How do I get this off?

WD-40!!!!!!!!!!!!

 

If those are aluminum running boards, and it's wax, Dawn and a scrub brush.

 

It' rubbing compound or glaze from being buffed.
Toothbrush &alcohol

 

On another note. What running boards are those ?

 

They are the Cast Aluminum Running Boards by Toyota

 

It looks like a pain in the ass on a 4x4 first mud puddle and there you go busting your ass with a scrub brush.

 

I wouldnt use simple green. search nitric embrittlement simple green.

 

Remove them completely from the truck. They just get in the way and ruin your pants. I hate mine.

 

time for sliders...

 

Hmmm.....Looks a lot like something on a stained dress that they talked a lot about on the news during the Clinton Presidency.

Good luck!

 

Creamy peanut butter can be used to remove wax from black plastic trim. You might give it a try.

 

Thanks for the head's up. Doesn't look like it's an issue in this particular instance.

 

They look nice. I have the OEM set from gen 2 and they have a ABS plastic skin over top of the metal frame.
Yours look more like a bed liner paint finish

 

Just an update to anyone curious. Was not able to get it off with some of the more simple ideas you all gave. Did not want to try anything crazy to risk damaging it so I took it to the dealer and they apologized for delivering the car in that condition and they are going to repaint them for me for free.

 

jizz stains are hard to remove.

 

Hell’s Revenge trail in Moab would have taken those off...oh, you didn’t mean the steps, did you?

 

Black paint

 

Wait until Christmas and ask Santa to remove it for you.
