Liquid Damage

bcyEzxGziLiquid damage is one of the most common issues we come across, beer, wine, coffee, you name it, we’ve had customers spill it on their Macs. However, all is not lost, 95 out of every 100 Macs that are water damaged are repairable, and without replacing the logic board. Don’t be a glass half full person, if your Mac has been subjected to even a small amount of water, it might work for a while after it has dried out, chances are it will start giving you problems a few months down the road.

Here are some tips on bringing your water damaged Macs back to life.

Warning, you carry out these steps at your own risk. MacAssist is not responsible for any damage you do to your Mac or yourself by following these tips.

  1. Disconnect from the power source
  2. Turn the Mac upside down and shake out any liquid
  3. Disconnect the battery. On newer Macs this will require unscrewing the bottom case
  4. If you feel confident enough, disassemble your Mac to allow any remaining liquid to drain and to allow cleaning


  1. Find a container big enough to put your logic board in, and completely submerge is in isopropyl alcohol with 90% concentration or above.
  2. Use a toothbrush or other soft brush to clean any debris from the board. You don’t need to vigorously scrub, just work gently and methodically. Pay special attention to ribbon cables and connectors.
  3. Dry the board, DO NOT USE a hairdryer on hot setting. You can use the cold setting or let it dry naturally in a warm place, under a lamp or an airing cupboard for example. Alcohol evaporates quickly.
  4. Reassemble your device. If your Mac was fully submerged, it is likely to need a new battery.
  5. Try switching it on again

If none of that works, or you just don’t feel confident enough doing this, get it to us and let us do it. The sooner the better.
