Cleaning and disinfecting are not the same job. You can wipe a worktop spotless and still leave it covered in bacteria, and you can disinfect a surface that still looks grubby. A good disinfectant spray kills the germs a normal cleaner leaves behind, on the worktops, taps and handles your hands touch most. These are the five we rate for 2026, picked from what is actually on UK shelves now.
We disinfect kitchens and bathrooms for a living, so we get through a lot of these. This guide is about the sprays and concentrates you use to kill germs, not general surface cleaners, and it covers a bleach-free everyday pick, a money-saving concentrate, a baby-and-food-safe option and a couple of plant-based sprays. The one thing nearly all of them share, and the thing most people get wrong, is contact time: the surface has to stay wet for about 5 minutes to actually disinfect. If you are working through the cupboard, our sibling guides to the best all-purpose cleaners and the best oven cleaners cover the cleaning side. And if a whole home needs sorting, our domestic cleaning and deep cleaning teams do this every day.

Dettol Antibacterial Surface Cleanser
The bleach-free spray we hand most people: cheap, trusted and proven on the bugs that matter.
| Form | Trigger spray, 750ml (also 500ml) |
|---|---|
| Kills | 99.9% of bacteria & viruses, incl. E. coli, MRSA, salmonella, flu, coronavirus and RSV |
| Surfaces | Kitchens, bathrooms, food surfaces, baby equipment, sealed hard surfaces |
| Scent / bleach | Original or Lime & Mint, bleach-free |
| How to use | Spray on, wipe with a clean damp cloth, no rinse needed |
| Price | About £2–£2.30 |
Reasons to buy
- Kills 99.9% of bacteria and viruses, with a long named list including MRSA, salmonella and coronavirus
- Bleach-free, so it is fine around children, pets and coloured fabrics
- Cleared for food contact surfaces, so it suits worktops and chopping boards
- In every supermarket, often around £2 on a Clubcard or Nectar price
Reasons to avoid
- Not suitable for windows, mirrors, painted or varnished surfaces
- The fragrance is light and does not linger like a Zoflora
If you only buy one disinfectant spray, buy this. Dettol is the brand most people already reach for, and the surface cleanser does the everyday job well: it kills 99.9% of bacteria and viruses, including the ones you actually worry about like MRSA, salmonella and coronavirus. You spray it straight on, wipe with a clean damp cloth, and there is no rinsing.
One honest note from doing this for a living. The label says spray and wipe, but for real disinfection you want the surface to stay wet for a short while before you wipe, not wiped dry on contact. It is bleach-free, so it will not bleach a tea towel or a dark worktop, which is half the reason we keep it on the van. It is not for glass or varnished wood.

Zoflora Concentrated Multipurpose Disinfectant
One small bottle makes about 10 litres of disinfectant, so it is the cheapest way to do the whole house.
| Form | Concentrate, 250ml (also 120ml, 500ml, 1L) |
|---|---|
| Kills | 99.9% of bacteria & viruses, incl. SARS-CoV-2, when diluted 1:40 |
| Surfaces | Most hard surfaces, floors, bins, drains; dilute for a trigger spray |
| Scent / bleach | Dozens of fragrances, scent lasts up to 24 hours, bleach-free |
| Contact time | Leave wet for 5 minutes before wiping |
| Price | About £2.89–£3.45 for 250ml |
Reasons to buy
- One 250ml bottle makes around 10 litres of disinfectant, so the cost per spray is tiny
- Kills 99.9% of bacteria and viruses including coronavirus at the 1:40 dilution
- The fragrance genuinely lasts, often a full day, which no ready-made spray here matches
- Bleach-free and made for floors, bins and drains as well as surfaces
Reasons to avoid
- You have to measure and mix it; a capful (10ml) to 400ml of water for a spray bottle
- Diluted disinfectant keeps its strength for about two weeks, so mix small batches
- Strong neat, so keep the concentrate away from pets until it is diluted and dry
Zoflora is the value pick by a distance. It is a concentrate, so you dilute one capful in 400ml of water for a trigger bottle, or 1 part to 40 in a bucket for floors. At that dilution it kills 99.9% of bacteria and viruses, including coronavirus, and a single 250ml bottle makes around 10 litres of usable disinfectant. That is dozens of refills for under £3.50.
