- The type of cleaning agents and concentration levels will dictate chemical actions.
- Chemicals will breakdown and emulsify soils as well as reduce static charge.
- Certain chemicals assist in drying and shining the vehicle.
- The lower the temperature, the lower the viscosity.
- As the temperature rises, less chemistry is required to do the same job.
3. Water Quality
- Hard, soft, RO or reclaim water?
- Hard water will decrease cleaning and create deposits.
- For every 4 grains of hardness, you will need 4-10% more product for the same degree of cleaning.
- Chemical applications must be done in a specific order.
- Directional nozzles must be placed correctly to maximize chemical coverage.
- Air and water pressure settings must be maintained.
- Time needs to be carefully balanced between, chemicals on surface, temperature and mechanical action.
- As dwell time increases (to a limit of diminishing returns), the cleaning power increases.
- Mechanical, plumbing and electrical systems needed to deliver optimal performance.
- Friction systems focus on cloth, brushes and bristles.
- Touchless systems focus on water pressure and volume.
