A bottle of cleanser spilled inside my bag and some of it got into my iPad A16's charging port. I'm currently in another city and can't get rubbing alcohol until possibly several days from now. I tried drying the port with tissues, but the iPad still shows a liquid-detected warning and won't charge. Is it safe to leave it alone overnight, and can it remain undamaged until I'm able to clean it properly?

The most important thing is avoiding power while the port may still contain liquid or cleanser. Keep it disconnected, avoid repeatedly checking it with a cable, and let it dry in a clean, ventilated place. If the warning remains after it has fully dried, professional cleaning is the safer option.
Stop trying to charge it while the liquid warning is appearing. Since this was cleanser rather than plain water, leave the iPad powered off if possible, keep the port facing downward, and let it air-dry naturally. Don’t push tissues, toothpicks, alcohol, or anything else into the port. Waiting several days is generally safer than repeatedly connecting a cable while residue or moisture may still be present.
Cleanser can leave conductive or corrosive residue even after the visible liquid is gone, so drying alone may not completely solve the problem. Once you can get the proper supplies, have the port cleaned carefully—or take the iPad to a repair shop. Don’t spray general-purpose products into the port or force anything inside, and don’t charge it until the warning disappears and the residue has been dealt with.

I was worried that waiting for alcohol would damage it, but I’ll leave it unplugged and let it dry naturally until I can clean it.
