A good one-step cleaner/wax should tackle that no problem, you should consider buying a gallon as that's a lot of real-estate to cover.
Do a quick and simple test using some ColorX by Meguiar's. Apply to just a small section, work in well, let dry and then wipe off and inspect. If it looks more clear with good gloss then you're lucky and probably just about any quality cleaner/wax will work.
If you run into any problems like hard application and wipe-off and it doesn't look good after you remove the residue then probably nothing will work.
ColorX is fairly Bubba-Proof.
