Cold and flu season hits Portland offices hard. One person on your team calls in sick on Monday. By Friday, three more are home. You want a fix. You hear about electrostatic spraying. Someone on LinkedIn says it covers every surface in the room. You wonder: is that real, or is it a sales pitch?

Here is the truth. Electrostatic spraying is a tool. It does one thing well. It charges the disinfectant mist so the droplets wrap around surfaces. The back of a chair leg. The side of a monitor. The underside of a desk. A regular spray bottle leaves those spots dry. An electrostatic sprayer does not.

What it does not do is replace the regular clean. It does not scrub grout. It does not pull grease off a kitchen counter. It does not empty trash cans or restock soap. The clean has to happen first. The spray comes after.

When electrostatic spraying helps in a Portland office

After a confirmed flu or COVID case at the office
During winter cold and flu season (November through March)
For high-touch surfaces that wipes miss — door handles, light switches, phone receivers
For shared equipment in meeting rooms and break rooms
After any office event where a lot of people touched the same surfaces in one night

When it does not help

For dust, crumbs, or trash on the floor
For sticky counters or coffee stains
For restroom odor (you need a real restroom clean)
For windows, baseboards, or floor care
As a stand-alone service with no clean behind it

What to ask a Portland janitorial vendor before you pay for it

Any vendor can buy a sprayer. Not every vendor uses it the right way. Here is what to ask before you sign.

What product do you spray, and how long does it need to sit? Most EPA-registered disinfectants need 3 to 10 minutes of wet contact. If the vendor sprays and wipes in 30 seconds, the kill claim is empty.
Is the team trained on the equipment? A bad sprayer setting puts too much product in the air. That is wasteful, and it can irritate lungs.
Do you clean first, then spray? Disinfectant does not work through dirt. The base clean has to come first.
How often do you spray? A one-time spray after a sick day is fine. A weekly spray on top of your base clean is the right call during flu season.
What does the log look like? You want a sheet that shows the date, the room, the product, and the dwell time. That sheet is your proof if an employee asks.

How Strong Tower runs office disinfection in Portland

We have been cleaning Portland offices for 13 years. We are women-owned and fully insured. We do this for a living.

For most offices, we run a 5-night-a-week clean. Kitchens, restrooms, floors, trash, restock. That is the base. In winter, we add an electrostatic pass to high-touch zones one or two nights a week. The cost runs a few hundred dollars a month on top of your base service. We bring our own EPA-registered product. We bring our own sprayer. We leave a log.

For offices that have had a confirmed case, we run a one-time deep disinfection. We clean first, then we spray. The job takes about 90 minutes for a 5,000 square foot office.

If you are in Portland and want to talk through what your office needs, give us a call. If you are in Beaverton or Tigard, same deal. We also serve Lake Oswego and the rest of the metro. 📞 971 516 0787 | services.strongtowercs.com

The bottom line: electrostatic spraying is a good add-on during cold and flu season. It is not a magic wand. Pair it with a real base clean and your team walks into a safer space each morning.
