Flu Season Isn't Over: The 275°F Touch-Point Cleaning Checklist
Steam sanitization at 275°F kills 99.9% of flu and RSV viruses on high-touch surfaces without chemicals, protecting San Diego families all season.
Published: February 12, 2026
Why Is Touch-Point Cleaning Critical During Flu Season?
San Diego's mild winter doesn't mean flu season skips us. The CDC reports that flu activity peaks between December and March, with RSV (respiratory syncytial virus) adding a second wave of illness that hits children and older adults hardest.
The problem isn't airborne transmission alone. Up to 80% of infectious diseases spread through surface contact, according to public health research. Every doorknob, light switch, and faucet handle in your Poway or Scripps Ranch home becomes a potential transmission vector.
Most households focus on wiping down the kitchen counter and calling it done. But the average home contains over 300 high-touch surfaces that need regular sanitization during flu season. This guide gives you the complete room-by-room checklist and explains why 275°F steam sanitization outperforms spray-and-wipe disinfection.
How Long Do Flu Viruses Survive on Household Surfaces?
Influenza and RSV viruses don't die the moment someone leaves the room. The CDC's surface cleaning guidelines confirm that pathogens persist for hours to days depending on the material.
| Surface Type | Virus Survival Time |
|---|---|
| Doorknobs (brass/chrome) | Up to 24 hours |
| Stainless steel (fridge, faucets) | Up to 48 hours |
| Plastic (remotes, switches) | 24-48 hours |
| Glass (phones, tablets) | Up to 96 hours |
| Wood (railings, furniture) | Up to 24 hours |
| Fabric (upholstery, pillows) | 8-12 hours |
A sick child touches the refrigerator handle before school. That virus survives on the stainless steel for up to 48 hours. Every family member who opens that fridge picks up the pathogen. In neighborhoods like Hillcrest and North Park where open-plan living is common, contamination spreads from kitchen to living room through shared touch points within minutes.
How Does 275°F Steam Sanitization Work?
Thermal sanitization is the most effective chemical-free method for eliminating pathogens on household surfaces. Here is the science behind the heat.
Pressurized water vapor reaches 275°F, far exceeding the 212°F threshold needed to denature viral and bacterial proteins on contact.
Eliminates influenza, RSV, E. coli, salmonella, and dust mites. No chemical required, no residue left behind, no dwell time needed.
Pure water vapor leaves zero toxic film on countertops, handles, or toys. Safe for infants, pets, and chemically sensitive family members.
The EPA's disinfectant guidelines require spray products to remain wet on surfaces for 3 to 10 minutes to achieve the kill rates listed on the label. Most people spray and immediately wipe, reducing effectiveness by up to 90%.
Steam at 275°F kills on contact. There is no dwell time, no chance for user error, and no chemical residue for children or pets to encounter afterward. That is why we use commercial-grade Dupray Neat steam cleaners across every Poway, Scripps Ranch, and North Park home we service during flu season.
What Does a Complete Touch-Point Checklist Include?
Our room-by-room audit covers every surface your family touches daily. Use this checklist for DIY sanitization between professional visits, or let our team handle it with 275°F steam.

