Just a dry cloth. Chrome does not dull. It just gets fingerprints, or actually rusts (which cannot be "polished" off). If you have silver colored hardware that has actually dulled/hazed, then it is nickel plated, not chrome plated. In that case, try a fine metal polish, like Maas.
Mayones guitars are all Polish.
I don't know those guys personally but I do have many Polish friends and I think they would not use the alcohol for cleaning the guitar.
Instead they would drink all the alcohol with you and end up driving around the block with the guitar attached to the rear of the car, removing your fear of having a scratch on it forever.
On my side, I've been using a Dunlop formula #whatever kit for ages to wipe my particles off the guitar. Dunlop formula #whatever is not nice to drink. I'd rather have alcohol with my pragmatic Polish fellows.
Personally, I'm with your Polish friends. One of the reasons I never buy new. And btw, I'm not trying to clean the guitar, just the chrome. I'm going to sell it or trade it.
