What is the primary cleaning agent in most spotters?

The primary cleaning agent in most spotters is typically water, often combined with surfactants or solvents. Water serves as a universal solvent, allowing it to interact with a wide variety of stains and contaminants typically found on upholstery and fabrics. When combined with surfactants, which lower the surface tension of water, the effectiveness of the cleaning process is significantly enhanced. Surfactants help to loosen and lift dirt and stains from the fabric, making them easier to remove.

While organic solvents and alcohol-based solutions can be effective for specific stains, they are not the primary agents found in the majority of spotters, which tend to rely heavily on the versatility and availability of water. Acidic solutions may be beneficial for particular types of stains, but they are not as broadly applicable as water-based solutions and could potentially damage certain fabrics. Therefore, water with surfactants or solvents is the most commonly used and effective cleaning agent in upholstery cleaning spotters.
