Car Cleaner Testing: Keep Product Quantity and Agitation Effort Separate

The key distinction

Decide whether the question concerns cleaning under a fixed effort or the complete effort needed to reach an agreed standard. Both can be useful, but they require different records. A fixed-pass test compares one controlled condition; a clean-to-standard test compares the practical work required. Do not switch between these interpretations after seeing the result.

Practical checks

1. Define the question and an acceptable, surface-appropriate agitation method before testing.
2. Record product quantity, contact process and agitation separately, including any additional work.
3. Inspect the final surface and report the result together with the effort used to obtain it.

Example

Illustrative example: cleaner A reaches the target after one permitted cleaning cycle, while cleaner B requires another. Reporting only that both areas became clean hides the workload difference. Conversely, claiming that A has superior chemistry from one uncontrolled demonstration would go beyond the evidence.

Scope and limits

Never increase pressure or use a more abrasive tool just to force a test area to pass. Stay within the surface and product instructions. If the required effort risks damaging the finish, stop and reassess the cleaning method and the nature of the remaining mark.
