I have found every excuse not to do this for fear of never being able to put humpty dumpty back together again. I have done this on larger Alps slide selector switches in a Rondo3000 with good results, but not these. This type of cleaning and polishing ( with a dremel-type rotary tool and mini polishing drum attachment) of the contacts in the selector switches will make all the difference between a good restoration and a fantastic one! You will reap the sonic benefits of this, goes head and shoulders above contact spray cleaners which have limitations. I have cleaned and listened via both methods...spray and then strip/clean and treble was more sparkly and overall clearer sound as compared to just a spray-clean, maybe slightly less attenuation with all the oxide and dirt/stains polished out, but havnt measured that but there was an improvement in sonics. Well done Sir! :thumbs:</blockquote>
