Cleaning Products
Most cleaning compounds consist of the same basic chemicals. Depending on the purpose for which
they are intended, there may be variations in the concentration of the different ingredients in the formula-
tion, or perhaps a different type of chemical used to give the compound specific characteristics.
In order to cover a very broad range of applications, there are what is referred to as general-purpose or
all-purpose cleaners, and for very specific applications, there are specialty or use specific cleaning
compounds.
The great majority of commercially available cleaners fall into the general-purpose category. A good
general purpose cleaner will contain detergents, alkaline builders, and most likely, a degreaser of one of
several types.
Detergents have the effect of reducing the surface tension of plain water, thus making the water "wetter"
to enable soils to be released and held in suspension more easily. Alkaline builders increase the ph level
of the compound to an effective aggressiveness for the application. Degreasers aid in loosening soils
that require a solvent other than a detergent.
Certain cleaning compounds that are sold as use specific cleaners may contain added chemicals that
produce very dramatic results with a minimum of effort. But these cleaners are also so aggressive that
they must be handled and applied with a great deal of care, and may damage the surfaces on which
they are used.
Compound sold as "deck cleaners", which contain high concentrations of acids or caustic sodas, fall into
this category.
