Products with documented SDS

Disinfectant only works if it is used the way the label says.

Most disinfection in commercial buildings fails for the same three reasons: the surface was never cleaned first, the product was wiped off before its dwell time elapsed, and the wrong product was chosen for the pathogen in question. Spraying a counter and immediately drying it is a cosmetic act. Soil shields microorganisms from contact, and every EPA-registered disinfectant carries a required wet contact time — often several minutes — that determines whether the claim on the label actually applies.

Cascade Clean Group runs disinfection as a documented procedure. We clean first, then disinfect with an EPA-registered product selected for the surface and the risk, hold the labeled dwell time, and work in a defined sequence so cross-contamination does not travel on the cloth. Color-coded microfiber separates restroom, kitchen, and general areas. Electrostatic and fogging application covers complex surfaces and large rooms efficiently, then targeted manual wiping handles the high-touch points that decide transmission — door hardware, switches, shared keyboards, phones, elevator buttons, badge readers, appliance handles, railings, and restroom fixtures.

We serve offices, medical and dental practices, schools and childcare, gyms, and shared workplaces across Seattle, Bellevue, Tacoma and the surrounding cities, with both scheduled programs and rapid outbreak response. Product safety data sheets are on file for anything used in your building, and your account manager answers in about 11 minutes when a confirmed case sends you looking for same-day service.

Why businesses switch

Why our disinfection actually meets the label claim

01

Clean first, then disinfect — with the dwell time held

Cleaning removes soil and organic load; disinfection kills what remains. Skip the first step and the second one does not work. Our technicians follow a two-stage procedure, hold each product's labeled wet contact time before any wiping or drying, and work in a set high-to-low, clean-to-dirty sequence with color-coded microfiber so a restroom cloth never touches a breakroom counter. That procedure, not the brand of spray, is what determines the outcome.

02

EPA-registered products matched to the environment

Quaternary ammonium, hydrogen peroxide, and hypochlorous chemistries all have different kill claims, dwell times, material compatibility, and odor profiles. Clinics, childcare centers, food-adjacent areas, and gyms each need different selections, and electronics and soft surfaces need products that will not damage them. We keep safety data sheets on file for every product used in your building and can provide the registration and dwell-time documentation your compliance officer or licensing inspector will ask for.

03

Scheduled programs and same-day outbreak response

Most clients run disinfection as a recurring layer inside their janitorial scope — high-touch points every visit, broader electrostatic treatment on a set interval. When something changes, we mobilize: a confirmed influenza, norovirus, RSV, or COVID case, a classroom outbreak, a gym locker-room issue, or an inspection tomorrow morning. Average response to a client message is 11 minutes, and we can usually be on site the same day or overnight to treat the affected zones before you reopen.

How often should disinfection happen?

Disinfection frequency is driven by occupancy, how many people touch the same surfaces, and how much regulatory exposure you carry. These are the programs we build most often in Puget Sound facilities.
