If we talk about cleaning supplies or often called the cleaner, we will know a lot of these types of substances. Some species, especially those that are multi-purpose, people used to clean surfaces and objects such as floors, walls, glass and others. While the cleaner is solvent or water based on commonly used in the industry such as hotels and large buildings.
However, to determine a good cleaner a lot of factors that need to be considered, because a good cleaner must meet certain requirements. Figure 4.18 Guest Room Hotel
Good cleaner in general must meet the following requirements:
a. Biodegradable which can be decomposed by micro-organisms, so it does not harm the environment or not pollute the environment.
b. Solubility is soluble in water and easily removed from the surface of the object to be cleaned.
c. Wetting is a strong wetting properties, to obtain these properties is necessary to surface active agents (surfactants) to lower the surface tension of water, so that wetting the cleaned surfaces can be fast.
d. Emulsification is the nature of the work cleaner break down waste into tiny particles.
e. Soil Suspension is already diimulsikan dirt suspended in the solution should be made to prevent sticking back on surfaces that have been cleaned, a substance that can provide these properties is called Emulsifier.
f. Rinsability are remnants of cleaning agents and dirt to be easily removed from surfaces that have been cleaned.
g. Desinfectant the ability to kill disease-carrying bacteria.
h. The pH cleaner must possess a certain acidity and to basaan (cleaner can be acidic, alkaline or neutral), but most of the dirt is acidic, so it requires an alkaline cleaner.
- Acid cleaning suplies properties (acidity) = pH <7
- Properties of alkaline cleaning suplies (alkalinity) = pH> 7
