Working Solution or Concentrate: Label the Sample Sent for Cleaner Testing

A cleaner test report must identify whether the sample was tested as supplied or at a working dilution. Without that information, the result may be applied to a condition the laboratory never evaluated.

The key distinction

The distinction affects interpretation of measurements and compatibility observations. A concentrate can have different properties from the solution used on a vehicle. The laboratory request should therefore state the intended question and preparation method rather than leaving dilution to an undocumented assumption.

Practical checks

  1. Identify the exact product and supplied form.
  2. Specify the approved dilution and preparation water when testing the use condition.
  3. Require the report to retain the sample preparation and exposure details.

Example

Illustrative example: a supplier provides a measurement from the concentrate, while a workshop records observations from a diluted spray bottle. The two records should not be merged into one comparison without explaining the different sample states. A targeted test should reproduce the condition relevant to the customer's question.

Scope and limits

Do not infer that a concentrate is safe for direct use because a diluted sample performed acceptably. Equally, a concentrate result does not automatically describe the working solution. Product instructions govern application, and any compatibility claim must match the tested concentration and exposure.
