Do not put it in any oven to dry, but in the sun for 15 minutes can help warm up the body can help to kickstart things drying. The trackpad has very thin gaps and capillary action will wick astounding amounts of liquid inside a Mac - so be sure to never spray on to the hardware, always dampen the cloth and then bring the cloth to the device once you’re sure it’s not soaking and only lightly damp.
If you get issues after 15 minutes, I would power off and never start again until you’re sure the inside isn’t still wet. You can short circuit and damage things in seconds. Power off immediately if you suspect a spill or a soaking cloth sat on a device for even a few moments.
Since you're three days in - it's almost certain you have so much water still in it, that failure is inevitable and you will need a repair much sooner than if it didn't get wet. Or the water is gone, the damage is done and you will have this instability until it overloads something else. Could run like this for years - could be the last moment you have it working. That depends on exactly which trace / part got wet.
