Water Spots, Film and Streaks After Finishing: Condition, First Check and Direction
This page reproduces the published diagnosis table for water spots, film and streaks after finishing: the observed condition, the useful first check and the possible direction. These are diagnostic steps to try, not a correction recipe, and a possible direction is a hypothesis rather than a confirmed cause. No water mineral specification, temperature, contact time, drying time or concentration is stated, implied or supplied.

Observed condition, useful first check and possible direction
| observed condition | useful first check | possible direction |
|---|---|---|
| Round spots with visible edges | Compare normal water with known low-mineral rinse water | Mineral concentration as droplets evaporate |
| Uniform chalky or milky film | Wipe a dried reference area and inspect rinse clarity | Compound carryover, suspended solids, or insufficient rinsing |
| Streaks running from holes or recesses | Observe drainage orientation and liquid trapped in features | Slow drainage or contaminated liquid leaving cavities during drying |
| Dark or colored staining | Check chemistry, mixed-metal contamination, time delay, and corrosion history | Chemical reaction or contamination; specialist review may be required |
| Fine haze that does not wipe away | Inspect under magnification before and after finishing | Micro-scratching or surface texture rather than removable residue |
The first checks the article asks for
These rows are about what the rinse water and the drying step leave behind. They name first checks rather than corrections: compare against a known low-mineral rinse water, inspect a dried reference area, and observe where liquid drains from.

Frequently asked questions
Does this tell me how to correct the water spots?
No. It gives first checks and possible directions to test. A direction is a hypothesis, not a confirmed cause, and the correction depends on which cause you actually find.
Can a longer rinse fix streaks?
Not necessarily. A streak from a hole usually means liquid was trapped and drained slowly during drying, which is a drainage question rather than a rinse-duration question.
Does it diagnose my part?
No. A condition lists a likely direction and a first check. The same mark can have more than one cause, and confirming it needs a controlled comparison.
Does it state cycle time, speed or temperature?
No. No cycle time, speed, amplitude, load ratio, concentration, temperature or removal result is stated or implied anywhere on this page or in its download.
Are the tables quoted exactly?
Yes. Every cell is taken from a single source table cell and verified against the captured page, including wording and punctuation.