The bit people love is the smell, which is perfumer-made and lasts up to 24 hours, so a kitchen still smells clean the next morning. The catch is contact time. Zoflora itself says leave it on for 5 minutes to actually disinfect, so spray the surface, leave it visibly wet, and wipe after. Mix it in small batches, because once diluted it holds its germ-killing strength for about two weeks.
Where to buy
Sold in 120ml, 250ml, 500ml and 1L through Tesco, Sainsbury’s, Morrisons, Wilko and Amazon. Affiliate links coming soon — price last checked May 2026.
Milton Antibacterial Surface Spray
Zero alcohol, zero bleach, food-safe and backed by named EN standards. The safe choice for nurseries.
| Form | Trigger spray, 500ml, 2-in-1 cleaner and disinfectant |
|---|---|
| Kills | 99.9% of germs; bacteria, yeasts and enveloped viruses incl. coronavirus |
| Standards | Tested to EN 1276, EN 13697, EN 1650 and EN 14476 |
| Surfaces | Highchairs, worktops, fridges, chopping boards, toys, potties; not marble or limestone |
| Scent / bleach | Light scent, 0% alcohol and bleach-free, lactic acid based |
| Contact time | Leave for 5 minutes |
Reasons to buy
- 0% alcohol and bleach-free, with a plant-based lactic acid formula
- Backed by named EN standards for bacteria, yeasts and viruses, which most home sprays do not quote
- Safe on food surfaces and baby equipment, and trusted by midwives for decades
- A genuine 2-in-1, so it cleans and disinfects in one step
Reasons to avoid
- Not for marble or limestone, so watch natural stone worktops
- A 500ml bottle is dearer per ml than the supermarket own-brands
- The 5-minute contact time is easy to forget if you are used to a quick wipe
If you want the reassurance of no alcohol and no bleach, Milton is the one. It has cleaned and disinfected baby bottles and equipment for over 70 years, and the surface spray carries that across to worktops, highchairs and toys. The formula is plant-based lactic acid, and unusually for a home spray it lists the actual EN standards it meets for bacteria, yeasts and viruses, including coronavirus.
It is a true 2-in-1, so you can clean and disinfect in one pass on most surfaces, and it is cleared for food contact areas. The thing to remember is the contact time: Milton says leave it on for 5 minutes, so spray, leave it wet, then wipe. Keep it off marble and limestone, where the mild acid can dull the finish.

Method Anti-Bac All-Purpose Cleaner
A plant-based spray that cleans and kills 99.9% of germs, and the only one here you will enjoy using.
| Form | Trigger spray, 828ml (refill pouches available) |
|---|---|
| Kills | 99.9% of household germs |
| Surfaces | Sealed counters, worktops, highchairs, door handles, bins |
| Scent / bleach | Peach Blossom and other scents, bleach-free |
| Active | Plant-based, lactic acid formula |
| Price | About £2.50–£4 for 828ml |
Reasons to buy
- Plant-based, bleach-free formula that kills 99.9% of household germs
- Big 828ml trigger bottle, with cheaper refill pouches to cut plastic
- Cleans and disinfects in one step on sealed hard surfaces
- The scents are genuinely pleasant, so people actually use it
Reasons to avoid
- It does not quote EN standards the way Milton and Astonish do
- Not a heavy-duty bathroom or mould product; it is an everyday all-rounder
- Scented, so less suitable if anyone is sensitive to fragrance
Method is the spray for people who hate the smell of disinfectant. The Anti-Bac All-Purpose Cleaner is plant-based and bleach-free, kills 99.9% of household germs, and comes in a big 828ml trigger bottle with refill pouches to save on plastic. The Peach Blossom scent is the popular one, and it is the rare cleaning product that makes a kitchen smell nice rather than clinical.
