How to clean your Alcolizer Technology Instruments

Regular maintenance of your Alcolizer instrument is essential for Accuracy, Functionality, and Longevity.

Using incorrect cleaning agents – especially those containing alcohol – can compromise your Alcolizer breathalyser. Alcohol-based cleaners may contaminate the fuel cell, leading to false readings, especially in passive and mouthpiece-based testing.

Risk of Alcohol-based Cleaners

- Fuel cell contamination
- False readings
- Leave residue that interferes with calibration
- Reduced instrument reliability

To Protect Your Instrument

- Avoid alcohol-based or harsh chemical cleaners
- Only use non-alcohol-based solutions

Cleaning Recommendations

- Wear appropriate PPE (e.g. gloves)
- Use a soft cloth and non-alcohol-based antibacterial spray or wipes.
- Gently wipe surfaces – avoid direct spraying.
- Do Not Use
  - Alcohol-based cleaners
  - Abrasive pads
  - Harsh chemicals
- Clean the body and screen daily or as needed based on usage and environment.
- Refer to your User Manual for model-specific instructions

If Alcohol-Based Cleaners Were Used

- Allow at least 15 minutes for evaporation before testing
- Avoid testing in the same location immediately after cleaning
- Ensure complete evaporation/drying before testing
- Perform a pre-zero test if supported by your instrument

Best Practices by Instrument Type

Wall-Mounted Breathalysers
- Use a new, clean straw for each test
- Dispose of straws immediately
- Clean the sample port as per the User Manual
Handheld Breathalysers
- Use a new, sealed mouthpiece for each test
- Dispose of mouthpieces after use
- Wear fresh gloves between tests
- Optional – Use spit-trap mouthpieces with non-return valves

Hand Hygiene

- Wash hands thoroughly after each test
- Use gloves when handling mouthpieces, straws, or cleaning instruments
