I have a bottle of Realistic professional anti-static record cleaner fluid to be used with my discwasher record brush. I used the fluid last 35-40 years ago, and it seems about 1/2-2/3 full. Is it still good?
Will the brush, without fluid, work well enough?
If the bottle is no good, is there a DIY mixture I could make up? If not, where would I get fluid like this again?
