Car-Wash Product Consumption: Count Overspray Separately from Surface Coverage

The key distinction

Map where the product goes during a normal application. Some loss may be inherent to the approved method, while poor positioning or an unsuitable spray pattern may create unnecessary waste. Do not reduce the applied amount below the product's requirements simply to improve a consumption metric. The finished cleaning result remains part of the assessment.

Practical checks

1. Measure total product use for a defined task with a consistent starting setup.
2. Observe spray placement, runoff and inaccessible areas without introducing unsafe collection methods.
3. Trial a permitted adjustment to technique or equipment, then compare both consumption and the accepted final result.

Example

Illustrative example: two operators use the same approved cleaner on comparable vehicles. One sprays repeatedly from too far away and coats adjacent areas unnecessarily. Reviewing application technique may explain the difference more directly than changing the dilution or blaming the product.

Scope and limits

Consumption data does not establish airborne exposure, environmental compliance or surface compatibility. Those questions require the relevant product and workplace guidance. Use the measurement to improve a defined process, and retain any necessary application and removal steps even if they consume material.
