Water in Speakers

Hello ~ I would take it in to be checked. The water may have cleared from the speaker but is still inside your Mac ….somewhere and that can cause further issues.

I mean, will it cause any further damages?

And, WHY did it sound the way it sounded?

Liquids and electronics do not mix.

Typical liquid damage gets worse over time not better...

If it works fine maybe you dodged a bullet(?)

or

you can wait and see if furthers issues arise over time.

Take it to Apple; if there is liquid damage Apple® will replace the entire logic board— a sizeable expense out of pocket.

If you have AppleCare+ it will cover a large portion of accidental damage.

I doubt the water was limited to your speakers as water is a very "thin" liquid (low viscosity) and likely ran down into into a lot of things.

There are many "home remedies" out there, but at best they all just postpone the inevitable ... a trip to Apple.

You may not have a water incursions problem, but if you do the longer you wait to have it evaluated, the worse the corrosion will get. It's your call.

Hello ~ If you check the OP’s date and time of post …24 hours have already passed. The correct thing to do in this case is take the MacBook in and have it checked by Apple or an authorized service provider. Water inside the unit will continue to do damage. They should back up the device and take it in to be checked out.
