The Decontamination Cycle – Instrument Pre-Cleaning

The decontamination cycle is the process used to ensure reusable dental instruments are safe for use on subsequent patients.

The safe transportation of instruments from the dental surgery to the decontamination room is the first part of this process. This article focuses on pre-cleaning, an important component of the instrument transportation process.

What is Instrument Pre-Cleaning?

Instrument pre-cleaning is a supporting step to aid in the decontamination of reusable instruments. 

Ideally, instruments should be cleaned and processed immediately after use. However, since this is not always feasible, pre-cleaning helps bridge the gap and supports effective decontamination. The HTM01-05 recommends the use of pre-cleaners if delays in reprocessing are unavoidable.

"Instruments cleaned as soon as possible after use may be more easily cleaned than those left for a number of hours before reprocessing. Where this is not possible, water immersion or the use of a foam spray or gel intended to maintain a moist or humid environment are thought useful in aiding subsequent decontamination"

The primary function of a pre-cleaner is to keep soils moist and prevent them from drying onto instrument surfaces. Dried soils are significantly harder to remove, can damage instrument surfaces and coatings, and block the hinges and joints of instruments — reducing their functionality and lifespan.

A good pre-cleaner should initiate the cleaning process itself, loosening and breaking down organic soils so they are easier to remove during the subsequent manual or mechanical cleaning stage.

Instruments can also be immersed in water as a basic pre-soak, but extended wet storage should be avoided — prolonged immersion increases the risk of microbial growth.

Gel Pre-Cleaner

Pre-Klenz

A ready-to-use enzyme-free gel pre-cleaner. The clear gel formulation means soiled sharps remain visible during transport — a key safety advantage over opaque alternatives.

Humid Transport Pouch

InstruPak — Humid Transport Pouches

An alternative to pre-treatment gels and sprays. Place instruments or cassettes into the pouch, add 20ml of water, and seal — creating a moist humid environment that prevents instruments from drying out prior to reprocessing.

✓ No chemical application required
✓ Prevents protein formation on instrument surfaces
✓ Maintains moist environment for up to 7 days

Pre-cleaning is a vital step in the decontamination cycle, ensuring that soils remain manageable, instruments are protected from damage, and the subsequent cleaning process is as effective as possible. Where there is any delay between instrument use and formal reprocessing — HTM01-05 is clear that a pre-cleaner should be used. With options available in gel, foam and humid pouch format, there is a product to suit every practice workflow.
