Today I did the interior of my Altis 1.6 2015, just one month old 
I sprayed Meguiar's quick interior detailer and wiped with a microfiber towel, dash, doors panels, trims, console and then applied a generous amount of Meguiar's Ultimate Protectant.
All new Corolla owners must do it once a month, otherwise the thristy black and greg interior would turn grey this summer.
