Question Car cover melted on chrome side pipes

I'm hoping someone has had this happen and there's a happy ending. Western Washington has been experiencing some unseasonably warm weather these past couple of weeks so I took full advantage this past Tuesday and decided to go for a ride around the lake. Much to my dismay I noticed brown residue on my sidepipes and my car cover burnt. Apparently I put the cover on too soon on my last venture. I've tried acetone and it took alot of it off but any self discerning critic will notice the residue which remains.
Any Suggestions?

Marty

Marty,
The same thing happened to my dad's cobra and we used some of that orange hand cleaver with the pumice in it and a terry cloth rag. It came off fairly easy.

Got the exact same problem.

I use a medium rubbing compound with two rags and it comes off.

If you are fighting chrome, you might want to try a chrome cleaner.

DO NOT USE STEEL WOOL!!!!!

If you use the Orange hand cleaner make sure it doesn't have any grit or it wil scratch the chrome. Oven cleaner will probably clean it up with out any grit.

This is why if you're going to hit your pant leg against a side pipe you would want to be wearing cotton. Nylon or polyester will weld to the pipe.

Melted my pant leg onto the pipes a week or so ago. The wife was thrilled

The melted plastic blob stayed on the pipe for a few days and then magically popped off in a single piece. Maybe the temperature changed and the CTEs were sufficiently different to break the adhesion. You might try dry ice if the adhered material is plastic-like...

BTW, I also have a car cover with holes in it from the pipes. Sh!t happens...

Thumbs up Steel wool. Really. I'm not kidding.

Make sure it is 0000 or it will scratch. You said they were chrome but you have to know for sure they are chrome and not polished stainless or it will scratch. 0000 steel wool is also good for removing water spots from glass. I have used it on all kinds of chrome and it works great and will not harm the chrome provided you use 0000. I have even used 000 but I did not rub very hard and that worked too.

Use 0000 bronze wool, steel wool will leave micro fibers that can cause rust spots to appear no matter how well you think you've cleaned the surface...bronze won't rust and it won't scratch chrome or S/S.
I did the same thing and judicious use of acetone and broze wool cleaned my pipes up just fine.


Bronze wool is a bit pricey compared to steel wool but worth the $
Works good also on alum and other metal surfaces.

This happened to me a couple of times. I think I scrapped it off with a thin piece of wood, no scratches since my pipes are jet coated.

Get it HOT and wipe it off with ice water!! The temperature shock will release it easily....I had a damn plastic grocery bag get on my side pipe and this worked well!!

Also, in the event you get pine sap on your car.....isopropyl (rubbing) alcohol removes it pronto...no matter how long it has been there!!

Well I tried the hand cleaner, no luck. Can't try the ice as I took the radiator out this weekend to install a dual electric fan. Can't control the temperature from climbing out of the stratosphere. What a can of worms that is turning out to be. I'll try the compound next. Then I guess I'll try the chrome cleaner. I'm a little nervous to try any form of wool steel or brass.

0000 BRONZE wool will not harm chrome or S/S or jet-hot or ceramic coatings. It is softer than the materials

The dry ice I suggested will do the same thing as heating the pipes, then putting water on the spot... You might try it.

Pick up some "Never Dull" from your local auto parts house. I've never had anything stick to my pipes that I couldn't get off with it. It won't scratch and it's soaked with a softening agent. Give it a shot. It's super cheap.

I have chrome and the rubbing compound worked well with the car cover stains and discoloration from heat, human flesh burned on.

I had a black hefty bag go under my car once. Man that was a nightmare. I ended up letting it really get crispy and scraped it off gently with a razor blade, then hit it with rubbing compound.

Had the can of never dull sitting in the cabinet, gave it a try and I've managed to get most of it off. I think once I get the radiatiator back in tonight I'll get it good and hot and try the ice idea, even got rid of some of the blue at the inlet. Good stuff.

Am I to understand you are going to get the pipes real hot and then put ice on it to get the stain off??

Do you think you might crack the pipe(s) due to thermal expansion?

Maybe I did not understand what you were going to do.
