Office Sanitization of High-Touch Surfaces

High-Touch Surfaces Are the Transmission Highways

In a typical Jacksonville office, there are 50-100 high-touch surfaces that multiple people contact throughout the day. A study published in the Journal of Occupational and Environmental Medicine found that improving high-touch surface hygiene in offices reduces the spread of viral infections by 30-40%.

These surfaces — doorknobs, light switches, shared equipment, and break room fixtures — are the highways on which pathogens travel from person to person.

At Clean Fix Jax, our office sanitization program prioritizes high-touch surfaces based on contact frequency and pathogen risk. Here's the complete guide to high-touch surface sanitization for your Jacksonville office.

The High-Touch Surface Hierarchy

Not all high-touch surfaces carry equal risk. Here they are ranked by contact frequency and transmission risk:

Very High Risk (Contact 50+ times per day)

• Main entrance door handles and push plates
• Elevator call buttons and interior buttons
• Restroom door handles and faucet handles
• Break room refrigerator handle and microwave buttons
• Shared phone handsets (if still in use)
• Printer and copier control panels

High Risk (Contact 20-50 times per day)

• Office suite door handles
• Light switches in common areas
• Conference room door handles and table surfaces
• Water fountain and bottle fill buttons
• Vending machine buttons
• Mail and package room handles

Moderate Risk (Contact 5-20 times per day)

• Individual office doorknobs
• Desk surfaces (shared workstations)
• Chair armrests in common areas
• Stair handrails
• Window blinds and shades

Proper Sanitization Technique

Sanitization effectiveness depends on technique, not just product strength:

The Clean-Then-Sanitize Method

Sanitizers and disinfectants are inactivated by organic matter. You must clean before sanitizing:

• Step 1 - Clean: Wipe the surface with a general-purpose cleaner to remove visible soil, oils, and debris. Use a clean microfiber cloth.
• Step 2 - Sanitize: Apply an EPA-registered sanitizer or disinfectant. Spray the surface until visibly wet.
• Step 3 - Wait: Allow the product to remain wet on the surface for the full contact time listed on the label (typically 3-10 minutes). This is the most commonly skipped step and the most important.
• Step 4 - Wipe (if required): Some products require wiping after the contact time. Others are no-rinse. Check the product label.

Surface-Specific Sanitization Protocols

Door Handles and Push Plates

• Clean with an all-purpose wipe, then apply disinfectant spray
• Allow full contact time
• Wipe both sides of the handle and the surrounding plate
• Frequency: Every 2 hours for main entrance, twice daily for interior doors

Shared Electronics

• Turn off and unplug equipment before cleaning
• Use alcohol-based wipes (70% isopropyl) on keyboards, mice, and phone handsets
• Never spray liquid directly onto electronics — apply to a cloth first
• Pay attention to the space between keys on shared keyboards
• Frequency: Daily, or between users on shared workstations

Break Room Surfaces

• Clean tables and countertops with dish soap first to remove food residue
• Apply food-safe sanitizer (hydrogen peroxide-based or quat-based at proper concentration)
• Sanitize the refrigerator handle, microwave handle and buttons, and coffee maker surfaces
• Frequency: After each use for tables, twice daily for appliance handles

Restroom Fixtures

• Apply disinfectant to all fixtures — faucet handles, flush handles, stall locks, and door handles
• Allow full contact time before wiping
• Use color-coded microfiber (red for toilets, yellow for sinks) to prevent cross-contamination
• Frequency: Twice daily minimum, more often in high-traffic restrooms

Jacksonville-Specific Considerations

• Humidity and bacterial growth: Jacksonville's humidity accelerates bacterial growth on surfaces. Moist surfaces like faucet handles and refrigerator handles support bacterial survival 3-5 times longer than in drier climates. Increase sanitization frequency for these surfaces.
• Pollen season: During spring, door handles and push plates accumulate a yellow pollen residue. Wipe more frequently to prevent the pollen film from becoming a bacterial growth medium.
• Storm season: After hurricanes or tropical storms, increase sanitization frequency throughout the office. Power outages affect HVAC and humidity control, which increases surface contamination.

Building a High-Touch Surface Map

Create a visual map of your office's high-touch surfaces to ensure consistent sanitization:

• Walk through the office and mark every surface that's touched by multiple people throughout the day
• Rank each surface by contact frequency: very high (50+ contacts/day), high (20-50), and moderate (5-20)
• Assign sanitization frequency based on risk level: very high risk surfaces every 2 hours, high risk twice daily, moderate risk daily
• Post the map in the cleaning supply area so all staff know which surfaces require attention
• Update the map quarterly or whenever office layout changes occur
