Wash it with soap and water to remove dirt and previous wax
I use Mother's claybar - excellent results if you've never done it before, definitely a must try. Leaves the paint as smooth as glass.
Then follow up with Meguairs Ultimate polish with my 6 inch orbital polisher to make the job easier.
Finish up with some Zymol liquid wax and plenty of microfiber towels and buffing.
Turtle rubbing compound to clean the yellowing off the headlights.
You can do it without the polisher, but it takes more effort/time.
Inside I just use Meguiars Gold Class leather cleaner and interior detailer.
And some simple green on the carpets if needed.
I learned a lot from perusing this thread.
Not an expert, but have certainly improved my results.
She will keep it in the garage for a couple of weeks before she'll break down and risk getting it dirty, LOL..
Thanks for the positive comments guys...
