Conserve time and money, and take the best approach to precision cleaning the first time. While debris like finger oil or test dust may not present much of a challenge, cleaning processes for field applications may vary widely and must be effective on a range of contaminants and debris.
Dry Cleaning: Often performed with a swab or probe, this method may prove effective on oily contamination but tends to move – rather than remove – contamination. This process should be performed with video inspection to validate success, in a straight-line motion to move debris away from the initial point of contact.
Wet or Wet-to-Dry Cleaning: Commonly performed using a pre-saturated wipe, this method has the potential to flood the connector and thus draw up contamination from around the ferrule. Saturation must be carefully controlled to avoid failure.
Combination Cleaning: This is the recommended method to ensure maximum effectiveness and repeatability, and includes a minimal amount of precision solvent combined with no-lint, highly absorbent wiping media. With an integrated drying step built into the procedure, the simple process results in debris and contamination removal for first time cleaning.
