Used speakers: Cleaning tips?

Soft brush would be fine for the cones and try some of the better furniture cleaners and polish out there. Really not a hard task and very enjoyable.

I have been using Pledge Dust and Allergen brand dry cloths. They come in a plastic bag like pak of 16 and claim to "grab and remove dust and allergens, a dry eloctrostatic cloth" They have been easier and more effective than using a more conventional cloth and spray product. They leave no chemical residue -just work magnetic like, on dust. I shake them off after use and they last for a few days without problems. I have even used them on a record rather than a brush. I can't remember the price but I will not be without these from now on, very handy.

Why thank you!
Will get some Formby's, Pledge cloths and a soft brush for cones is a great idea!

The Murphy's Oil Soap is a wonderful cleaner. I bought some used speakers a bit ago and tried cleaning them first with Kleen Gaurd. The Kleen Gaurd was making matters worse. My wife got out the Murphy's Oil Soap; what a difference.

I have a pair of the original Linn SARA speakers in real Rosewood and tried just about everything out there. Some things worked okay and others didn't really seem to do anything, (good or bad). Then I tried the Murphy's Oil Soap with ORANGE oil and they look like new now. WONDERFUL stuff.
