Not a lot.
Hoes it down. I use soapy water with a little bit of bleach on the white inside.
Look at all the seals, I apply a light coat of WD or whatever I have laying around to soften them up. If any off the rubber shows some cracking I put a little bit of silicone to repair.
Pretty much it, put back on the jeep bolt down. Take a ride to the car wash, good way to check for leaking, better to fix now then wait.
Lastly cry-summers over
