1. Gather the Necessary Tools

Before cleaning the logic board, ensure you have the right tools:

• 99% isopropyl alcohol (lower concentrations may leave residue)
• Soft-bristle brush or anti-static brush
• Microfiber cloth
• Plastic tweezers (for handling components)

2. Power Off and Disassemble the MacBook

To avoid electrical damage, power off the MacBook before cleaning.

• Disconnect the charger and any external devices.
• Unscrew the bottom panel using a Pentalobe screwdriver.
• Carefully disconnect the battery before handling the logic board.

3. Clean the Corroded Areas

Once the logic board is exposed, locate the corroded areas.

• Dip the soft-bristle brush in 99% isopropyl alcohol and gently scrub the affected areas.
• Wipe excess alcohol with a microfiber cloth.
• Let the board dry completely before reassembly.

4. Inspect and Reassemble

After cleaning, inspect the board for any remaining corrosion or damaged components.

• If corrosion has severely damaged components, professional repair may be necessary.
• Reconnect the battery and reassemble the MacBook.
• Test the device to ensure it functions correctly.

Conclusion

Cleaning corrosion from a MacBook Pro logic board requires patience and precision. Using isopropyl alcohol, a soft-bristle brush, and careful handling can remove corrosion and restore functionality. However, if the damage is extensive, professional repair or logic board replacement may be required for long-term reliability.
