Device will not power on after usb c replacement

Over the years Apple has moved to smaller and smaller discrete components as such using a toothbrush might be a bit too aggressive, pulling or damaging one or two. Orange Juice is both quite sugary and acidic, so if left on the logic board too long it can cause damage.

You stated it was still working before you took it apart so that leads me to believe the logic board was already in a fragile state.

Can you give us a clue where you live, country and nearest major city maybe we can aim you to someone who can help you.

What You Can Try-

Sometimes a dead battery can block power-up.

Disconnect battery completely.

Plug in charger with just the logic board and screen connected.

Wait a few minutes and try pressing the power button.

Observe any heat, buzzing, clicks, or even a warm spot on the board — this could point to a short.

Inspect Key Components Again

Use a magnifying glass or macro phone camera to inspect:

• USB-C port area (likely U7000 or similar chip for charging)
• Capacitors near the charging IC
• Any signs of pitting or green corrosion around chips or between pads

If you find even a tiny corroded component, take a close-up photo and identify it.

If nothing goes well, try to find a micro-soldering technician.

Sure!

Your MacBook likely has deeper damage from the orange juice, even though you cleaned it. The USB-C issue suggests the charging circuit or logic board may be damaged. Try a different charger, and check if power reaches the board (if you have a multimeter).

If it's still dead, it likely needs board-level repair or microsoldering. A local repair shop (not necessarily Apple) that handles MacBooks is your best option.
