STEAM CLEANING & PRESSURE WASHING

Use 1 to 2 pints in replacement of each 4 pounds of powder normally used, or 1 ounce per gallon at the nozzle of the steam gun. The concentration may be as high as 1 part Safe-N-Clean to 1 part water in the solution tank. This is possible because there are no powders in Safe-N-Clean to fall out into the bottom of the tank, subsequently clogging small orifices, tubing, etc. Scale in the steam coils does not occur. This highly concentrated solution may be varied to fit any job by a single turn of a metering valve. Safe-N- Clean is safe on any surface that will tolerate steam.

In spray washing, the best results have been obtained by using high pressure, low volume equipment, i.e., 500 pounds pressure or higher and a volume of 2 to 3 gallons per minute. The best spray nozzle to use is the 20 degree Vee Jet type. The best method of application is to wet the surface to be cleaned with Safe-N- Clean and water, at the desired concentration. Let it stand until the soil on the surface is loose.

Concentrations will vary to fit the job, but 10 parts water to 1 part Safe-N-Clean is a good place to start. Always start at the bottom of the surface to be cleaned and apply the solution upwards, allowing the solution time to work. Let Safe-N-Clean do the hard job. The actual cleaning occurs during the rinse. Using the equipment described above, start the rinse operation at the top of the surface and rinse downwards. Hold the spray nozzle of the gun approximately 6-8 inches from the surface at a 45 degree angle and move forwards. This action causes the water to penetrate under the loosened soil and to roll it

forward in front of the spray nozzle. With very light mixtures of Safe-N-Clean in the rinse, the dirt or grime cannot re-adhere to the surface that has just been cleaned.
