If it does not clear -- place in sealed jar with rice. Better get some desiccant from the hardware store. If you can't find, then heat some charcoal in the oven. Place hot (not burning) in a sealed glass jar. When this cools, add the camera. Sounds crazy but heating charcoal activates it and it will act as a desiccant (drying agent).
Your lens is most likely foggy from condensed moisture. You can try putting it in a plastic bag with some material that absorbs the moisture. Silica gel packs, like those that are often packed with sensitive equipment, would be ideal for the job, but some dry rice may help, too. Putting the camera in a warm and very dry place may work, too. I dried my phone'...
Living in Florida, which is a semi-tropical area, condensation forming is a major problem. Little somewhat circular darker spots will be seen in RAWs and JPGs. The only solution is to slowly acclimate your camera (even the weatherproof Pentax 645Z) slowly to the change in temperatures when you go from air conditioning to the hot and sometimes muggy elements.
