A stain is a discoloration that can be clearly distinguished from the surface, material, or medium found. They are caused by chemical or physical interactions of two different materials. Coloring is used for biochemical research, metal staining, and art (eg, wood staining, stained glass).

Jenis
There are intentional stains (such as wood or paint stains), indicative stains (such as food coloring or adding substances to make bacteria visible under a microscope), natural stains (such as rust on iron or patina on bronze), and unintentional stains such as tomato sauce on the shirt.
Different types of materials can be colored by different substances, and stain resistance is an important characteristic in modern textile techniques.

Formation
The main method of stain formation is the surface stain, where the dye spills onto the surface or material and is trapped in fibers, pores, grooves, or other capillary structures on the surface. The trapped material coats the underlying material, and the stain reflects back the light according to its own color. Applying paint, spilled food, and wood stains is this trait.
The secondary staining method involves chemical or molecular reactions between materials and staining materials. Many types of natural stains fall into this category.
Finally, there can also be molecular attraction between the material and the coloring material, which involves being held in a covalent bond and indicating the color of the bonded substance.
Properties
In many cases, the stain is affected by heat and can become quite reactive to bond with the underlying material. Extreme heat, such as from ironing or dry cleaning, can cause a chemical reaction to a removable stain, turning it into an unlikely chemical compound.
Deletion
Various washing techniques exist to try to eliminate or minimize the stain that exists, and stain remover is an important type of chemical in laundry detergents. Some stand-alone stain remover also exists. If the wrong technique is used to remove stains or stains on the clothes it could actually cause permanent damage to the clothes.
