It is also important to understand the detergent and stain remover ingredients. Only in this way can they make correct decisions during washing and stain removal. This can effectively reduce wash issues.<\/p>\n<h2><strong>Common Ingredients<\/strong><\/h2>\n<ul>\n<li>Surfactant<\/li>\n<\/ul>\n<p>Whether powder or liquid detergents, the core effective ingredient is surfactant. It is a charged molecule. One side is hydrophilic, while the other is hydrophobic. The dual nature helps effectively remove grease and soil from textiles. Soil finally suspends in water. So detergents often generate foam.<\/p>\n<p>Metal salts (calcium and magnesium) in hard water reduce surfactant efficiency and form soap scum. Modern detergents solve this issue by adding phosphates, water softeners, and chelating agents. However, phosphates trigger an algal bloom. Phosphate-based detergents have been prohibited in many areas. Therefore, water softeners have become popular in the <a href=\"https:\/\/kingstarlaundry.com\/ar\"><strong><u><b>commercial laundry industry<\/b><\/u><\/strong><\/a>.<\/p>\n<ul>\n<li>Optical brightener<\/li>\n<\/ul>\n<p>Some detergents contain optical brighteners. They absorb UV and emit blue light. This enables white garments to be whiter and colored garments to be lighter. Fragrance is often used to add fresh smells. But it is not required for cleaning.<\/p>\n<h2><strong>Main Ingredients of <\/strong><strong>P<\/strong><strong>owder<\/strong><strong>\/Liquid D<\/strong><strong>etergent<\/strong><strong>s<\/strong><\/h2>\n<ul>\n<li>Powder detergents<\/li>\n<\/ul>\n<p>Powder detergents mainly contain sodium sulfate and other salts. They are used for avoiding caking and increasing volume. Sodium carbonate helps decompose grease and soil. It allows them to dissolve in water.<\/p>\n<p>Oxidizing agents (such as sodium percarbonate) achieve mild bleaching. The powder detergent formula is more stable. But solid detergents require manual dosing. They cannot be dosed by dispensers. For large-scale laundry plants, manual dosing easily leads to errors. And the dosage is inaccurate.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-full wp-image-18369\" src=\"https:\/\/kingstarlaundry.com\/wp-content\/uploads\/2026\/07\/powder-detergent.jpg\" alt=\"\" width=\"1920\" height=\"1080\" srcset=\"https:\/\/kingstarlaundry.com\/wp-content\/uploads\/2026\/07\/powder-detergent.jpg 1920w, https:\/\/kingstarlaundry.com\/wp-content\/uploads\/2026\/07\/powder-detergent-300x169.jpg 300w, https:\/\/kingstarlaundry.com\/wp-content\/uploads\/2026\/07\/powder-detergent-1024x576.jpg 1024w, https:\/\/kingstarlaundry.com\/wp-content\/uploads\/2026\/07\/powder-detergent-768x432.jpg 768w, https:\/\/kingstarlaundry.com\/wp-content\/uploads\/2026\/07\/powder-detergent-1536x864.jpg 1536w, https:\/\/kingstarlaundry.com\/wp-content\/uploads\/2026\/07\/powder-detergent-18x10.jpg 18w, https:\/\/kingstarlaundry.com\/wp-content\/uploads\/2026\/07\/powder-detergent-600x338.jpg 600w\" sizes=\"(max-width: 1920px) 100vw, 1920px\" \/><\/p>\n<ul>\n<li>Liquid detergents<\/li>\n<\/ul>\n<p>Water is the main ingredient of liquid detergents. Other components require careful preparation for stability and effectiveness, such as surfactant, alkaline salt, chelating agent, and water softener.<\/p>\n<p>Surfactants include ionic and non-ionic surfactants. Non-ionic surfactants are liquids, which are suitable for suspending grease stains. It is not prone to forming soap scum. It is not suitable for powder detergents. Preservatives are often added to liquid detergents to prevent microbial growth.<\/p>\n<p>Unlike powder detergents, peroxide bleaching agents which can kill microbes are not used in liquid detergents. So mold and bacteria easily grow inside <a href=\"https:\/\/kingstarlaundry.com\/ar\/commercial-coin-operated\/coin-operated-softmount-washer\/\"><strong><u><b>washer<\/b><\/u><\/strong><\/a>s. Liquid detergents depend more on optical brighteners.<\/p>\n<ul>\n<li>Selection methods<\/li>\n<\/ul>\n<p>Detergent selection depends on its performance, cost, environment, and preference. The water density is 1kg\/L. So liquid detergents have a higher transport cost. Compared with powder detergents, they can be used directly. And they do not need complex dosing systems. Solid detergent systems compress powder detergents into blocks. Washing solution is made by rinsing on site.