Brown stains on paint. Need some info

So I have these brown stain on the paint it's some type of road grime. It starts off as a black spec of something after a wash it come off but leaves some type of stains I can't remove. What I have tried so far. Soap scrubbing, rubbing compound, wax, iron-x, and goo gone. I could try to wet sand but really don't want to wet sand every time I get those stains. I seem to get a need ones every week it seems. Any one have any idea on how to remove them? Literally just washed the truck yesterday morning and those 3 spots where not there. Today I walked around the truck saw the spots and noticed the stains. Really annoying, wash the truck ever weekend keep it as clean as I can and wax it but still find damn things that stain the paint.

 

have you tried alcohol or some mild solvent? Starting as black and then turning brown is making me think it's tar based. mild solvents will help you there.

 

Road tar...check local auto store forgot what its called it removes tar with tough bugs as well

 

Ok I'll give alcohol a shot and see.

 

Do they "tar and chip" your roads where you live? I drove through some of that shit years back in my truck and it got all over the truck...

This takes it right off with minimal rub

Try Lacquer thinner on a rag just wipe it on it will take it right off

 

Alcohol was a no go. I'll have to keep experimenting.

 

Do the thinner method !!
If that doesn't work try lime way or CLR. It looks like tar but may be brake dust fragments believe it or not

 

Ok I'll have to look around the house for som thinner hopefully I can find some.

 

Alittle more info on the spots. So I also noticed that when I first find them the black spot is very easy to wipe off with a micro fiber cloth. No scrubbing of anything just a quick wipe and it come off but then leaves that brown stain.

 

It's tough to tell how big the spots are in the pic but could it be "rail dust"? Semi-metallic brake pads throw small, hot metallic particles that stick to the paint and start out as a little black spot and quickly turn to a small but much more noticeable rust stain. A clay bar works wonders for getting rid of stuff like that.

 

You can also try a clay-bar. That seems to work wonders.

 

Also another one made by Turtle Wax also check out chemicalguys.com

 

You weren't following a Chevy were you? I've noticed that when you get too close to one they get scared and poop a little

 

I'll give the clay bar another shot but so far no luck with anything. Tried a bug and tar remover and no luck. Nothing seems to affect it. Not even slightly faded. I don't think its rail dust I tried ironx on it and all the rust spots around it I saw come off but the brown spot just holds strong. They are about the size of a BB

 

For stubborn stuff I like to try a polish. I've got some of the commercial grade Maguires stuff. It comes in different grades of cutting compound. Also it's cheap but believe it or not that scratch out stuff works really well as a starting point. But I always follow up with a quality polish and wax after I get whatever it is out.

 

Try the mothers clay bar kit. I just waxed mine this weekend for the first time and that's what took mine off. If my understanding is right, the white on these new trucks don't have a base coat/ clear coat process which is why the "rail dust" sticks like it does. My white chevy did the say thing and that's what they told me to use. It seems to take it off with some elbow grease.

 

Can't feel the stains. Tried a rubbing compound the other day with no luck and also a clay bar. I'll have to try a better tar remover. And or a type of thinner. My last hope it fine one in a hidden spot and try to wet sand with 3k and see if I can try to make it fade if not get rid of it.

 

I'd be extremely careful sanding that textured area - even with 3k... the clear on these things is super thin, thin enough to burn through with 3k on a high spot.

 

Yeah I definitely do not want to do that. I I'll keep trying stuff to see. Just sucks having it all over the doors

 

Once you get the stains out get a good paint sealant and a couple layers of wax to hopefully prevent it from happening again in the future. Then in between waxing hit it with a quality spray way to help maintain the layers of wax and protection. Btw no clearcoat on white.

 

After long test and research and giving up I finally figured out what the stains are. They are from the tire shine. Washed my truck today though I got the heavy amount of shine off but some slung off and after wiping off noticed the same stains. Found info that it happeneds when the tire shine mixs with the release agents from the tires. Makes sense since I have new tires and just starting happening. Still can't get the stains out though.

 

What kind of tire shine product are you using? Pics would be great!

 

I use chemical guys.

 

Why don't you call chemical guys and tell them what's going on and see if they have a solution for you. At this point it's their product staining your paint.

 

Idk know if it's ther product though. What I have read was that the release compound on the tires has to be cleaned off really good because if it's mixed with the tire shine it can cause it to stain. I don't know I might see I'll shoot them an email and see. Either way I've seen a few post on how white cares and new tires with tire shine have the same stains

 

Saw these spots on my Tacoma before I started using chemical guys products.

 

Just strange that after my new tires I started to get the stains. I really think it's the chemical they use when molding the tires is still on the serface and when it gets some type of product that can mix with it, it causes it to mix and since I have a 0 offset it throws more on the paint. Before the new tires I had stock and would always put shine on them also but but never had a stain even using the chemicals guys tire shine.

 

FWIW I've been using Denatured Alcohol for years to clean anything I can't get with WD-40. I've tried goo gone and the other purpose built products to no avail. I'm an electronics technician by trade and was in the printer repair business for many years. Printers we dealt with were plastic and typically had all kinds of dumb shit stickers on them which we had to clean off so we could paint the plastic housings as they were yellowed from age. Denatured Alcohol would clean anything and everything without a residue left as it is a clean burning fuel for boats and campers. Also used it to clean circuit boards from rosin and other contaminants. I first tried it on my 1974 charger when I got road tar many moons ago in the 1990s and been using it ever since. It will clean EVERYTHING from the surface so a rewax/sealant is needed after application. I've used it to clean off the tape from emblems after debadging, road tar, bugs, etc.
