Alkaline cleaning agents contain strong bases like sodium hydroxide or potassium hydroxide. Bleach (pH 12) and ammonia (pH 11) are common alkaline cleaning agents. Often, dispersants, to prevent redeposition of dissolved dirt, and chelants, to attack rust, are added to the alkaline agent.
Alkaline chemicals break down known soils such as grease and mud. Acids break down soils such as lime scale, soap scum, and stains of mustard, coffee, tea, and alcoholic beverages. Some solvent-based products are flammable and some can dissolve paint and varnish. Disinfectants stop smell and stains caused by bacteria.
Stain removal is possible due to hydrophilic end and hydrophobic end present in detergents. The hydrophilic end of the detergent attaches itself to the water molecules while the hydrophobic end attaches itself to the material and the molecules of the stain. The hydrophilic end allows for the stain molecules to be water soluble.

Dishwasher detergents are generally strongly alkaline . [6] Inexpensive powders may contain sand [citation needed]. Such detergents may harm the dishes and the dishwasher. Powdered detergents are more likely to cause fading on china patterns. [7] Besides older style detergents for dishwashers, biodegradable detergents also exist for dishwashers ...
Detergents. A detergent is a surfactant or a mixture of surfactants with cleansing properties when in dilute solutions. [1] There are a large variety of detergents. A common family is the alkylbenzene sulfonates, which are soap-like compounds that are more soluble than soap in hard water, because the polar sulfonate is less likely than the polar carboxylate of soap to bind to calcium and other ...
Dishwashing liquid (washing-up liquid in British English), also known as dishwashing soap, dish detergent, or dish soap, is a detergent used in dishwashing. Dishwashing detergent for dishwashers comes in various forms such as cartridges, gels, liquids, packs, powder, and tablets. [ 1 ]
A strong acid, such as hydrochloric acid, at concentration 1 mol dm −3 has a pH of 0, while a strong alkali like sodium hydroxide, at the same concentration, has a pH of 14. Since pH is a logarithmic scale, a difference of one in pH is equivalent to a tenfold difference in hydrogen ion concentration.