It cleans and disinfects sealed worktops, highchairs, handles and bins in one go, which makes it a good daily driver. It is lighter touch than the others here, so it is an everyday all-rounder rather than a deep bathroom or mould spray, and it does not publish the EN test numbers that Milton and Astonish do. If you want a spray you will reach for without holding your breath, this is it.
Where to buy
Sold through Ocado, Waitrose, Amazon and Method direct, with 2L refill pouches. Affiliate links coming soon — price last checked May 2026.
Astonish Disinfectant Spray (Zesty Lemon)
Vegan, virus-tested and often under £3. The cheap spray that still backs up its kill claims.
| Form | Trigger spray, 550ml (formerly Germ Clear) |
|---|---|
| Kills | 99.9% of bacteria & enveloped viruses, incl. coronavirus |
| Standards | BS EN 1276/13697 (bacteria); EN 14476:2013+A2:2019 (viruses) |
| Surfaces | Hard non-porous surfaces around the home; not food prep or baby utensils |
| Scent / bleach | Zesty Lemon (also Linen Fresh, Winter Spice), vegan, bleach-free |
| Contact time | Leave for 5 minutes |
Reasons to buy
- Cheap, often under £3, from a established Yorkshire cleaning brand
- Kills 99.9% of bacteria and enveloped viruses, tested to BS EN and EN 14476 standards
- Vegan, never tested on animals, and bleach-free
- Choice of scents, so it does not smell harshly chemical
Reasons to avoid
- Not for food preparation surfaces or baby utensils, unlike Dettol or Milton
- Pricing jumps around between retailers, from about £1.50 to £5
- Needs the full 5 minutes wet to hit the tested kill claims
Astonish is the budget pick that does not feel like a compromise. The ready-to-use Disinfectant Spray, which used to wear the Germ Clear name, kills 99.9% of bacteria and enveloped viruses including coronavirus, and it backs that with real testing: BS EN 1276 and 13697 for bacteria, and EN 14476 for viruses. It is vegan, bleach-free, and usually sits under £3.
Use it on hard non-porous surfaces around the home, but not on food preparation surfaces or baby utensils, which is where Dettol and Milton have the edge. Like the others, the kill claim depends on contact time, so leave it wet for 5 minutes before wiping. For a cheap spray to keep under the sink for general surfaces, it is hard to beat.
Where to buy
Sold through Wilko, Poundstretcher, B&M, Amazon and Astonish direct, in several scents. Affiliate links coming soon — price last checked May 2026.
How to choose a disinfectant spray
Most homes need one bleach-free spray for everyday surfaces and, if you disinfect a lot, a concentrate for the bigger jobs. Past that, three things decide which spray suits you.
Cleaner, disinfectant, or both?
A cleaner shifts dirt. A disinfectant kills germs. They are different jobs, and most sprays do one well. If a surface is greasy or visibly dirty, clean it first, because grime stops a disinfectant reaching the germs. A 2-in-1 like Milton or Method saves a step on lighter mess, but even then you let the disinfectant sit before wiping.
Bleach or bleach-free?
For everyday germs on worktops, taps and handles, bleach-free does the job without fumes, splash marks or risk to fabrics. Every spray on this list is bleach-free. Keep a bleach product for drains, white grout and mould, but for daily wiping around children, pets and food, bleach-free is the easier choice.
What the kill claims actually mean
That 99.9% figure is a lab result, measured against named bugs after a set contact time on a clean, wet surface. The European standards behind it are EN 1276 and EN 13697 for bacteria and EN 14476 for viruses, which Milton and Astonish both quote. A spray that names its standards has done the testing. A vague “kills germs naturally” claim with no standard has usually not.
