I just read a review about CG's Citrus Wash and Clear. It is merely a conventional shampoo, minus the glossy agents in the other version. So, again it won't remove wax normally.

Clean up after polishing...

If the finish is perfectly clean with minimal dust, you can just straight into your finishing steps (i.e. waxing the car).

If the finish has significant dust, it would be a good idea to re-wash the car and thoroughly dispose of the dust (it can get into everything so be thorough).

If you are concerned about filling properties (i.e. the return of defects), you can prep-sol the finish and verify the condition and re-polish areas as necessary.

And congratulations on the new hobby. It's definitely not an easy one but it can be rewarding to look back on a swirl-free finish in the sun and know that it's your work.
