Whiteout owners: rockchip guard yellowing?
 

Was wondering if other whiteout owners are having the same issue as me. The other day I was washing my car and noticed the rockchip guard along the lower rocker of my whiteout has yellowed and it looks like there are many little yellow spots as well. This is on both sides (see pictures).

Tried taking it to the dealer and they tried different cleaners on it but couldn't do anything about it. They had a Toyota rep document it and apparently the rep had seen some other cars with this issue. They had mentioned that it looks like it was either stained or bleeding from the inside out?

I was very frustrated to find this, although it's not that noticeable further away from the vehicle, but still noticeable enough to where I'm not happy with the car. Especially since there's a difference in color with the white.

And no I did not drive over paint (dealer actually asked me that). My car wash soap is chemical guys wash and gloss with blackfire wet diamond wax. :sigh:

clean it more often, and use a good bug remover/tar remover on it.

Nope this definitely isn't pollen since none of the trees even have leafs up here yet.

I've also tried goo gone and that hasn't worked either :(

maybe try a mr clean magic eraser? I've used that on various white things including white macbooks and it makes it look like new.

Try viniger

You wouldn't happen to use armorall? It can stain paint.

Try IronX?

Nope, no armorall.

Thought about trying ironx, but at this point I feel like it's stained inside. Will try magic eraser this weekend and maybe ironx afterwards. Honestly I'd rather just give up but something keeps pulling me back to try to fix it.

Thanks for all the recommendations! Seems like I'm the only one with this issue, which means it must be something stained from the outside....grrr

damm...i only have 17xx mileage and washed 3-4 times but didnt really pay attention on this. I will check mine

I recently got some dirts on rocker panel as well but not like OP's entire area. just few spots. I tried googone, bug remover, rubbing compound and does not come off. :(

You just need to clean it.

+1 for the magic eraser, rinse afterwards tho

Maybe you ran over a freshly painted yellow line in the road?
