What Is Lysol Disinfectant Spray?
Lysol Disinfectant Spray is an aerosol disinfectant made by Reckitt Benckiser. It has been a household staple since the 1950s and is one of the best-selling cleaning products on Amazon. The spray works by releasing a fine mist of disinfecting chemicals that cling to surfaces and kill harmful microorganisms on contact.
It comes in several scents including Crisp Linen, Spring Waterfall, and Original. Each variant has the same disinfecting power — the scent is purely a personal preference.

What You Need Before You Start
Before you grab the can, make sure you have everything ready:
- Lysol Disinfectant Spray (any scent)
- Paper towels or clean microfiber cloth (for wiping if needed)
- Rubber gloves (recommended for sensitive skin)
- Good ventilation — open a window or turn on a fan
⚠️ Safety First Always read the product label before use. Keep out of reach of children and pets. Do not spray near open flames — the product is flammable. Avoid inhaling the mist directly.
How To Use Lysol Disinfectant Spray — Step by Step
Follow these steps carefully to get the best disinfecting results:
Step 1: Clean the Surface First
Lysol Disinfectant Spray is a disinfectant — not a cleaner. This is the most important distinction most people miss. If the surface has visible dirt, grease, or grime, you must clean it first before Disinfecting Wipes.
Use a damp cloth with dish soap or an all-purpose cleaner to wipe away any visible mess. Rinse and let the surface dry slightly. Now it is ready for Lysol.
💡 Pro Tip Disinfectants cannot penetrate through layers of dirt and grease. If you skip this step, the Lysol spray will not be able to reach and kill the germs underneath. Always clean first, then disinfect.
Step 2: Hold the Can Correctly
Shake the Lysol can gently. Hold it upright, about 6 to 8 inches (15 to 20 cm) away from the surface. Tilting the can too much can cause the spray to sputter or release in an uneven stream.
Step 3: Apply the Spray Evenly
Press the nozzle and apply a thin, even coat of spray across the entire surface. You want the surface to look visibly wet — but not dripping. A light, even mist is all you need. Move the can in a slow sweeping motion to cover the full area.
For large flat surfaces like kitchen counters or bathroom sinks, work from one end to the other in a straight line. For small or irregular surfaces like door knobs and light switches, hold the can closer and spray in a short burst.
Step 4: Let It Sit for the Full Contact Time
This is the step that 90% of people skip — and it completely ruins the effectiveness of the disinfectant. The surface must remain visibly wet for the full contact time listed on the label.
- Bacteria (like E. coli, Salmonella): 10 minutes contact time
- Viruses (like Influenza A, SARS-CoV-2): 10 minutes contact time
- Fungi (like Trichophyton, Candida): 10 minutes contact time
Do not wipe the surface before the contact time is complete. Just leave it alone and let the product do its job.
⏱️ Timer Tip Set a 10-minute timer on your phone right after spraying. It sounds simple, but most people wipe the surface after 30 seconds. That short contact time is NOT enough to kill most germs.
Step 5: Wipe or Air Dry
After the full contact time has passed, you have two options:
- Air dry: Simply let the surface dry on its own. No wiping needed. This is the easiest approach for surfaces like trash cans, toilet lids, or gym equipment.
- Wipe with paper towel: For surfaces where you don’t want any residue (like kitchen counters), wipe gently with a clean paper towel after the 10 minutes are up.
Do not rinse the surface with water unless the product label specifically instructs it — rinsing removes the disinfectant before it finishes working.
Step 6: Wash Your Hands
After using any disinfecting product, always wash your hands with soap and water for at least 20 seconds. Even if you wore gloves, it’s a good habit to maintain.

10 Pro Tips for Getting the Best Results
- Always clean surfaces before disinfecting — dirt blocks the active ingredients.
- Use in a well-ventilated room. Open windows or run an exhaust fan.
- For the bathroom, spray the toilet area last to avoid cross-contamination.
- Spray door knobs every day during cold and flu season.
- Use separate cloths for kitchen and bathroom surfaces.
- For phones and tablets, spray a microfiber cloth — never spray electronics directly.
- Store the can at room temperature — extreme cold or heat affects performance.
- Buy multi-packs on Amazon for significant savings (often 20–30% off).
- For sick room disinfection, spray all surfaces and allow extra ventilation for 30 minutes.
- Check the expiry date — Lysol spray loses potency after the best-before date.
How Often Should You Use Lysol Disinfectant Spray?
The frequency depends on your household situation:
- High-touch surfaces (door knobs, light switches, remotes): Daily, or every other day during flu season
- Kitchen counters: After every meal prep involving raw meat or poultry
- Bathroom surfaces: 2 to 3 times per week
- Soft surfaces (mattresses, sofas): Once per week or after illness
- Sick room (when someone is ill): After every time the sick person leaves the room
You do not need to disinfect every surface in your home every day. Focus on high-touch, high-risk areas. Over-use of disinfectants can lead to surface damage and contribute to chemical resistance over time.
Frequently Asked Questions (FAQ)
Q1: Can I use Lysol spray directly on my hands or skin?
No. Lysol Disinfectant Spray is for surfaces only. It should never be applied to skin, eyes, or any part of the body. For hand sanitizing, use an alcohol-based hand sanitizer or wash your hands with soap and water.
Q2: Is Lysol spray safe to use around babies and toddlers?
After the spray has fully dried (usually 10 to 15 minutes), the surface is safe for children to touch. Do not allow children in the room while you are spraying. For baby cribs, high chairs, and toys, spray, wait 10 minutes, then wipe with a damp cloth and allow to air dry before your child uses the item.
Q3: Can I use Lysol spray on my phone?
Yes, but never spray it directly on your phone screen. Spray a small amount onto a microfiber cloth, then gently wipe the phone surface. Allow to air dry. For Apple products, Apple themselves have approved the use of Lysol wipes (not spray) on iPhone screens.
Q4: How long does Lysol spray remain effective after application?
Once the surface dries, the disinfecting action is complete. Lysol spray does not provide ongoing protection after it dries. If someone touches a disinfected surface, it can become contaminated again immediately. That’s why regular disinfection of high-touch areas is important.
Q5: Can I use Lysol spray on carpet or rugs?
Yes, Lysol can be used on carpet and rugs to deodorize and kill surface-level germs. Hold the can 6 to 8 inches away and apply a light mist. Do not saturate the carpet. Allow to air dry completely — this may take 30 to 60 minutes depending on how much you applied.
Q6: Is Lysol Disinfectant Spray effective against COVID-19?
. Lysol Disinfectant Spray is on the EPA’s List N — products approved for use against SARS-CoV-2 (the virus that causes COVID-19). It has been tested and confirmed to kill the virus in the 10-minute contact time as directed on the label.
Q7: What is the difference between Lysol spray and Lysol wipes?
Both products kill 99.9% of germs. Lysol wipes are more convenient for quick wipe-downs and are pre-moistened. The spray is better for large surfaces, fabrics, and hard-to-reach areas. For best results, use the spray for disinfecting and wipes for daily quick cleaning.
Final Thoughts
Lysol Disinfectant Spray is one of the most effective, affordable, and easy-to-use disinfectants available today. When used correctly — clean surface first, spray evenly, wait the full 10 minutes — it delivers on its promise of killing 99.9% of harmful germs.
The key takeaway from this guide is the contact time. Spray and wait. Most people spray and immediately wipe — that single mistake makes the product significantly less effective. Take the extra 10 minutes, and you’ll have genuinely disinfected surfaces in your home.