This checklist totals over 60 individual touch points across a typical San Diego home. During a standard cleaning, most homeowners address fewer than 15. That leaves 75% of germ hotspots untouched. Our deep cleaning service combined with steam sanitization covers every surface on this list.
How Often Should You Clean Touch Points During Flu Season?
Frequency depends on household size, whether anyone is currently sick, and the number of people entering and leaving your home daily.
Once daily + weekly pro cleaning
Wipe high-traffic touch points daily with EPA-registered wipes. Schedule weekly or bi-weekly professional cleaning with steam sanitization.
Every 4-6 hours + post-illness steam
Increase cleaning to 2-3 times daily in shared spaces. Isolate the sick person's bathroom. Book professional steam sanitization once illness passes.
Twice daily + bi-weekly pro cleaning
RSV hospitalizes thousands of children under 5 annually. Focus on surfaces below 3 feet: cabinet pulls, drawer handles, toy bins, and low light switches.
Twice daily + weekly steam
Adults over 65 face the highest flu hospitalization rates. Steam sanitization eliminates pathogens without chemicals that may interact with medications.
Is DIY Spray-and-Wipe Enough to Kill Flu Viruses?
Most households rely on disinfectant sprays or wipes during flu season. Here is how that approach compares to professional 275°F steam sanitization.
| Factor | DIY Spray & Wipe | 275°F Steam Sanitization |
|---|---|---|
| Contact time accuracy | Often wiped too quickly (needs 3-10 min wet) | 275°F steam kills on contact instantly |
| Chemical residue | Leaves disinfectant film on surfaces | Zero chemical residue with steam |
| Touch points covered | 10-15 obvious surfaces | 40-60+ surfaces per room |
| Child and pet safety | Toxic if ingested or inhaled | Chemical-free thermal sanitization |
| Effectiveness | Variable (depends on dwell time) | 99.9% kill rate at 275°F |
| Time required | 45-90 minutes per session | Included in professional visit |
- Daily wipe-down of the 10-15 most-touched surfaces
- Quick disinfection after a guest leaves
- Spot-cleaning when a child sneezes on a doorknob
- Maintaining surfaces between professional visits
- Someone in the household has been sick
- You have children under 5 or adults over 65
- Family members have chemical sensitivities
- Your home hasn’t had a deep sanitization in 3+ months
- You want to cover all 60+ touch points, not just 15
- You need CDC-level disinfection without toxic residue
DIY spray-and-wipe handles daily maintenance. But during peak flu and RSV season, professional steam sanitization covers the 75% of touch points most households miss. For families in Hillcrest, Scripps Ranch, and Poway, adding our $49 steam sanitization add-on to any regular cleaning or deep cleaning visit provides hospital-grade disinfection without harsh chemicals.

San Diego's dry winter air allows respiratory droplets to travel farther and survive longer on surfaces. Families in North Park and Hillcrest with children in daycare face compounded exposure -- kids bring pathogens home on hands and backpacks, contaminating touch points within minutes.
Which Rooms Should You Prioritize for Touch-Point Cleaning?
Not all rooms carry equal risk. Here is how to prioritize when time or budget is limited.
Highest touch frequency. Refrigerator handle alone is touched 20-30 times daily. Food prep creates cross-contamination risk.
Toilet flush levers and faucet handles harbor concentrated pathogen loads. Moisture accelerates bacterial growth.
First surfaces touched when entering the home. Doorknobs and stair railings transfer outdoor pathogens indoors.
Shared electronics and communal seating spread pathogens across every family member throughout the day.
Lower traffic than shared spaces, but nightstand surfaces and light switches need daily attention during illness.
Keyboards harbor more bacteria than toilet seats. Critical if shared or used after handling food.

Frequently Asked Questions
How long do flu viruses survive on household surfaces?
Influenza viruses survive up to 24 hours on hard, non-porous surfaces like doorknobs and light switches, and up to 48 hours on stainless steel surfaces like refrigerator handles and faucets. Soft surfaces like upholstery harbor viruses for shorter periods, typically 8-12 hours. The CDC recommends daily disinfection of high-touch surfaces during flu season to break transmission chains.
What is 275°F steam sanitization and how does it kill bacteria?
Steam sanitization uses pressurized water vapor heated to 275°F to kill 99.9% of bacteria, viruses, and dust mites on contact without chemicals. The extreme heat denatures proteins in pathogens, destroying their ability to reproduce. Bravo Maids uses commercial-grade Dupray Neat steam cleaners for touch-point sanitization across San Diego homes during flu and RSV season.
How often should I disinfect high-touch surfaces during flu season?
During active flu season, the CDC recommends disinfecting high-touch surfaces at least once daily in healthy households and multiple times daily if someone in your home is sick. High-priority surfaces include doorknobs, light switches, faucet handles, remote controls, and toilet flush levers. Professional steam sanitization every 1-2 weeks provides a deeper level of pathogen elimination.
Is steam cleaning better than spray disinfectants for killing flu viruses?
Steam cleaning at 275°F eliminates 99.9% of pathogens without chemical residue, making it safer for families with children, pets, or chemical sensitivities. Spray disinfectants require specific contact times (often 3-10 minutes of wet surface contact) to be effective, and most people wipe surfaces too quickly. Steam provides instant thermal kill on contact and leaves no toxic residue behind.
What are the most commonly missed touch points during cleaning?
The most overlooked touch points include cabinet pulls, appliance handles, stair railings, thermostat controls, alarm keypads, drawer pulls, garbage disposal switches, and charging station surfaces. Remote controls and gaming controllers are also frequently missed despite being handled by every household member. A professional touch-point cleaning checklist covers 40-60 surfaces per room.
