sides

There is quite a heavy dirt level at the sides, at very lowest part of the car, almost under it. I can get everywhere to shine up lovely and gleaming, but near the bottom at the sill area on the outside, there is grime which I cannot shift no matter how hard I scrub! Any tips?

Has anyone else noticed this phenomenon with their aircon, now that the weather has taken a colder turn and we're starting to use the heater rather than the cooling.... When I used the aircon in the summer, say it was a hot day and I started the car and switched the unit to 17 degrees on...

i will probably be able to figure it out eventually but has anyone who's done it give me a quick heads up on removing the two side carpets? do i need to remove the plastic bit on the tailgate or the bits the parcel shelf sits on? ta! :)
