Wash and Wax that is safe or the siding

Unless I am missing something, is there a specific wash and wax we should be using? I don’t want to hurt the finish, I know not to use something petroleum distillates over the decals. How about everything else?

Trying to get ready for the season!

I wash with a soft detergent and “wax” and with RejeX

I go right over the decals and all. It has been noted over and over to be decal safe.

I like Meguiars RV wax.
