Cleaning of springs
From technical cleanliness to biological compatibility
Cleaning of springs
Processes
- Immersion
- Swiveling
- (Pressure) flooding
- Ultrasound
- Spraying
- Single tank process
- Drying
- Disinfection
Cleaning requirements
- De-oiling, degreasing
- Number and size of particles
- Reduction of colony forming units (CFU)
- Biological compatibility

The effect of liquid cleaning processes is essentially determined by the solvent power of the cleaning agents used and by the process applied.
Impurities must be dissolved and removed.
To do this, we use
- Chlorinated hydrocarbons
- Hydrocarbons
- Aqueous media
Technical cleanliness down to the lowest level is set out in VDA 19 Volume 19, and we can fulfil these conditions. We do of course also make allowance for customer-specific requirements. With effective cleaning processes and the subsequent packaging processes, we systematically minimize contamination risks.
Evidence can be provided by
- Residual dirt analysis as per VDA Volume 19
- Visual inspection (microscope)
- Determination of CFU
- Biological assessment
We make use of internal, external or accredited laboratories.
