depletion in aquatic ecosystems.

Look for “phosphate-free” labeled products or choose eco-certified brands that use alternative builders like sodium citrate.

Chlorinated Solvents (e.g., Perchloroethylene)

Why They’re Used: Extremely effective degreasers for tough oil and wax stains.

Concerns: Volatile organic compounds (VOCs) can be inhaled, causing respiratory irritation or central nervous system effects; they’re also persistent environmental pollutants.

Opt for water-based sprays or those using low-toxicity bio-solvents.

Glycol Ethers

Why They’re Used: Powerful solvents for inks, dyes, and oily stains.

Concerns: Some glycol ethers (e.g., 2-butoxyethanol) have been linked to reproductive toxicity and blood disorders when inhaled or absorbed through the skin.

Read ingredient lists carefully; choose products labeled “solvent-free” or “low-VOC.”

Formaldehyde Donors (e.g., Methylene glycol)

Why They’re Used: Preservatives to prevent microbial growth in liquid formulations.

Concerns: Formaldehyde is a known carcinogen and respiratory irritant. Even donors that slowly release formaldehyde can pose risks to sensitive individuals.

Seek “preservative-free” or “paraben-free” formulas; ensure adequate ventilation during use.

Synthetic Fragrances

Why They’re Used: Mask the chemical odor of active ingredients, imparting a fresh scent.

Concerns: Fragrance mixtures often contain phthalates or other hormone-disrupting chemicals; they can trigger asthma and allergies.

Select unscented or naturally scented products (e.g., essential oils).

Quaternary Ammonium Compounds (Quats)

Why They’re Used: Used as disinfectants or fabric softeners with stain-lifting properties.

Concerns: Some quats have been associated with skin irritation, respiratory issues, and environmental persistence.

If disinfecting is unnecessary, choose quat-free stain removers.

Tangie stain remover stick full ingredients list: Coconut Oil, Water, saponified Sodium Hydroxide, Lemon Juice, Borax.  There are no synthetic fragrances, dyes, or colorants in our stain remover.

The following ingredients are typically found in household stain removers. We choose NOT to use them and here is why… With Tangie products, we prioritize your health and the environment. Here’s a closer look at some common harmful ingredients found in cleaning products that can negatively impact both human health and aquatic life.

1. Acrylic Acid

Acrylic acid is highly toxic to aquatic organisms. If it poses a threat to marine life, it’s an ingredient we refuse to let enter our waterways. Notably, products like Lysol Disinfectant Spray for Baby’s Room contain this harmful acid and have received an F rating from the Environmental Working Group (EWG). At Tangie Co, we believe in safer alternatives for our homes and the planet.

2. Synthetic Fragrances

Synthetic fragrances are often exempt from labeling requirements and are treated as “trade secrets.” This means consumers cannot identify the individual components, which may include phthalates. Exposure to these chemicals has been linked to various health issues, such as:

• Aggravation of asthma
• Headaches
• Allergic reactions
• Potential long-term central nervous system disorders

3. Chlorine Bleach

Chlorine bleach can be dangerous, especially with prolonged exposure to low levels of chlorine gas. Health risks include:

• Permanent lung diseases, such as bronchitis
• Shortness of breath

4. Ammonia

Ammonia is a corrosive substance, and its health effects can vary based on exposure routes, doses, and durations. High concentrations can cause:

• Immediate burning of the eyes, nose, throat, and respiratory tract
• Severe consequences, including blindness and lung damage

5. 1,4-Dioxane

1,4-Dioxane is a known carcinogen often associated with Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES). Its presence is due to the manufacturing process of these surfactants, making it crucial to avoid products containing them.

6. Propylene Glycol

Commonly used as a solvent, propylene glycol can be a primary skin irritant. Concerns also include potential links to liver abnormalities and kidney damage.

7. Phosphates

Phosphates act like fertilizers in our water systems, leading to excessive algae growth. This depletes oxygen levels necessary for healthy fish and aquatic life, disrupting entire ecosystems.

PS – We cannot discuss ingredients without bring up sodium borate. Sodium borate goes by many names on ingredient labels, including borax. We use borax in this stain remover bar.

At Tangie, we believe and trust in the value of the safety database assembled by the Environmental Working Group. So, we understand borax gets a terrible rating on their website. However, it’s important to note that the ingredient is safe when used correctly.

Borax originates in a powder form. When inhaled, the powder can irritate the eyes and lungs. It can also be harmful via long-term skin exposure. Personal care companies have been known to add it to their products, which can be harmful with long-term exposure to direct skin contact.

If you are concerned about the borax in this stain remover bar, you can wear gloves or use the paper wrapper on the stain remover bar as the barrier between the bar and your skin. However, if you use the product as recommended and wash it off completely after applying it to your stains, you should not experience any trouble unless you also have skin sensitivities to borax or the other ingredients in the bar.

Learn more about borax’s use as a stain and scent remover in this article. PPS – We want you to be completely confident in the ingredients you will encounter using Tangie products.
