Drainage Residue

672 7
What does everyone use to remove the residue that is left on the bottom side skirts once the water or rain has drained through the drainage holes. General washing doesn't really seem to remove the "skid mark" nor has simple green. Is the only way to solve this problem to use a paint cleaner, polish and wax everytime I wash my car?

:dunno: I guess I don't understand what you are referring to. I don't seem to have a problem with this.
I have a sedan so there might be a difference. underneath each door there is a drainage hole for the water to run out. The water then runs out of the hole and down the side skirt. It has a tendency to leave a bad water stain or skid mark.
hmm, i can honestly say i didnt notice, but i will check the next time i'm at my car.

AFAIK, that's actually cosmoline (or something similar).

You're talking about the grease streaks running vertically
down the sideskirts, right?

I remember reading (here) that it would eventually wear off
enough to stop leaving marks, that the first year of ownership
would just be messy.

It comes off pretty well with just washing in my case.

In 3 months of ownership at the end of a TX summer, I can
certainly tell it's lightened up quite a bit - seems to be better
every time I wash the car.
Use a blower or such to blow the car before drying. Or, after drying, go for a spin and then redry the affected area.
Leave the doors open and let em drip a while. Also some of this is from water trapped on the doorsills so wipe those off too.
If you scrub hard enough and you have waxed relatively recently, it pretty much comes off. If it gets too bad and won't come off, I always went after just that spot with hand polish and hand wax.
