When you apply a disinfectant or any cleaning product, it’s essential to know that you’re using it correctly. Every product is designed to work in a specific way — and if it isn’t used as intended, it simply won’t deliver the level of cleaning or disinfection you expect.
Keeping surfaces and equipment clean is vital for maintaining hygiene standards and reducing the risk of illness among staff and visitors. But even the best cleaning product won’t work properly unless you follow one key rule:
The product must stay wet on the surface for the correct amount of time.
This is known as the contact time.
In simple terms, contact time is the length of time a disinfectant needs to remain wet on a surface to be effective. If it dries too quickly — or is wiped away too soon — it cannot kill the bacteria or viruses it was designed to target.
Contact times vary widely depending on the product and what it is designed to kill.
Some examples:
The longer the required contact time, the harder it is for staff to use the product correctly. Imagine applying a disinfectant and having to ensure it stays visibly wet for half an hour — it’s simply not practical in most workplaces.
This is why product selection matters. Shorter contact times mean better compliance and more reliable results.
In the post‑COVID world, correct chemical usage has never been more important. Manufacturers test their products extensively to determine the minimum time needed for the disinfectant to work effectively.
For example:
If a sanitiser has a 60‑second contact time, it must stay wet on the surface for the full 60 seconds. If it dries in 20 seconds — or is wiped off immediately — it cannot perform as intended.
We’ve all seen it happen: a restaurant worker sprays a table and wipes it instantly. It looks clean, but the disinfectant hasn’t had time to work.
This means:
Correct contact times are essential for effective infection control.
Several factors can shorten or lengthen contact time:
Understanding these factors helps staff apply products correctly.
