English For fabrics with heavy dirt and stubborn stains such as dyes, grease, motor oil, lipstick, and food stains…, ordinary washing may not be sufficient to completely clean them. Therefore, spot cleaning is necessary before the laundry process. Let’s explore the spot-cleaning method in the industrial laundry with Thai Tuan LMS!
What is spot cleaning?
Spot cleaning is a method that uses specialized chemicals to remove tough stains from fabrics. This process focuses only on treating the specific areas with heavy and stubborn stains.
To effectively spot clean tough stains, the following chemicals are commonly used:
- Solvents
- Stain hydrolysis aid
- Alkaline solutions
- Acids
- Bleaching agents
Advantages of the Spot Cleaning Method
Spot cleaning tough stains before washing offers many benefits:
- It cleans stubborn stains: Spot cleaning uses stronger chemicals than regular laundry detergents, effectively removing tough stains like grease, ink, wine, blood, etc.
- Saves time and chemicals: Instead of sending everything for a wash and possibly having to wash it all again, spot cleaning focuses only on the heavily stained areas, helping to save time and chemicals.
Notes When Using the Spot Cleaning Method
Each type of stain requires a specific spot-cleaning agent to suit the fabric's characteristics. When performing spot cleaning, pay attention to:
- Determining the type of stain: Understand the source of the stain and where the fabric is being used.
- Type of fabric: Each type of fabric has different washing and treatment methods.
- Colorfastness: Use a small piece of fabric to test the colorfastness. Additionally, you can rely on sensory perception to identify stains, including their texture (hard/soft), feel (smooth/sticky), and smell (meat, fish, beer, perfume, etc.).
Currently, there are many different spot cleaning agents on the market, varying in chemical composition and functionality. The spot cleaning process should be carried out by skilled personnel familiar with the procedures and capable of distinguishing fabric types and cleaning agents to enhance cleaning effectiveness and ensure safety.
General Rules When Using the Spot Cleaning Method in Laundry
- Absolutely do not mix dry solvents with water or wet solutions with other chemical solutions.
- Using diluted chemical concentrations may slow down the stain removal process but is gentler on the fabric compared to using concentrated chemicals.
- Never allow spot cleaning agents to come into contact with the stain for more than 10 minutes.
- After testing one type of cleaning agent, ensure thorough rinsing before trying a different one.
Spot Cleaning Process in Industrial Laundry
After receiving heavily soiled fabrics from the sorting area, the spot-cleaning process should follow these steps:
Step 1: Check the type of stain and fabric
Identify the type and stubbornness of the stain and carefully examine the fabric's color fastness to choose an appropriate cleaning agent.
Step 2: Select the spot-cleaning chemical
After correctly identifying the stain, dilute it as instructed, and attach the cleaning agent to the spot cleaning gun.
Step 3: Perform spot cleaning
Choose suitable tools for spot cleaning (cotton, soft cloth, spot cleaning gun, etc.), soak in the spotting agent, and apply it to the stain. Allow it to dry and check again.
Step 4: Rinse
After treating the stain, proceed with the further steps of laundering.
Spot cleaning is a widely used method in industrial laundering to remove heavy stains. To ensure optimal results from this method, adhere to the general rules mentioned above.
