NOTE

HOUSEHOLD LAUNDRY: DRY CLEANING I

Household laundry refers to the process of washing, drying, and caring for clothing and other textiles within a household setting. This typically involves using a washing machine and dryer, along with laundry detergent and other cleaning products, to clean and maintain clothing and linens.

Dry cleaning agents

Dry cleaning agents used for cleaning clothes include:

  1. Perchloroethylene (PERC): This is one of the most common solvents used in dry cleaning. It effectively removes stains and dirt from fabrics without causing damage.
  2. Hydrocarbon Solvents: Hydrocarbon solvents, such as Stoddard solvent or petroleum-based solvents, are also used in dry cleaning. They are less harsh than PERC and are often preferred for delicate fabrics.
  3. Green or Eco-Friendly Solvents: With growing environmental concerns, some dry cleaners use alternative solvents that are more environmentally friendly, such as liquid carbon dioxide or silicone-based solvents.
  4. Detergents and Spot Treatments: Dry cleaners may use specialized detergents and spot treatments to pre-treat stains before dry cleaning. These products help to loosen and remove stains effectively.
  5. Steam Cleaning: In addition to solvents, dry cleaners may use steam cleaning machines to remove wrinkles and freshen fabrics without the use of harsh chemicals.

General rules for removing stains during dry cleaning

  1. Identify the Stain: Determine the type of stain and its source before attempting to remove it. Different stains may require different treatment methods.
  2. Pre-Treat Stains: Apply a small amount of spot treatment or detergent directly to the stain and gently blot with a clean cloth or sponge. Avoid rubbing the stain, as this can spread it further.
  3. Communicate with the Dry Cleaner: Inform the dry cleaner about any stains or spots on your clothing before sending them for cleaning.
  4. Avoid DIY Stain Removal: Some stains, especially those on delicate or expensive fabrics, are best left to professional dry cleaners. Attempting to remove certain stains at home can cause further damage to the fabric.
  5. Prompt Action: Act quickly to address stains before they set into the fabric. The longer a stain sits, the more difficult it may be to remove during the dry cleaning process.
