The water wash method is popular because it is typically less expensive than post-emulsifiable and the process time is faster since there are fewer processing steps.
Water washable penetrants (Method A) are available as Fluorescent (Type 1) or Visible (Type 2) penetrants and in multiple sensitivity levels for fluorescent penetrants.
Water washable penetrants work best on rough surface parts, threaded or grooved parts and parts with holes and orifices. Water washable penetrants are suitable for automated penetrant systems, large parts, and leak testing.
Water washable penetrants are removed by manual or automated water spray, manual wipe or air agitated immersion wash. If a manual spray is used the water pressure should not exceed 40 psi; the temperature should be between 50–100°F / 10–38°C using a coarse spray at a minimum distance of 12 in / 30 cm from the part.
Although water washable processing has its advantages, certain specifications will restrict its use because over-washing can occur in shallow discontinuities, which makes rinsing time critical to the process.
Advantages of water washable penetrants
- Lower cost (no emulsifier needed)
- Fewer processing steps
- Process time reduced
- Variables associated with emulsifier dwell time eliminated
Disadvantages of water washable penetrants
- Over washing can occur in shallow defects
- Water rinsing time is critical
- Water contamination of the penetrant is possible
