Welcome aboard for sure. I saw your sticks. Instead of directing to posts/threads, let me just answer you.
I'll keep them out for a little while so there not to wet then they get staged depending on what they need. I'll use some dry leaf at times to wick away moister. At times I'll roll drier so they can be burned sooner.
Prepping leaf for rolling involves wetting them down so they can be manipulated so they don't break up to much.
It will take whatever time is needed to absorb the water. They need to dry for rolling with wet leaf may cause drying problems.
Shake and brush of some of that dirt before you wet it down. If your going to rinse leaf off, shake off the access. If your going to mist leaf off, shake off the access.
When your working the leaf out, (stretching out the crinkles) rinse your hands of and return to working the leaf out. It is a little tedious but, the dirt will get worked out.
