I spilled a Diet Rite ZERO cola on my 2020 MacBook Pro. Did not try to wipe it of for fear of spreading it. I immediately turned it off and over over on a towel and left left it it key board down on the towel over the table edge in an inverted "L." That evening, I elevated it on two blocks in the same inverted position to allow ventilation and left it over night. The next day I started it up and it worked perfectly normal. I tested all the keys on a TEXT EDIT worksheet and they were fine with neither sticky key nor sticking keys, thanks to the drink being sugar free. There was no stain from the cola.