<\/p>\n<h2><strong>Other<\/strong><strong>\u00a0Ingredients<\/strong><\/h2>\n<ul>\n<li>Enzyme<\/li>\n<\/ul>\n<p>Enzymes can accelerate chemical reactions. It is used for specific protein-based stains. For example, lipase decomposes fat. Protease breaks down proteins. Amylase is used for starch and sugar. These enzymes come from microbes adapted to cold environments. Therefore, they can work in a regular wash temperature. Excessive heat deactivates the enzyme. The ideal wash temperature is 15\u201320\u2103. For example, half the dosage of high-enzyme powder detergents used under 20\u2103\u00a0achieves effective and eco-friendly results.<\/p>\n<ul>\n<li>Chlorine bleach<\/li>\n<\/ul>\n<p>Chlorine bleach\u00a0contains sodium hypochlorite. It decomposes food, sweat, and grass stains. It can eliminate bacteria, fungi, and viruses. It is effective to clean towels and bedding.<\/p>\n<p>Chlorine bleach\u00a0is highly corrosive. It damages delicate or non-white textiles. Check wash labels and do a spot test before use. Do not blend it with ammonia or acid detergents. This generates poisonous chlorine. It is not effective at removing grease stains.<\/p>\n<ul>\n<li>Oxygen bleach<\/li>\n<\/ul>\n<p>Oxygen bleach\u00a0often uses hydrogen peroxide or its releasing compounds (such as sodium percarbonate and sodium perborate). Compared with chlorine bleach, it is gentler and safer. It applies to most colored or delicate fabrics. Oxygen bleach\u00a0does not remove dyes. Hydrogen peroxide also has mild antibacterial functions. It breaks down into eco-friendly water and oxygen.<\/p>\n<p>Oxygen bleach\u00a0can remove light stains. It can also achieve whitening. But it may not work effectively on stubborn stains. It has a better performance in warm or hot water.<\/p>\n<ul>\n<li>Fabric softener<\/li>\n<\/ul>\n<p>Fabric softener deposits a chemical coating on fiber surfaces. It changes fiber texture and reduces static. Cationic surfactants combine with negatively charged fibers. This forms a smooth surface. And it makes fabrics softer. This coating can also neutralize charges to reduce static. Garments can be separated easily.<\/p>\n<p>Fabric softener reduces the friction among fibers. Garments can be ironed easily and have fewer wrinkles. But it reduces fabric water absorbency (such as towels). So after use, fully rinse garments. This helps reduce the residues.<\/p>\n<ul>\n<li>Neutralizer<\/li>\n<\/ul>\n<p>In a commercial laundry process, neutralizers are used for neutralizing alkaline residues. It also maintains the fabric softness to reduce skin irritation. Neutralizers (such as acetic acid and citric acid) adjust the fabric pH to a neutral level. They also restore fabric softness. In hard water areas, they remove mineral buildup. This helps prevent yellowing.<\/p>\n<p>Excessive use damages fabrics. According to the chemical supplier\u2019s guidance, ensure neutralizers are compatible with detergents. In a professional laundry process, neutralizers are essential to achieve high-quality and residue-free results.<\/p>\n<h2><strong>Conclusion<\/strong><\/h2>\n<p>In correct use, modern laundry chemistry is safe and efficient. Any improper dosage may lead to issues inside washers, even in the drying and ironing process. Pay attention to wearing personal protective equipment when using chemicals. Direct skin contact may cause harm.<\/p>\n<h2><strong>Q&amp;A<\/strong><\/h2>\n<p>Q1: Can a Kingstar washer dose powder chemicals?<\/p>\n<p>A1: Yes. Add chemicals to soap cups before washing. The washer can automatically dose chemicals according to different programs. But it is required to dose chemicals before each wash.<\/p>\n<p>Q2: Can neutralizers be used for garment washing?<\/p>\n<p>A2: Add neutralizers if garments are treated with high-alkaline detergents.<\/p>\n<p>Q3: How many dosing points does a Kingstar wet cleaning machine have?<\/p>\n<p>A3: Nine.<\/p>","protected":false},"excerpt":{"rendered":"<p>Professional laundry shops should know fabric composition and stain types.
