Can I use hairdryer to dry MacBook?

Quick Answer

It is not recommended to use a hairdryer to dry out a wet MacBook. The intense heat from a hairdryer can potentially damage the internal components of the laptop. There are safer methods to dry out a MacBook like leaving it powered off in a dry environment or using compressed air. Prolonged exposure to moisture can cause corrosion so it’s important to act quickly but use caution when attempting to dry out electronics.

Is It Safe To Use A Hairdryer To Dry A Wet MacBook?

Using a hairdryer to dry out a MacBook that has gotten wet is generally not recommended. Here are some key reasons why hairdryers and other direct high-heat sources are not ideal for drying wet electronics:

  • The intense concentrated heat from a hairdryer can potentially damage electronic components. Delicate parts like the logic board, ports, and battery can warp or melt under excess heat.
  • Blasting hot air into the MacBook can push moisture further into small crevices and gaps, making it harder to fully dry out all areas.
  • The fans designed to cool the MacBook are not built to withstand high temperatures from hot blowing air. This can cause the fans to malfunction or seize up.
  • Using a hairdryer requires manually drying out the entire device, increasing chances of missing moisture in hard to reach areas inside.
  • The hot circulating air from a hairdryer can spread existing moisture to unaffected components before fully drying them.

So while it may seem like a hairdryer or heat gun can speed up the drying process, it often does more harm than good when trying to salvage a wet laptop. The intense localized heat and haphazard blasting of air make it a risky drying method to avoid.

Better Ways To Dry Out A Wet MacBook

If your MacBook gets splashed, dropped in liquid or exposed to moisture, here are some safer methods recommended to dry it out:

1. Power Off And Leave In Dry Area

Immediately power off the MacBook if it gets wet, as leaving it on can short circuit and further damage parts. Wipe off any excess moisture, then place the laptop in a dry, well-ventilated area. The natural circulation of air will allow it to safely dry out over 24-48 hours. Place it upside down at an angle to help moisture escape rather than pooling. Avoid dry rice or any desiccants as they can get stuck in ports.

2. Use Compressed Air

Use short bursts of compressed air to help blow out any droplets stuck in narrow openings and crevices that are hard to reach. This also helps circulate any trapped moisture to the surface. Make sure to follow all compressed air safety precautions and only use air pressure rated for electronics.

3. Disassemble And Clean Components

For very wet laptops, it may be necessary to disassemble them to clean out individual components. This allows thorough drying of the logic board, keyboard, fans, battery and other parts most vulnerable to water damage. Be very careful when taking apart a MacBook and only do so if experienced.

4. Seek Professional Assistance

For serious liquid damage, seek professional help from a repair technician. They have specialized tools and methods to fully dry out a MacBook and assess any damaged parts. A repair shop may use a vacuum chamber process to thoroughly dry each component without heat risk.

Signs Of Liquid Damage On A MacBook

If your MacBook has gotten wet or exposed to moisture, here are some common signs of liquid damage to look for:

  • Visible water droplets or condensation inside the screen/case
  • Corrosion signs like rust around ports or vents
  • Sticky keys, trackpad or USB ports
  • Distorted or flickering screen visuals
  • Laptop randomly shutting down or not turning on
  • Strange electrical smells from the vents
  • Fan constantly spinning loudly
  • Speakers making crackling or popping sounds

Any of these are telltale indicators moisture has reached internal components and immediate drying steps need to be taken. The longer moisture sits inside, the higher chance of short circuiting or corrosion occurring.

Can MacBooks Be Fixed After Liquid Damage?

MacBooks that suffer minor liquid damage can often be repaired and restored to full working order. However, the degree of water exposure and which parts got affected will determine if a fix is possible. Here are some factors that influence repairability:

  • Drying Speed – The faster excess moisture can be removed, the less chance of major damage occurring.
  • Parts Affected – Liquid reaching delicate electronics like the logic board often requires part replacement.
  • Corrosion Level – How much rust or oxidation built up inside from the water.
  • Power State – Whether it was powered on or off when getting wet affects damage.
  • Liquid Type – Water, coffee, soda etc. can impact the types of damage.

Minor exposure with no major corrosion may just require thorough drying and cleaning. But more serious spills or delayed drying can make a MacBook unsalvageable if the main logic board is fried. Get a professional assessment first before attempting DIY repairs.

How To Prevent Liquid Damage To A MacBook

Here are some tips to help prevent your MacBook from getting damaged by spills or moisture:

  • Keep drinks and liquids away from your workspace when using the laptop.
  • Do not leave MacBooks unattended around children or pets who may spill on them.
  • Carry the laptop in a padded case when traveling to protect from rain or spills.
  • Shut down and store the laptop away when not in use for long periods.
  • Use a waterproof cover or silicone keyboard cover when using in risky settings.
  • Avoid eating or drinking when using the laptop to prevent accidental spills.
  • Regularly inspect the laptop for any leakage or condensation issues.
  • Keep the laptop from getting too humid or wet by minimizing use in these conditions.

Practicing careful handling habits goes a long way in preventing costly liquid damage repairs down the road. Be prepared for spills by having rice or paper towels handy to act quickly. Taking preventative measures helps safeguard your investment.


Using a hairdryer to dry out a wet MacBook can seriously risk causing further damage due to intense concentrated heat. It is safer to power off the laptop and let it air dry in a controlled environment. Seeking professional help for assessment and component cleaning is recommended if moisture exposure is significant. With proper care and quick response, minor spills on a MacBook can often be addressed before permanent damage sets in. Just be sure to avoid risky methods like hairdryers that could make the situation worse. Implementing prevention habits will help avoid liquid damage in day-to-day use.
