First try using a bulb blower (never used canned air, it can cause damage). Hold the camera pointing down and keep blowing it out for a good long time, 30 seconds to a minute. That can sometimes do the trick and avoid a wet clean.
Also note that your image may start suffering from diffraction-related softening at those apertures on a micro four-thirds size sensor. It was worse with the original BMPCC (super 16 size sensor); I can't go beyond f8 without noticeable softening and it's pretty much unusable at f16. Less of an issue on the BMPCC 4K but f16 might start to be affected.
