what do I do if there is sauce in my charging hole?

Make sure you turn off the pc and take out the battery and charging cable.

clean the port using rubbing alcohol.

or if you have warranty talk to your manufacture.

Stop putting sauce in your charging hole. It's a sin.

I had a feeling it is gone because what you tried to do; cotton swab with medical alcohol to clean the sauce on the tip and another dry cotton swab it clean, let dry for an hour or 2 to be safe. Though I am not sure.

I knew about hot-plugging but this is a whole new level!

Why not buy a whole new cable? Its shouldn't be that expensive - around $5?

Just the wire, right? You can try washing it IN alcohol. The wire itself, you can safely wipe with water and soap and then just water. The ends, try shaking them in a glass of alcohol. You can wipe them off with q-tips. Stand dry for a day before using. Don't use acetone or nail polish remover. You might melt some plastic parts and short the wiring.

Lick it out

How much did the Macbook cost? And you put a bottle of sauce in the same bag? Have you considered psychiatric treatment?

cleaned it out with cotton swab ["Q-tip"] already? if so, it needs a technician to open the case and see what's what

You could try a cotton bud dipped in IPA (isopropyl alcohol), otherwise you will need to take it to a tech.
