The acetone probably won't make them brighter. I have used it to make the felt denser overall adding a bit of power but mostly underneath. I would try pounding the hammer with a small hammer and polish the top of the hammer down to 600 grit sandpaper first.

I ironed the 10 or so hammers out and they are brighter. There are only two notes that need more drastic measure. The lady wants those brighter, so I am going to try some acetone on them. Again thank you! Julia Gottshall Reading, PA -------------- next part -------------- An HTML attachment was scrubbed...
