There are many different types of cleaning solutions. Depending on the type of soils or stain, for example, water, glycol, hydrocarbon, alcohol, and chlorine base cleaning solutions each with distinct characteristics.
When choosing a cleaner, how well it can clean is one of the most important points. To increase cleaning power, it is important to enhance the absorption rate of the cleaner to the surface of the dirt and the key factor for absorption is surface tension and viscosity. A surface tension refers to fluid characteristic when it tries to decrease surface area. For it to penetrate soil better, decreased surface tension and low viscosity is necessary. Surface tensions are usually controlled by use of additives such as surfactant and its concentration. As for viscosity, in some cases, high viscosity is desired to keep the cleaning solution on the stain long. High viscosity lowers how much it penetrates beyond surface, but depending on the use of the cleaning solution, there is a proper balance. In the world of cleaning solutions, density and viscosity are managed and adjusted depending on the use of the product in order to have a high level of cleaning power.
