ABB Circuit & Edge Connector Cleaning Guidelines
We have got Symphony Harmony system at our power plant. ABB Circuit & Edge Connector Cleaning Guidelines recommend to use Isopropyl alcohol, 99.5 percent electronic grade using cloth. We are planning to perform the cards cleaning during upcoming plant outage as they are full of dust.
1. Has anyone got any experience with such activity?
2. Any recommendations to get 100% results while avoiding any failure?

Isopropyl with ~100% is a common method to clean the connectors or the copper edges on the PCB
Please no synthetic here !
There is normally no need to clean the connector pins itself
For the whole PCB clean, waterfree gas
i.e.

A (very) thin layer of dust can reside on the PCB
Avoid to clean the whole PCB with Isopropyl, the dust will creep under the SMT devices
Also check also your PCB protection, i.e with a bracelet.
