Cleaning agents are substances (usually liquids, powders, sprays, or granules) used to remove impurities, including dust, stains, foul smells, and clutter on the surface. Purpose of cleaning agents include health, beauty, odor removal, and avoid the spread of dirt and contaminants to yourself and others. Some cleaning agents can kill bacteria, eg. on the door handle, work surface and other metal surfaces, and clean at the same time. Others, called degreasers, contain organic solvents to help dissolve oils and fats.

Acid
The acid cleaning agent is mainly used to remove inorganic deposits such as scaling. The active ingredient is usually a strong mineral acid and chelant. Often, surfactants and corrosion inhibitors are added to the acid.
Hydrochloric acid is a common mineral acid normally used for concrete. Vinegar can also be used to clear hard surfaces and eliminate calcium deposits. Sulfuric acid is used in acid duct cleaners to unblock clogged pipes by dissolving fats, proteins, and even carbohydrate-containing substances such as toilet paper.

Alkaline
The alkaline cleaning agent contains strong bases such as sodium hydroxide or potassium hydroxide. Bleach (pH 12) and ammonia (pH 11) are common alkaline cleaning agents. Often, dispersants, to prevent the redeposition of dissolved impurities, and chelants, to attack the rust, are added to the alkaline agent.
Alkali cleansers can dissolve fats (including fats), oils, and protein-based substances.
Neutral
Neutral washing agents are neutral pH and are based on non-ionic surfactants spreading different types.
Degreaser
A cleansing agent specially made to remove fat is called a degreaser. It may be solvent-based or contain solvent and metamorphic.
Type
Versatile cleaners
The multipurpose cleaners contain mixtures of anionic and nonionic surfactants, polymeric phosphates or other decomposers, solvents, hydrotropic substances, polymeric compounds, corrosion inhibitors, skin protection agents, and sometimes fragrances and dyes.
Some cleansers contain water-soluble organic solvents such as glycol ether and fatty alcohols, which facilitate the removal of oils, fats and paints. Disinfectant additives include quaternary ammonium compounds, phenol derivatives, terpene alcohols (pine oil), aldehydes, and aldehyde-amine condensation products.
Multipurpose cleaners are effective with the most common types of impurities. Their aqueous solutions are neutral or weakly alkaline, and are safe to use on most surfaces.

Metal cleaner
The metal cleaner is used to clean the stainless steel sink, tap, metal, silver, etc. This product contains abrasive materials (eg, lime containing silica, diatomic soil, alumina) with particle size & lt; 20 m? Fatty alcohols or ethylene oxide (EO) polyglycol ethers (EO) are used as surfactants.
Stainless steel, nickel, and chromium cleaners contain lactic acid, citrate, or phosphate. Solvents (alcohol spirits) can be added.
Nonferrous metal cleaners contain ammonia, ammonium soap (ammonium oleate, stearate) and chelating agents (ammonium citrate, oxalate).
Silverware can be released from tarnish sulfide silver with thiourea, and hydrochloric or sulfuric acid.
