Chemicals
A wide range of car
wash chemicals is available with product choices to be made depending
on the equipment being used. For example, pre-soak detergents for
touchfree automatic equipment will generally be alkalis, designed for
superior penetration and suspension of soils, whereas pre-soak
detergents for brush machines are generally more neutral with higher
levels of lubricity to protect both the cars and the brushes
themselves.
Pre-soak, tyre and
engine cleaner, high pressure soap, foam brush and wax are the five
most common applications for self serve equipment and the best results
are usually achieved with application specific chemicals - though
products are available that can be used for multiple applications with
acceptable results.
Careful
consideration must also be given to environmental and O.H. &S issues,
with regulations governing permitted pH levels for instance.
