Detergents: The do's and dont's

Surely I could use any old detergent?
Choosing the right detergent can significantly reduce the time and effort to clean. Detergent can be often carried out in a two step method;
Step one - application of the detergent to the surface, allowing it to soak the dirt.
Step two -High pressure cleaning and rinsing of the surface.

 

Then how does a good detergent work?
A good detergent will force in and soak into the dirt, until the high pressure water flushes the dirt and detergent off the surface. The efficient time between is the period between the two. Only dirt that has been properly soaked and absorbed the detergent can be efficienctly removed, and a suitable good detergent will keep the fat and oil emulsified so that they can be rinsed away

.

What sort of detergents are there?
Water based alkaline
The most popular and important detergent used with high pressure water, where natural or synthetic fats represent a considerable part of the dirt.

Water based neutral
Used for light cleaning when the dirt is easily soluble and is holding small amounts of fat and oil, and when hot water or a brush can also be used.

Water based acid
For descaling walls and floors and building renewals, or for descaling process equipment or scale removal especially in the food industry.

Solvent based
While highly efficient for de-waxing cars or cleaning tarpaulins, solvents are often more hazardous and usually less environmentally safe.

Foaming detergents
More often used in food industry, and now increasingly in automotive, air is introduced to give a non-stable foam to remain on the surface, providing a longer contact time.
