what is the correct order for treating surfaces with antimicrobial pesticides?
The correct order is: clean first, then sanitize or disinfect.
Quick Scoop: Why this order matters
- Step 1 – Clean: Remove visible dirt, food, grease, and other organic matter with a general cleaner and wiping or scrubbing. This exposes the microbes so chemicals can reach them.
- Step 2 – Sanitize or disinfect:
- Sanitize to reduce the number of microorganisms to a safe level (common in food-contact areas).
- Disinfect to kill most disease‑causing microorganisms on non‑food surfaces (e.g., bathrooms, high‑touch surfaces).
If you sanitize or disinfect before cleaning, dirt and organic material can block the antimicrobial pesticide, making it much less effective.
Simple example
Imagine a kitchen counter after raw chicken prep:
- Clean: Wipe with detergent and water to remove food residue and grease.
- Sanitize or disinfect: Apply the antimicrobial product, keep the surface wet for the full contact time on the label, then follow any rinsing directions.
So if you ever see multiple-choice options like:
- Sanitize, clean, disinfect
- Disinfect, clean, sanitize
- Clean first, then sanitize or disinfect
- There is no specific order required
The correct choice is: Clean first, then sanitize or disinfect.
