Types of Stains & Chemistry to Remove them
A number of substances that can stain clothes, linen or furnishings and some can be stubborn to remove. A range of stains removing chemicals from clothes can help us to do this job, which depends on these types of stains. Stains will often have more than one characteristic, hence a mix of chemical agents are often used to facilitate their removal.
TYPES OF STAINS:
Enzymatic stains are stains removed using enzymes, which are stain removers. Examples are blood stains, grass stains, chocolate stains, etc. Because stains are made of different types of molecules, a range of enzymes are needed to break them down. Proteases break down proteins.
These are good for Blood, Egg, Gravy, and other protein stains. Amylases break down starches, and lipases break down fat and grease. Washing powder usually only contains one type of enzyme, though some have two or all three.
Oxidizable stains include tea stains, coffee stains and wine stains. greasy stains etc. The most practiced way to remove oxidizable stains is by using oxidizing agents. The most common oxidizing agent is bleach, which is used to remove oxidizable stains.
Bleach oxidizes the color to become colorless. Hence, it is used as stain remover. Chlorine bleach is the most powerful stain removal agent. Chlorine bleach is mixed with water and then it is used in washing clothes.
Stains on the Surface and Surfactant Stains:
Stains like oil, grease or dirt are called surfactant stains. These stains are best removed by the use of surfactants.
Water is a polar substance, that means it mixes with the polar substance only. Oil and grease have characteristics of non-polarity, hence oil and grease cannot be washed in only water.
Surfactants surface active agents. They are derived from fats having polar and non-polar characteristics. Surfactants are very useful when they are incorporated with the laundry detergents. Being a part of laundry detergent surfactants plays multiple roles in removing the stains out of clothes.
First they penetrate and wet the fabric, second, they loosen the dirt or soil in the fabric and third, bring the soil particulates together to suspend in the water. This suspension allows the fabric to be cleaned, as the surfactant molecules have surrounded the oil stains which can then easily be washed by water.
Chemicals used by Restaurants and Resorts:
Here we will discuss those agents that are vastly used in hotels, restaurants or resorts by the housekeeping department. Why cleanliness is important in a hotel.

In hotels or in housekeeping departments multi-purpose cleaning agents are getting popular which also saves money. Liquid agents can be adulterated with water or even applied directly to dry clothes. Popular cleaning agents include Ammonia Methylate, Spirits, Paraffin, Turpentine, Vinegar, Hydrochloric Acid and Carbon Tetrachloride. We will try to understand their applications in brief.
It is a strong chemical compound of one nitrogen atom and three hydrogen atoms; ammonia can be easily integrated with water. It can reduce the hardness of water and can easily remove lubricants to get proper cleaning. Ammonia should be used in liquid form, along with other chemicals. Ammonia must be kept away from bleach as a combination of these two can produce a very hazardous methylated gas.

It is widely used as a dry cleaning solvent. It was used in fire extinguishers and served as a precursor to many refrigerants. Inhaling its vapor can damage the central nervous system and cause degeneration of the liver and kidney. Hence the use of this compound is phased out due to its toxic nature.
Tips for getting the perfect cleaning:
While using detergents it should be carefully seen that it is properly dissolved in water. To get a good result, the right quantity of detergent should be used, which is also good for cleaning. It is observed that detergents are more effective at high temperature of water, therefore using it with low temperature may not work properly until physical agitation power is applied to it.
Stain Removing Chemicals:
Acetic acid being a weak acid acts like a buffer in washing process. Acetic acid is a diluted form of white vinegar. Acetic acid, though mild, is strong enough to dissolve alkaline residue left by soap and detergents. It is safe to use acetic acid on silk and wool cloth; it can be used for cotton linen if diluted with equal part of water. It brightens, whitens, softens clothes and removes odor without harsh chemicals.
Acetones are often purchased generically at pharmacies and hobby shops. A colorless liquid that smells like peppermint, it is often used on stains caused by substances like fingernail polish or household cement. While it may not damage either natural fibers or most synthetics, it should be pretested to make sure that dyed fabrics won't be harmed. It should not be used on fabrics containing acetate.
Acetone is popularly used in textile industries for removing grease and removing gum from wool and silk. If inhaled it may cause a sore throat or cough. It is highly flammable, but has low acute and chronic toxicity.
Common iso-propanol (70%), which may be purchased generically at drugstores, is sufficient for many stain-removal jobs that make decisions about alcohol, although the stronger ethyl alcohol (90%) also can be used. make certain you do not buy alcohol with an added color or fragrance. If you want to use it on fibers within the acetate family, dilute the alcohol with two parts water. Caution: Alcohol is poisonous and flammable. Observe all label precautions.
Ammonia can remove various types of stains with minimal effort. Never mix ammonia with bleach or chlorine contained substance. The combination produces toxic fumes which are dangerous.
Ammonia is a very good deodorizer and a very good de-greaser. Take an empty spray bottle mix ammonia, laundry detergent and water. You can use this spay on stains of ink stains, grass stains, food stains etc. Wait at least 30 minutes before you wash them off.

It is effective in treating ink and rust stains. Oxylic acid is also called ethanedioic acid. Etanediodic crystals can also be found in pharmacies or specially-ordered from them. Before using the crystals, you must dissolve them in water (1 tablespoon crystals to 1 cup warm water). You may even be ready to purchase liquid ethanedioic acid at hardware stores.
Oxalic acid, when it is in a solid state, is colorless and odorless, but after purification takes the form of white crystalline substance. It is used to remove iron rust stains or yellowing of laundry caused due to iron deposits in water supply. Caution: Oxalic acid is poisonous. Wear rubber gloves and avoid contact with the skin and eyes, and also avoid being in contact with delicate clothes.
Sometimes available in crystal form at drugstores and photo supply houses. Hypos are additionally referred to as photographic "hypos" or fixers. Although considered safe for all fibers and harmless to dyes, it should be tested on an inconspicuous area of fabric before use.
