Gloss or matt wrap?
For gloss, just wash with regular shampoo and/or snow foam and then top up with the wax product of your choice. I use either DJSN or Envy FA on mine, depending on mood (usually FA though, too easy and gives awesome beadingness). Best thing to do would be to pop a ceramic coating on it before it gets too covered in swirls. I use Envy Revolution for my wheels, but clearly you don't want to be getting any of it on the wrap for a long period of time so just be careful where you spray it.
And be very careful when using a jetter on it, as you don't want to start pulling the wrap off by getting too close/using too powerful a spray.
But in general, just wash and protect as normal. Just avoid any abrasives (so polishes) or strong chemicals (fallout remover).
