Help needed with mij CW4 grille

[Flevoman]

Someone who can help me with my issue. I bought the CW4 over a year ago and immediately removed the grilles, storing them in the attic. Now, as these speakers are going to my brother in two weeks, I retrieve the grilles from the attic and notice very clear markings where the magnets from the other grille were in contact with the front. It seems like the gold wires have reacted somehow with the magnets from the other grille. No idea what to do about it. Using a mild soap doesn't do anything, and I'm hesitant to use chemicals. Any idea how this could happen and what I can do to remove these marks? I have a feeling the gold wires contain a metal that has oxidized. Also, I'm unsure if I can order a replacement grille if the stains are unremovable.

What's this "other grille" you speak of? Did you store them in the attic attached to a different pair of Cornwalls?

[Flevoman]

No, I placed both grills against each other and stored them like that. The magnets of one grill were against the front of the other grill for over a year, resulting in this outcome.

are you  the original owner and are you still covered by the 10 years warranty ?

[Flevoman]

i bought them from a hifi shop . they where used for a demo but still new so i am the first owner.
i have no idea about warranty , never thought i would need that 😶

I don't see this as a problem that Klipsch is responsible for, I'd call it bad luck. The safest place for the grills of any speaker would be on the speaker, take them off at your own responsibility.

I would call Klipsch and find out the cost of (1) new grill covering, and or frame and fabric.  From your description it sounds as if only one was affected.  I would think that any chemical cleaner would make the stain run down the fabric only making it look worse.

Hello again! Would contact Klipsch just to gain any information regarding the situation. Although not covered, still would want to make aware of. Or if from local seller, the same.

Something may come of it, or not.

Thanks!

[Flevoman]

Thx for the help. 

I can contact Klipsch to see if I can order a new grille. 

Probably this will not be an issue. 

But I was hoping someone could give me a tip to remove these stains.

 

[Ceptorman]

I would try to clean the stains, it can only help. 

Or re-cover them with new fabric.

 

Try a few different types of cleaners, wet the fabric, dab it on and rinse. You might get a response.

What happens if the cleaner that Klipsch approves makes it worse? 

[Flevoman]

Any idea what kind of material is used for the gold wire? 

I can't see if it's plastic or something with some kind of metal. 

For some reason I have the idea it is oxidized. 

[KT88]

That is a good question. Oxidation was also my thought. Possibly a galvanic interaction between two different metals. Similar to a Landrover Defender, when it swells in the places where the aluminium of the doors, mudguards etc is in contact with the steel ladder frame. Perhaps there is a metal component in the golden threads that came into contact with the magnets. If this is the case, cleaning will hardly help.

[KT88]

If the mesh cannot be saved anyway, perhaps try using citric acid or baking powder dissolved in water. Old household remedies for rusty aluminium. Of course, I don't know what the covering material is made of, but it could be vapour-deposited metal on the fabric or metal strips like tinsel on a Christmas tree, similar to those used on Fender guitar amps.

Heat from the attic cause bleed thru from magnets on one grille to the other? Best bet would be to just order new grilles from klipsch. Can try cleaners as suggested by kt88, since the stains are there regardless.