Contact time: the bit everyone gets wrong
This is the practitioner note that matters most. The kill claim only holds if the product stays on the surface for the time the maker tested, which is 5 minutes on Zoflora, Milton and Astonish. Spray it, leave the surface visibly wet, do something else, then come back and wipe. Spraying and wiping straight off cleans the surface but barely disinfects it. On a busy worktop we spray, move to the next job, and wipe on the way back.
How to disinfect surfaces properly, step by step
- Clear and clean the surface first, so there is no grease or food in the way.
- Spray an even coat, enough to leave the whole surface visibly wet.
- Leave it for the contact time on the label, usually 5 minutes.
- Wipe with a clean cloth, or with kitchen roll on food surfaces, and let it dry.
- On food surfaces, follow the label; some sprays say rinse with clean water after.
Two small habits make the biggest difference. Use a clean cloth, because a dirty one just moves germs around, and do the high-touch spots daily: taps, handles, switches and the toilet flush. Everywhere else, weekly is plenty for a normal home.

Frequently asked questions
What is the best disinfectant spray in 2026?
For most homes the Dettol Antibacterial Surface Cleanser is the best disinfectant spray, because it kills 99.9% of bacteria and viruses, it is bleach-free and it is in every supermarket for about £2. If you want the cheapest way to disinfect the whole house, Zoflora concentrate works out far cheaper per spray. For nurseries, food surfaces and anyone who wants no alcohol or bleach, Milton is the safer pick.
What is the difference between a cleaner and a disinfectant?
A cleaner lifts dirt and grease off a surface. A disinfectant kills the germs left behind. They are not the same job, and most sprays only do one well. A few products, like Milton and Method, are sold as 2-in-1 cleaner-disinfectants, but even then you usually clean visible mess off first, then leave the disinfectant on long enough to work.
How long does disinfectant spray need to stay on the surface?
Longer than most people leave it. The kill claims on the label are measured after a set contact time, and on Zoflora, Milton and Astonish that time is 5 minutes. Spray it, then walk away and let the surface stay visibly wet for the full time before you wipe. Wipe it off after ten seconds and you have cleaned the surface, not disinfected it.
Do disinfectant sprays really kill 99.9% of germs?
They do, but only against the specific bugs and the contact time the maker tested. The 99.9% figure usually comes from European standards such as EN 1276 and EN 13697 for bacteria and EN 14476 for viruses, which is what Milton and Astonish quote. It is a lab result on a clean, wet surface for the stated time, not a promise that one quick squirt sterilises a greasy worktop.
Is a bleach-free disinfectant as good as a bleach one?
For everyday kitchen and bathroom germs, yes. Bleach-free sprays like Dettol, Milton and Method kill 99.9% of bacteria and viruses without the fumes, the splashback marks or the risk to coloured fabrics. Bleach still has its place for drains, white grout and mould stains, but for wiping down surfaces around children, pets and food, a bleach-free spray is the easier and safer choice.
Can I use disinfectant spray on food preparation surfaces?
Some, not all. Dettol and Milton are both cleared for food contact surfaces, so they suit chopping boards and worktops, though you should follow the label. Astonish’s ready-to-use spray specifically excludes food preparation surfaces and baby utensils. Always check the back of the bottle, and where in doubt rinse a food surface with clean water after the contact time.
Is concentrated disinfectant cheaper than a ready-made spray?
Much cheaper per use. One 250ml bottle of Zoflora concentrate makes around 10 litres of disinfectant at the 1:40 dilution, which is dozens of trigger-bottle refills for under £3.50. A ready-to-use spray is more convenient and there is no measuring, but if you disinfect a lot of surfaces, a concentrate is the cheapest way to do it.
How often should I disinfect surfaces at home?
Daily on the spots that get touched and dirty most: kitchen worktops, the hob area, taps, door handles, light switches and the toilet. Everywhere else, a weekly wipe-down is plenty for a normal home. Step it up when someone is ill, after handling raw meat, or if you have a new baby or a poorly pet in the house.
