The whole idea of this topic is to have us collaborate and share what should be done after an adventure. I'll start...
Do a thorough inspection of your undercarriage. Especially after playing in rocks. If you think you have spotted one or two things, get another set of eyes to find what you missed. If both of you think you got it all, you are probably wrong, so get a 3rd set of eyes. Repeat this inspection, with the same eyes, routinely so you can track things to see if they pose an issue or not and triage your build plan accordingly.
