A glass of water knocked over beside a laptop. Coffee across a keyboard during a meeting. A company phone dropped into a sink. A sudden downpour while an employee is travelling between appointments.
Water damage often happens in seconds. What happens during the next few minutes can make a significant difference.
For a private user, a damaged device is frustrating. For a business, the consequences can be considerably wider. The affected phone or laptop may be used for customer communication, email, Microsoft 365, CRM systems, authentication, financial applications and access to company information.
The first priority is therefore not to find out whether the device “still works”. It is to prevent further damage.
The first rule: stop using the device
One of the most common mistakes after a spill is immediately checking whether everything still works.
People press buttons. They open applications. They connect a charger because the battery is low. They repeatedly switch the device on. That can make matters worse.
If liquid has entered a device, electrical power and moisture are a poor combination. Dell, for example, advises users who spill liquid on a laptop keyboard to turn the laptop off immediately, drain excess liquid and allow it to dry thoroughly before attempting to use it again.
For a business device, resisting the temptation to “quickly send one more email” may help save the hardware.
The first 30 minutes: what should you do?
There is no universal 30-minute deadline after which a wet device suddenly becomes irreparable.
However, the first half-hour is important because this is when you can stop power reaching the device, remove surface liquid and avoid some of the mistakes that can increase damage.
First 5 minutes: switch it off
If the device is operating, shut it down as quickly as reasonably possible. Then disconnect:
- the charger;
- docking stations;
- USB devices;
- external monitors;
- headphones; and
- other connected accessories.
For a laptop with an easily removable battery, disconnecting the battery may also be appropriate if this can be done safely and without dismantling the machine. For a desktop computer affected by a spill, disconnect it from mains power before attempting further action.
The important principle is simple: do not continue supplying electricity to a device that may have liquid inside it.
5-10 minutes: remove excess liquid
Wipe visible liquid from the exterior using a clean, absorbent or lint-free cloth. Do not vigorously shake a phone or repeatedly turn a laptop in every direction. The objective is not to send liquid further into the device.
For an affected laptop, allowing excess liquid to drain away can help. Dell recommends tilting a laptop after a spill to drain as much liquid as possible. For a wet iPhone connector, Apple recommends gently tapping the iPhone against your hand with the connector facing down before leaving it somewhere dry with airflow.
10-30 minutes: leave it alone
This is often the hardest part.
- Do not switch the device back on simply because the outside now looks dry.
- Do not reconnect the charger to “see whether it charges”.
- Do not assume that because the display comes on, the problem has disappeared.
Liquid may remain around connectors or internal components even when there is nothing visible from the outside.
Apple specifically warns against charging an iPhone while its connector is wet because the connector pins can corrode and suffer permanent damage. Its guidance says that drying can take considerably longer than 30 minutes and, in some cases, up to 24 hours.
For laptops, Dell similarly recommends allowing a liquid-affected machine to dry thoroughly for at least 24–48 hours rather than immediately putting it back into use.
Don't put it in rice
The bowl-of-rice solution has survived remarkably well as an internet myth. It should not be your corporate IT recovery procedure.
Apple explicitly advises users not to put a wet iPhone or MacBook into a bag of rice, because small particles can get into the device and cause damage. Apple also advises against external heat sources, compressed air and inserting objects such as cotton buds or paper into wet connectors. That means:
- no hairdryer;
- no radiator;
- no oven;
- no compressed air into connectors; and
- no rice.
Dry airflow and patience are considerably safer than trying to force the process.
But my phone is water resistant - isn't it protected?
Water resistant does not mean waterproof. Modern smartphones can offer impressive protection against accidental liquid exposure, but their resistance has limits.
Apple states that splash, water and dust resistance are not permanent conditions and may decrease through normal wear. Samsung provides similar advice, noting that the water resistance of Galaxy phones can weaken over time. This matters particularly for business phones that may have been in use for several years.
A corporate smartphone that was highly water resistant when it left the factory should not automatically be assumed to have exactly the same protection after years of daily use, drops, repairs and general wear.
Water, coffee and soft drinks are not the same problem
The term “water damage” covers a surprisingly broad range of accidents. Clean water is one thing.
Coffee, tea with sugar, fizzy drinks, juice, alcohol, seawater and other liquids can introduce additional contaminants and residue.
Dell notes that the amount and type of liquid can affect whether a laptop suffers permanent damage, while Samsung specifically warns that water-resistant phones should not be exposed to substances including salt water, soapy water, oils and liquids containing alcohol.
So when speaking to a repair technician, saying what was spilled can be just as important as saying that the device became wet.
When is water damage too late to repair?
There is no reliable countdown clock. A phone recovered quickly may still suffer serious internal damage. Another device brought in considerably later may remain repairable.
What matters includes:
- the amount of liquid;
- the type of liquid;
- where it entered;
- whether the device remained powered on;
- whether someone attempted to charge it;
- which components were affected; and
- how much internal deterioration has already occurred.
Signs of serious damage can include a device that no longer powers on, intermittent operation, screen problems, keyboard failure, charging issues, unusual heat or repeated shutdowns. But even then, the correct conclusion is not necessarily “throw it away”.
A professional diagnostic assessment is needed to determine whether repair is economically sensible.
The point at which it is genuinely “too late” is usually when the damage has made repair technically impractical or the cost of restoring the device is no longer sensible compared with replacing it.
Why water damage is different for a business
For an organisation, the value of the physical device is only part of the equation. A water-damaged corporate laptop or smartphone may also mean an employee temporarily loses access to:
- corporate email;
- Microsoft 365 or Google Workspace;
- CRM platforms;
- customer information;
- authentication applications;
- internal messaging;
- cloud platforms; and
- business-critical files.
That creates an additional cost: downtime.
If a £800 laptop is out of service for several working days, the financial impact may go well beyond the repair bill. This is why businesses should have a simple procedure employees understand:
Spill → power off → disconnect → don't charge → report it → arrange professional assessment.
It is considerably better than allowing every employee to develop their own emergency repair technique from something they found online.
Corporate devices also require careful handling
A company phone or laptop may contain sensitive information or provide authenticated access to sensitive systems. When sending a corporate device for repair, businesses should therefore consider more than the technical fault.
Internal IT policies may require actions such as recording the asset, informing the IT administrator, protecting account credentials, remotely managing access, backing up information where appropriate and maintaining a clear record of who is handling the device.
A damaged corporate machine is still a corporate asset.
The fact that someone spilled coffee over it does not change the organisation's responsibilities around data and device management.
Water-damaged business devices? CellSmash can help
For London organisations, acting quickly after liquid damage can help determine whether a device returns to work or becomes an unnecessary replacement expense.

For businesses managing multiple employee devices, CellSmash also offers business repair services and bulk repair support, helping organisations reduce device downtime rather than treating every damaged phone or computer as an isolated consumer repair.
If a member of your team spills water or coffee over a corporate iPhone, Android phone, tablet or laptop, the first response matters.
Switch it off. Disconnect it. Don't charge it. Don't put it in rice. And don't assume that a device which looks dry is necessarily safe to use.
Then let a professional determine whether it can be saved.
