Question 1: About the choice between dry cleaning and water washing for clothes
Choosing between dry cleaning and water washing is not about which method is more upscale, but about selecting the washing method that best suits the fabric, stains, and decorations of the clothing. In fact, in compliant laundry shops that meet national standards, the cost of water washing is not lower than dry cleaning. In Chinese laundries, water washing accounts for about 50% of the total washing business, while in developed countries in Europe and America, it can exceed 60%.
Simply put: clothes suitable for dry cleaning mainly include suits, formal wear, silk fabrics, wool, cashmere, fur, etc. Clothes suitable for water washing mainly include ordinary shirts, down jackets, artificial leather, fine cotton fabrics, clothes with elastic bands, synthetic fibers (polyester, nylon, etc.), and clothes with special decorations.
Question 2: About tetrachloroethylene as a dry cleaning solvent
Dry cleaning is a washing method that uses organic solvents (tetrachloroethylene, hydrocarbon solvents, etc.) to clean clothes and remove oil stains or dirt without water. The advantage of dry cleaning is its significant effect on removing oily stains from clothes, good shape retention, no fading, and it can also sterilize and prevent moth damage.
Tetrachloroethylene is the most commonly used dry cleaning agent internationally. Due to its excellent stain removal performance and safety, currently more than 80% of dry cleaning machines worldwide (including developed countries in Europe and America) use tetrachloroethylene as the cleaning solvent. The claim that tetrachloroethylene has been banned as a dry cleaning agent in the United States for many years is unfounded.
Tetrachloroethylene is an organic solvent with certain toxicity and strong volatility. Standard laundries use fully enclosed dry cleaning machines to wash clothes, involving processes such as distillation, drying, and recovery. Afterwards, clothes are ironed and shaped at high temperatures, so there is no tetrachloroethylene residue on the cleaned clothes. Just like in paper making, leather production, grain, vegetables, etc., certain toxic substances are involved during production, planting, and processing. The key is whether the final product meets all quality standards.
Question 3: About the use of detergents (washing powder, soap) and brushing clothes
The washing and dyeing industry strictly prohibits the use of unqualified detergents. Washing powders, soaps, detergents, auxiliaries, and stain removers produced by regular manufacturers are standard supplies in washing and dyeing enterprises and can be used. Laundry technicians should reasonably use detergents, auxiliaries, and stain removers according to the contamination level of the clothes.
Brushing is a common washing technique in the washing and dyeing industry, but it should be strictly performed according to the "three flats and one even" method (i.e., flat washing board, flat laying of clothes, flat brushing, and even force) to ensure stain removal without damaging the fabric structure.
Question 4: About laundry costs and the issue of "excessive profits"
The laundry industry is highly competitive and does not have so-called excessive profits exceeding ten times the cost.
The washing cost of a compliant laundry shop includes rent, personnel fees, various insurances, washing solvents, chemical auxiliaries, and more importantly, equipment purchase, maintenance, and professional renovation costs of the laundry shop.
To regulate industry charging standards, the Professional Committee of Washing and Dyeing conducts annual laundry price surveys and publicly announces the price ranges and national average prices for clothing, so consumers can understand the costs. Laundry shops must clearly display laundry prices in the store and advocate price negotiation and value-preserving washing for high-end clothes (luxury goods).
