The biggest problem that one faces is of removing of stains. Stains can include anything. It can be a stain of lemon juice or some chemical stain on the cupboard. There are stain removers available in the market. But there are basically three kinds of satin removers and they are bleaches, emulsifiers and solvents. All stain removers work on some basic principles. Here are the principles on which the stain removers work.
This is the most commonly used stain removers in the household. There are many kinds of bleaches that are available in the market. If you opt for chlorine based bleaches then they will assist you in wiping out the molecules that are responsible for color. Chlorine based bleaches are strong and corrosive and can even damage fabrics. Another kind of bleach is the Hydrogen peroxide one which is also equally good.
Another kind of stain remover is the solvent based. Solvents dissolve substances and wash them away from the surface. Petrol, benzene, trichloroethylene, acetone are some organic solvents while water and acids may be termed inorganic solvents.
Oil is not soluble in water. Similarly there are substances which are not soluble in water. Emulsifers are compounds which help bind these substances to water, loosen them from the surfaces to which they are clinging and be washed away. Soap is the best known emulsifier to common man.
Nowadays detergents and cleaning agents come enriched with industrial enzymes which help in breaking down the dust and dirt molecules which can then be easily washed away.
