Cleaning Trucks
Fleet washing the units on the company’s site is perhaps the most profitable method of cleaning trucks. The cleaning unit is set up in one position and the drivers bring the trucks through as though it was a car was. (more…)

Removing Various Stains

Smoke Stain
Some smoke stains cannot be removed. If exposed to high temperature, as in fire, there is nothing that removes it. Sandblasting does not remove the stain, just the face of the brick. Smoke stains on the face of a fireplace as a result of lighting a fire with the damper closed can be removed easily. A commercial cleaning agent obtainable from a chemical company works very well. Mix solution according to manufacturer’s instructions, and cover carpet and surrounding areas that may be splattered during cleaning. (more…)
Chemicals and Stain Removers
January 29th, 2010 vdate 
The removal of stains at times is a hit and miss proposition. Although the nature of stains is known, successful removal is not always possible. Application of an incorrect cleaning agent can set a stain, making it impossible to remove. It can also damage adjacent areas without having a favorable effect on the stain. Before applying a chemical cleaning agent to an entire stain, clean a small area in an inconspicuous spot to test it.
How To Extend The Lifetime Of Your Pressure Washer Hose.
January 6th, 2010 vdate 
Hoses
In the high-pressure washer industry, proper hose care and maintenance is not only essential for full service life, it is also necessary to ensure the safety of any washer operator. A hose blowout doesn’t just mean an extra mess to clean up or a new hose to buy. During a blowout, high-pressure water, in many cases at high temperature, escapes from the hose and can possibly injure the operator or anyone nearby. This added safety concern is why it is of the utmost importance to know when a hose should go. (more…)

Theoretical Spray Angles
Theoretical Spread and Spray Angle Coverage
Although nozzle spray patterns are expressed in degrees of spread, these figures are not precisely accurate as the distance between the cleaning surface and the nozzle increases, which is why the terms theoretical spread or theoretical coverage are used. Theoretical spray angles indicate approximate spray coverage’s based on water velocity. In actual use the spray angle varies with distance. (more…)
Heating Systems
December 11th, 2009 vdate 
Heated pressure washers and steam cleaners increase the ability of a high-pressure flow of water to break down dirt and grease. They also increase the action of most cleaning detergents. These systems are very complex, and add more potential personal injury and property damage hazards. Design of these systems requires additional components as well as experienced design personnel with knowledge of fuels, heat transfers, electronics, etc. (more…)
Unloaders and Valves
December 9th, 2009 vdate 
The spray gun and unloader make up a two-part valve system that directs water into bypass and back to the pump or float tank. The spray gun shuts off the flow of water causing the unloader to recirculate the water back into the inlet side of the pump. This is called sending the water into bypass. Pressure-actuated unloaders are opened by the increase in pressure occurring when the valve in the spray gun closes. Flow-actuated unloader valves send water into bypass when flow drops. (more…)
