MacBook Pro got rained on. I disassembled it. Seems dry. Does it still need rice treatment

Spill Cleaning

And, don't think that just because it was two teaspoons and not a glassful that there is a difference.

Some liquid has just spilled into your Mac. What should you do?

Do

• Immediately shut down the computer and unplug the power cord.
• Remove the computer's battery (if you can)
• Disconnect any peripherals (printers, iPods, scanners, cameras, etc.)
• Lay the computer upside down on paper towels to get as much liquid as possible to drip out.
• Note what was spilled on your Mac.
• Bring the computer into an Apple store or AASP as soon as possible.

Don't

• Don't try to turn it back on. Liquids can help electrical current move about the components of your Mac in destructive ways.
• Don't shake the computer (this will only spread the liquid around).
• Don't use a hair dryer on it (even at a low setting a hair dryer will damage sensitive components).
• Do not put in a bag of rice in as much as rice will get into the ports and optical drive and do further damage.

As a former laptop repairman,

we used large bags of DESICANT ,

put the laptop taken apart inside a large tuperware box with the desicant,

and put a heating pad under it on medium.

3 days of that, unless it was ALREADY DAMAGED, almost always worked..

Rice is not a good desiccant. Get a proper desiccant (Silica Gel, Molecular Sieve, or Calcium Sulfate) and place that in an open container with the item, and put both in a sealed plastic bag (or at least a large garbage bag), and let it sit for a few days. This will dry it out.
