Ok so i just got done cleaning my rims and was onto detail the engine compartment, and when i popped the hood to my horror i have a milky looking stain all over the plastic on top of the radiator and on the hard plastic intake elbow and manifold. Now both pieces are hard black plastic. It looks like someone sprayed rim cleaner on it! I dont use wheel products under my hood so one im confused how it got there. But what i wanna know is if theres anyway i can get it off? Ive already used both types Gunk engine cleaner and degreaser and a few others that i cant remember of the top of my head. But my question now is CAN I GET IT OFF? AND HOW? HELP!!!:overhere

First off, :welcome to MOL!

Second, DON'T PANIC! Have you tried applying a dressing to the affected areas? You might try a few applications of Supreme Shine, Natural Shine, or M40 Vinyl & Rubber Conditioner and see if that takes care of the problem. What kinds of degreaser did you use? Did you happen to use Simple Green by any chance? Because Simple Green will stain certain materials. Not sure what to tell you beyond that. Welcome to the forum!

If gunk didn't work,then it's not oil contamination.

There's still no pic.(incase you think there is).

It sounds like something is encrusted on your plastic parts.If we could see,it would help a lot.

I don't think you can "remove" them
But maybe you can cover them up by treating it with a dressing

TrailHustler

yeah, ive posted the pics twice it keeps saying waiting for moderator approval. some of it has come off a little but the biggest stains are still there. some of it came off the intake, but NONE will come off the radiator except when i scratch then it comes off in very very small amounts

Maserati Mario

Hum...
So you can remove some?
Maybe an APC, a brush and some passion will work.

I've been having a look at your pics.Most of the splatter is all around your radiator.Have you checked the level of your antifreeze.Although that shouldn't stain like that.You can also check your refrigerant level(air con).If there is something wrong with the air con.you should see foamy air bubbles in the glass viewing receptical.
Probably,you could try to use the above mentioned...APC with a brush.Have you got APC?

TrailHustler
Jun 15th, 2009, 07:10 PM
yeah the first thing i did before i started cleanup was checked on all my fluids, hoses and caps. everythings good so no worries there, and no i dont have any APC

Maserati Mario

Your welcome.
Not sure what that is.
You don't need Meg's APC, any All Purpose Cleaner should work.

Eddie6th
Jun 15th, 2009, 07:17 PM
I know you are eager to clean this up.You need to check what caused that to happen.
If your engine is cold,take off the cap and check that your antifreeze/water is up to the neck.It looks like there has been a leak and while you were driving,the air entering caused it to splatter all over your radiator,which got caked on with the heat.The whiteness could be deposits from your cooling system.

I guess ill have to get into my shop tomorrow and see what kind of cleaners ive got around. i just didnt want to add to the mess just in case any kind of cleaners would react to the plastic, just like whatever did the mess to begin with.
I just talked to my friend that does my warranty work for me and he stopped by and said it definatly looks like rim cleaner, RIM CLEANER!... ive been letting my truck cool all afternoon and he poked around and he said that everything is cool. and warranty wont cover that unless it was actually anti freeze and even then it probably wouldnt cover cosmetic stuff anyway.

Since you say it scrapes off, I wonder if it could be clayed....

Maserati Mario

Well do a test spot.
APC's should be fine, I dilute Purple Power 10:1 and it doesn't do that to plastic.
Also you can paint them with a vinyl paint

Is that 'A Definite' as to what it is?

TrailHustler
Jun 15th, 2009, 07:40 PM
Its not any of my trucks fluids. Thats a definite. But what it is all together i dont have a definite answer for. i dont use rim cleaners because ive had
them ruin painted wheels and make my calipers look nasty so i avoid them all together.

Murr1525

Maybe we can just blame the service dept.

Must be something with a lot of minerals in it to dry like that, but not eat the plastic.

Eddie6th
Jun 15th, 2009, 07:51 PM
Okay.I know what kind of substance you are talking about.How it got there....?

Was anyone working on your car recently?

Do you have some kind of All Purpose Cleaner? like the ones mentioned above(i can't give you info of similair brands because they are different nanes here).

TrailHustler
Jun 15th, 2009, 08:03 PM
No, no one has been under my hood recently. my friend did make a good point i work security in a high gang activity area. im there to keep them out actually. and they have been doing alot of tagging lately. and i have to park in a "SECURITY ONLY" parking spot. other than that, theres no reason it should be under there.
I dont have any, ill have to run to the store in the morning.

Eddie6th

Okay,There are no definete's as to what it is???As long as you know it's not from your engine bay,then at least that's something you don't have to worry about.

I would go ahead with one of the cleaners mentioned earlier and use the recommended dillution.

Let us know how you get on.....:dp:

ok i tried simple green and megs all purpose...and nothing, all that stuff is still there. when it gets wet with simple green it goes dark as if its going away but as soon as i wipe it and it dries it comes back. i guess ill just have to keep working with it.Scottwax2

It seems that it is well stuck or stained in because of the heat that was created.Can you try and use a cleaner polish?Do a little test spot and see if it can bite into it a little.It's the only way that I can think you can do this.Going by your pics,the parts that are affected are plastic and plastic coated.I don't even know if plastX would have any effect here?

Get back to us.....

Maybe your only choice is to paint it.
Here's some I found at a PBE store
It's for plastic, carpet or lether.

That just gave me an idea :idea:

Just aswell you mentioned that Mario.

If you go to the tip&tricks part(Engine bay hoses),I posted a thread about spray painting plastics and rubber in the engine bay.It's really good stuff.It's designed for that and is heat resistant.It is also available in Black.

The only thing i'm wondering is if you can find it in the states.(I think it's made in Germany).

That could be another alternative?

You say you used Gunk and Black Magic? I'm assuming the 2-in-1 product for engines, but just to double check. Did you use them before you cleaned the rest of the truck, and then it dried like that? Gunk before the Black Magic or reverse?

If the junk can be scraped off with your finger nail, then sure there must be a chemical that will dissolve it and clean it away. How about trying the Gunk again? Or what about Amazing Roll-Off?

Okay my educated guess is that it is calcium from when water was on your hoses then the engine got hot and boiled off the water and left the mineral deposits. My recommendation is to get some CLR and test a small spot. The reason I say that is because if you can scrape them off then it is an external contamination. Use a tooth brush on the hoses with CLR then rinse and dry. If that works then you can dress them. The problem with vinyl paint is if you can scrape it off then you will be painting the contaimenent not the plastic. I have seen this thing before and it worked for my situation. Hope this helps.

Eddie6th
Jun 17th, 2009, 03:24 PM
Good point there RG.I think it'll come off with a bit of rubbing,with one of the above mentioned products.Better that than picking it off,as that could lead to a lot of scratches with soft plastic
If you find the lumps come off but has left stains,even after rubbing,hence it is smooth,you might have to go down the road of spraying it with a 'heat resistant' spray.They work well,and last.

CLR might do the trick, or you could try some plain old vinegar in a little water. It's good for calcium/mineral scale.
