Disinfectants and Sanitisers: Milton, Dettol and Food-Safe Choices
Disinfectants kill a high proportion of germs on a surface. Sanitisers reduce bacteria to a safe level and suit food-contact areas. Many trade products clean and sanitise in one. Whichever you pick, the contact time on the label is what makes it work, so leave the surface wet for the stated time before wiping.
What is the difference between a disinfectant and a sanitiser?
A sanitiser reduces bacteria on a surface to a level treated as safe, which is why it is the usual choice on food-contact surfaces. A disinfectant kills a higher proportion of germs and is used where you need stronger control, such as washrooms, bins and after a spill. Plenty of trade products do both.
The words get used loosely on retail packaging, so read the label rather than the brand name. A bottle that says "cleaner sanitiser" is built to lift dirt and cut bacteria in one pass. A bottle that says "disinfectant" is built for germ control and may not shift grease at all. If a surface is visibly dirty, clean it first. Disinfectant sprayed onto grease or food debris cannot reach the surface underneath, so it does very little.
That two-step habit, clean then disinfect, is the single biggest difference between a kitchen that passes an inspection and one that does not. The wider chemical kit is set out in the commercial cleaning chemicals guide.
What is Milton used for in a business?
Milton is a chlorine-based sterilising fluid, best known for baby feeding equipment and for soaking small items. In a business it suits soaking jobs: utensils, chopping boards, cloths and food-prep bits that can sit in a solution. It is a soaking product first, not a general surface spray.
Because it is chlorine-based, treat it the way you treat bleach. Keep it away from acidic and ammonia-based cleaners, never mix it with anything, and store it in its own labelled container. Mixed chemicals can release toxic gas, which is why the rule is one product at a time with a rinse in between.
Check the label for whether a rinse is needed at the dilution you are using, and for how long items should stay in the solution. Soaking times and strengths vary by product, so the bottle in your hand is the authority, not a rule of thumb from a previous job.
Is Dettol spray good enough for a commercial kitchen?
Dettol spray is a familiar household disinfectant and works fine for general surfaces, bins, handles and washroom areas. For food-contact surfaces, check that the product you buy is stated as suitable for those surfaces and follow its rinsing instructions. Many kitchens use a dedicated food-safe cleaner sanitiser instead.
The practical issue with household brands in a busy business is cost per use, not performance. Retail-sized trigger bottles get expensive fast when you are cleaning down three times a day. Trade concentrates diluted into your own colour-coded trigger bottles bring the price per spray down a long way, and you carry less packaging.
What makes a disinfectant food-safe?
A food-safe disinfectant or sanitiser is approved for use on surfaces that touch food, typically meeting a standard such as BS EN 1276. Used and rinsed as the label directs, it controls bacteria without leaving harmful residue. In any food area, check for that approval before the product goes on the shelf.
Two habits keep food areas honest:
- Buy for the area, not the price. One food-safe product for prep surfaces, a separate stronger one for washrooms and bins.
- Colour-code the bottles. The same red, yellow, green and blue system used for cloths and mops, so a washroom spray never lands on a prep bench.
How long do you leave a disinfectant on a surface?
Leave it for the contact time printed on the label, with the surface staying visibly wet for that whole period. Spraying and wiping straight away is the most common mistake in any kitchen. The product needs time in contact with the surface to do the work it claims on the bottle.
Set the routine up so the wait costs you nothing. Spray a run of surfaces, move on to another job, then come back and wipe them down in the same order. Staff stop resenting the wait when it is built into the sequence rather than standing time.
Which product goes where?
| Area | What to use | Watch for |
|---|---|---|
| Food prep surfaces | Food-safe cleaner sanitiser | Approval on the label, rinse as directed |
| Utensils and boards | Sterilising or soaking fluid such as Milton | Soak time and strength on the label |
| Washrooms and bins | Stronger disinfectant or washroom cleaner | Keep strictly separate from food-area products |
| Front of house, handles, tables | Multipurpose or spray disinfectant | Cost per use, buy concentrate if daily |
| Ovens, ranges, extraction | Degreaser first, then disinfect | Grease blocks disinfectant, clean first |
Heavy grease is its own job and is covered in kitchen degreasers and hard-surface cleaners for catering. Washroom products are covered in toilet and washroom cleaners, and the everyday pot-wash spend in buying washing-up liquid in bulk.
How should a business buy disinfectant?
Buy by area rather than by price. Start from a list of the places you disinfect, food-contact surfaces, front of house, washrooms, bins, then match a product to each and check the label approvals before anything goes on the shelf. A single bottle bought to cover everything usually ends up wrong for the food areas and overkill everywhere else.
Read the contact time before you commit to a product, not after. A disinfectant with a long stated contact time can be perfectly good and still be unworkable in a cafe that wipes tables between customers. Fit the product to the pace of the room. Where a product is going into a rotation you run several times a day, trade sizes are the sensible buy, on the same reasoning set out in buying washing-up liquid in bulk.
Keep every product in its original labelled container, hold the safety data sheets, and store chemicals away from food. That is the core of your COSHH duty and it takes very little effort once the shelf is set up properly.

Frequently asked questions
What is the difference between a disinfectant and a sanitiser?
A sanitiser reduces bacteria to a safe level and is common on food-contact surfaces, while a disinfectant kills a higher proportion of germs and is used where stronger control is needed. Many products are combined cleaner-sanitisers. Whichever you use, the contact time on the label matters, leave it wet for the stated time to actually work.
What is Milton used for in a commercial kitchen?
Milton is a chlorine-based sterilising fluid used mainly for soaking rather than spraying. In a kitchen it suits utensils, chopping boards, cloths and small food-prep items that can sit in a solution. Follow the label for strength, soak time and whether a rinse is needed, and never mix it with any other cleaning chemical.
Can you use Dettol spray in a business kitchen?
Dettol spray works well on general surfaces, handles, bins and washroom areas. For surfaces that touch food, check the product is stated as suitable for food-contact use and follow its rinsing instructions. Many kitchens use a dedicated food-safe cleaner sanitiser instead, usually because trade concentrates cost far less per spray.
What is a food-safe disinfectant?
A food-safe disinfectant or sanitiser is approved for use on food-contact surfaces, typically meeting a standard such as BS EN 1276. Used and rinsed as the label directs, it controls bacteria without leaving harmful residue on surfaces that touch food. In kitchens and food areas, always choose food-safe products and follow the contact time.
How long should disinfectant stay on a surface?
Leave it for the contact time printed on the label, and keep the surface visibly wet for that whole period. Spraying and wiping immediately is the most common mistake and stops the product working. Spray a run of surfaces, do another job, then come back and wipe them in the same order.
Do you need to clean a surface before disinfecting it?
Yes. Disinfectant cannot reach a surface through grease, food debris or dirt, so it does very little on a soiled bench. Clean the surface first with a suitable cleaner or degreaser, then apply the disinfectant and leave it for the stated contact time. Combined cleaner-sanitisers handle lighter soiling in one pass.
