Sa exterior cleaning, damp microfiber towel kung minor putik lang na natuyo. Pero kung kailangan ng paligo, gamit kong pang-shampoo sa ngayon, ZIP Wax. Inuubos ko pa kasi. Ilang taon na rin sa akin ito, hindi mabilis maubos, kasi, napakadulas ng body ng Avanza ko, thanks to NuFinish The Once-A-Year Car Polish.
I also use NuFinish Scratch Doctor to get rid of scratches...
Turtle Wax ICE to clean the interior (para sa grabeng dumi sa panels). Mabango siya. Kung hindi makapit ang dumi, kahit damp microfiber towel din lang. Kung dust lang, kahit iyung small CCD (exclusively used for the interior) lang or dry microfiber towel.
I've never used Carnauba Wax. My officemates use it. I've exclusively used NuFinish ever since I got my Avanza. I find
NuFinish to be better in terms of looks (shinier) and longevity.
HTH...
