Getting really stained marks out from under the sides (sills)

[Zappa]

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?

Have you clayed the car?

Nope, that looks like a complete nightmare to do. Doesnt it take a lifetime?

I would be worried about damaging the paint.

I've only ever polished and waxed it.

I'll take a few pics and post it up.

Grime!

Its actually worse on the other side..

Megs APC at a strong dilution will help... you'll need to either use a wash mitt that you dont care about or a soft'ish brush to get that lot off.

something like these might be worth a look as well

Yup get some tar bug remover on there and a good soak then clay it!
