Just put it somewhere where the water can drain and it can dry out. A little bit of air circulating might help dry it faster.

It is common for a lot of electronics to actually be washed in something that looks like a giant dishwasher. Admittedly not all components are suitable for washing but a lot are.

We have a few robots that have been drenched multiple times by intense thunderstorms. We just take our time and let them air dry after dumping out the excess water.

Some of the bearings we didn't have to change out for a couple of years.
