It is effective in removing oil stains, adjusting the pH level, as well as softening water. It is suitable for workwear, cotton and linen, as well as heavily soiled garments.<\/p>\n<ul>\n<li>Operations<\/li>\n<\/ul>\n<p>&#8211; Heavy oil stain pre-treatment<\/p>\n<p>Add sodium carbonate to warm water. Apply the paste to the stained areas. Leave it for 10-20 minutes. Then wash as usual after gently brushing.<\/p>\n<p>&#8211; Enhance cleaning performance<\/p>\n<p>Add half a cup of sodium carbonate to warm water. Dissolve it completely before dosing it into the washing machine. In the Kingstar wet cleaning machine, dose the sodium carbonate into its detergent dispenser. It can dissolve the additive in water and dose it into the drum through siphoning. This helps prevent clumping and localized fabric damage.<\/p>\n<p>&#8211; Color care for cotton and linen<\/p>\n<p>Dose one-third or half a cup of sodium carbonate into each machine. It can help maintain garment color and brightness. Test colorfastness first.<\/p>\n<ul>\n<li>Cautions<\/li>\n<\/ul>\n<p>Sodium carbonate has high alkalinity. Wear gloves during operations. It cannot be used for delicate fabrics (such as wool, silk, and lace). Excessive usage can cause stiff hand feel and color damage. Make sure the laundry is rinsed thoroughly.<\/p>\n<h2><strong>Sodium Sesquicarbonate<\/strong><\/h2>\n<p>Sodium sesquicarbonate is a compound of sodium carbonate and sodium bicarbonate. The alkalinity is between sodium bicarbonate and sodium carbonate. It can be used for water softening, light-to-moderate stain removal, as well as odor elimination.<\/p>\n<ul>\n<li>Operations<\/li>\n<\/ul>\n<p>&#8211; Regular dosage<\/p>\n<p>Dose a quarter or half a cup of sodium sesquicarbonate per machine together with detergents. It is suitable for daily garment cleaning in hard-water areas.<\/p>\n<p>&#8211; Stain removal &amp; soak<\/p>\n<p>Sodium sesquicarbonate should be dissolved in warm water. Garments can be soaked for about 30-60 minutes. Then wash as usual.<\/p>\n<p>&#8211; Eliminate odors &amp; care<\/p>\n<p>Dose a quarter cup of sodium sesquicarbonate per machine. This can reduce sweat and musty odors.<\/p>\n<p>&#8211; Colored garments<\/p>\n<p>It is gentle on colored cotton and linen fabrics. Test on an inconspicuous area first.<\/p>\n<ul>\n<li>Cautions<\/li>\n<\/ul>\n<p>Skin-sensitive operators should wear gloves. Check care labels before washing delicate fabrics. Do not mix it with chlorine bleach. Excessive usage can leave alkaline residues.<\/p>\n<h2><strong>Sodium Percarbonate<\/strong><\/h2>\n<p>Sodium percarbonate is an oxygen-based bleach. It is often used in laundry shops. It can release active oxygen after dissolving in warm water. It can remove stains, whiten fabrics, eliminate odors, as well as support disinfection. It is milder than chlorine bleach. It is suitable for white garments and many colored clothes.<\/p>\n<ul>\n<li>Operations<\/li>\n<\/ul>\n<p>&#8211; Regular whitening<\/p>\n<p>Add 1-2 tablespoons of sodium percarbonate into the detergent dispenser of the Kingstar wet cleaning machine together with laundry powder. A water temperature of 40-60\u2103 can achieve better cleaning performance.<\/p>\n<p>&#8211; Soak &amp; stain removal<\/p>\n<p>Add 1-2 tablespoons of sodium percarbonate (per 5 L of warm water). Garments can be soaked for 30 minutes to 2 hours. It is suitable for removing coffee, wine, grass, as well as collar yellowing stains.<\/p>\n<p>&#8211; Whiten white garments<\/p>\n<p>For white cotton and linen garments, use laundry powder with 60\u2103\u00a0water. Do not use chlorine bleach.<\/p>\n<p>&#8211; Oxygen bleaching for colored garments<\/p>\n<p>These garments are suitable for 30-40\u2103\u00a0water. Test colorfastness first to prevent dark-color fading.<\/p>\n<p>&#8211; Support disinfection<\/p>\n<p>Follow production instructions. Choose the proper temperature and time. It is suitable for towels and bedding.<\/p>\n<ul>\n<li>Cautions<\/li>\n<\/ul>\n<p>Sodium percarbonate is effective in warm water. It can release oxygen in a closed container. Leave room for gas release during storage and soaking processes. Do not mix it with chlorine bleach, acid, and reducing agents. It is not suitable for wool and silk. Test dark garments first.<\/p>\n<h2><strong>Operation Cautions<\/strong><\/h2>\n<ul>\n<li>Identify<\/li>\n<\/ul>\n<p>Check care labels, fabrics, stains, and water quality.<\/p>\n<ul>\n<li>Dissolve<\/li>\n<\/ul>\n<p>Sodium carbonate and sodium percarbonate should be dissolved in water first before dosing into the machine. This can reduce local garment damage.<\/p>\n<ul>\n<li>Use the right dosage<\/li>\n<\/ul>\n<p>Test on a small area before processing in a batch.<\/p>\n<ul>\n<li>Sort by color &amp; fabrics type<\/li>\n<\/ul>\n<p>Besides white and colored garments, towels and delicate fabrics should be separated.<\/p>\n<ul>\n<li>Record wash details<\/li>\n<\/ul>\n<p>For example, record water volume, temperature, chemical dosage, as well as soaking time for reviewing rewash results.<\/p>\n<ul>\n<li>Rinse thoroughly<\/li>\n<\/ul>\n<p>Chemical residues can affect fabric feel or irritate skin. Proper rinsing can remove residual chemicals.<\/p>\n<h2><strong>Conclusion<\/strong><\/h2>\n<p>Choose sodium bicarbonate for light stains, odors, as well as daily garment care. Sodium carbonate can be used for removing heavy oil stains. Sodium sesquicarbonate is suitable for softening water and stain removal. Sodium percarbonate can help remove yellowing, whiten fabrics, act as an oxygen bleach, and disinfect. The four laundry additives should be used for the right applications and at proper dosages and temperatures.

This can damage garments. Without the pre-wash cycle, the cleaning performance can be reduced. The Kingstar detergent dispenser can ensure that detergents are dosed at the proper stage. The dissolved laundry chemicals can be automatically dosed without opening the door during the wash cycle.<\/p>\n<p>Q2: Does a Kingstar wet cleaning machine have preset programs?<\/p>\n<p>A2: Some programs have been set for direct use.
