Why is my charging port not working?

So 6 months ago I spilled makeup removing liquid in the bottom of my bag, and a lot of it got onto my charger cable, and it wouldn’t charge my laptop anymore. Bought a new one and it was working fine, then it would only charge at a certain angle, until a few weeks ago when it stopped charging completely. I bought another and it still wasn’t working. I sent my laptop to a PC repair place; they said i was using the wrong charger (i was using a 30w adapter instead of a 60w one). i bought a 60w charger and it’s still not working. they said the charger port of my laptop is fine but i’ve used other charging cables and adapters and its not working.
