Cleaning black coated exhaust

I have the black QD pipes on my F3. I recently cleaned them with some metal polish. They came out looking good but as soon as I ran the engine the areas I polished turned white and started to haze.

What do you guys suggest to clean up the matte black areas of the exhaust?

Oily rag while exhaust is cold, obviously not too oily

I have a feeling the polish is now baked into the exhaust and there is nothing you can do. Oil will make them look good until you start it up again

WD 40 seems to be the fix-all for that sort of thing.

I use stainless steel cleaner, in spray or wipes. The same stuff you would use to clean stainless steel appliances. WD-40 works good too, but I was always concerned that since its a solvent of sorts, it might eventually ruin the finish.

The guys at QD said just soap and water. They also said not to use WD40 as it would ruin the finish. Hopefully I can get the old polish off. Seems crazy that polish that was specifically marketed as exhaust polish would bake like that. Should have got the silver pipes.

Did it happen to say for use on Chrome or metallic surfaces? The only product I have seen specifically for polishing exhaust is made by Borla and it says "Quickly cuts through layers of dulling oxides to restore original finish
Adds tarnish protection
Can be used on cars, trucks, motorcycles and boats, or other household and shop cleaning projects
Cleans and polishes chrome, copper, brass, aluminum and other metallic surfaces"

I hope not but I kind of think your screwed, it`s been baked (burnt) on just like what happens to food in an overheated pan.

Realizing that the rep said it would ruin the finish...your finish is already screwed.
That being said, use a product designed to de-grease/de-wax/and de-silicone paint prior to sanding.
It is usually called prep-wipe or pre-sanding prep or something of that nature.
These products are designed to remove surface contaminates without damaging the underlying surface.
Follow the instructions.

FWIW, water is also a solvent.

But not something that`s been baked on at 500 degrees
