Bright Nickel Cloudy Deposits is one of the recurring questions on finishing forums — and most first answers jump to a single fix. There isn’t one: the symptom has several causes, each confirmed differently.
Triage: symptom → confirm → first move
| Symptom | Likely root | Confirm by | First move |
|---|---|---|---|
| Uniform haze all over | Metallic contamination (Cu, Zn) | Hull cell: dull low-CD band | Dummy plate at low CD |
| Cloudy streaks that follow rack | Wetter shortage / surface tension | Stalgmometer reading | Titrate to 35–45 dyn/cm |
| Cloud with pinprick pits | Organics + gas | Hull cell banding | Carbon trial before dosing |
| Haze on castings only | Base metal drag-in (Zn) | By-alloy pattern | Segregate alloys; check strike |
| Haze after maintenance day | Work done: filter change, make-up | Revert one change | Restore and re-verify |
The routine
- Photograph the part before touching it — the pattern is evidence
- Confirm by the column: don’t treat before you know
- Run one corrective action only; verify before the next
- Log everything on the tank card
Safety: Safety: nickel baths are skin sensitisers and dummy plating runs live tanks unattended overnight — check flood, ventilation and lock-out before leaving.
