You should Clay the car once every 6 months (and a chemical cleaner such as Tardis for large tar spots etc) or so as a rough guide to make the paint as smooth as glass, then followed by a Glaze or light polish if the paint even needs it, other than that you should only be topping up the sealant/wax protection to maintain the finish - not removing paint every week.
It's fair enough giving out advice but don't give out the wrong advice.
What to do is clean all surfaces as best as you can with an All Purpose Cleaner ( Meguiar's All Purpose Cleaner | Meguiar's Car Care & Detailing Products ) and then follow it up with a rather amazing product called Carpro So Pure ( CarPro So Pure | CarPro Car Care & Detailing Products ). This product was one of the best products of 2010 due to it's ability to completely eliminate (not just hide them) strong odours such as smoke.

Even if you have iron filings contaminating the paint then there's even a product for that called Iron-X ( CarPro Iron X | CarPro Car Care & Detailing Products ). All these products will safely deal with whatever situation you're faced with WITHOUT removing any paint - there's absolutely no need to machine polish with a heavy abrasive or re-spray.
