The use of detergents can dramatically
reduce cleaning time and assist in the
removal of difficult stains. Some
detergents have been customized for
pressure washer use on specific cleaning
tasks. These detergents are approximately
as thick as water. The use of thicker
detergents, such as dish soap, will clog the
chemical injection system and prevent the
application of the detergent.
The cleaning power of detergents comes
from applying them to a surface and
giving the chemicals time to break down
the dirt and grime. Detergents work best
when applied at low pressure.
The combination of chemical action and
high pressure rinsing is very effective. On
vertical surfaces, apply the detergent
starting at the bottom and work your way
upward. This will prevent the detergent
from sliding down and causing streaks.
High pressure rinsing should also progress
from the bottom to top. On particularly
tough stains, it may be necessary to use a
brush in combination with detergents and
high pressure rinsing.
