David, I'd steam the hammers, it's pretty effective and very quick. I'd use a damp cloth and hammer iron heated to about 175 degrees. Multiple passes will bring the tone down, ironing after will settle it. Then needle individual hammers as needed. If you want to add a drop or two of fabric softener to the water you use on the linen cloth, it will accelerate the process. I find the use of fabric softener solutions on hammers harder to control so I don't use them.

I've got a customer with an old upright that someone put some real rocks on and there's no way to needle them down. Tried the alcohol and water route with limited success, going to plan B before I set the explosives. David Love www.davidlovepianos.com
