I found that out on the first one I cleaned
and quickly adjusted my handling methods to suit them better
Luckily I practiced on one I didn't care about very much.
I was given a stack of 50s rock 78s that were extremely filthy from sitting in a basement for 40-50 years. It felt great to get them all cleaned up and put into new sleeves. I used a bit of very simple/pure (laundry) detergent and some vinegar in distilled water, then rinsed under the tap, with a final rinse of distilled water from a spray bottle. I made a DIY label protection system from peanut butter jar lids and a sheet of rubber, cut to size.
It all seemed to work really well, but I've still not played them to hear the results. Finally got around to getting a 78 stylus recently, so will be hearing them soon.
