Spray Nozzles for Cleaning

Engineering Consideration 1- Which level of cleaning is required?

When sourcing the correct spray solution the first question is what level of cleaning needs to be achieved. Cleaning can be roughly categorised into 5 levels :-

Sterilising.  The removal of residue by either washing or rinsing and the additional application of chemicals and/or heat that will kill all life.

Disinfecting.  The removal of residue by either washing or rinsing and the additional application of chemicals and/or heat that will kill 100% of bacteria but not necessarily spores.

Sanitising.  The removal of residue (either washing or rinsing) and the addition of a sanitising chemical that kills or removes contaminants or pathogens to an acceptable level.

Washing. The removal of residue by a combination of dissolving in cleaning fluid and action of direct pressure.

Rinsing. The removal of most or all of residue by dissolving in cleaning fluid alone.

After the level of required cleaning is determined consideration can be given to the impact, volume and time of spray that will be required to achieve this.
