Just a thought; why not wash your records in the kitchen sink with a couple of drops of washing-up liquid?
I think it might have been Percy Wilson who suggested this idea in a 1960’s copy of Hi Fi News. I have used a variation of his method over the years and find that often virtually unplayable records can become pretty good.
‘For the perfect wash:’
1) Find an old Watts ‘Disk Preener’ - one of the current ‘Decca type’ carbon fibre brushes might also work.
2) Fill the sink with about 4 Inches of clean warm (but not hot) water.
3) Put a couple of drops of washing up liquid in the water to reduce the surface tension.
4) Throw in the Preener
5) Place the record vertically into the water and rub the Preener around the record working the water well into the groves but don’t rub the label.
6) Place the wet record onto a flat surface covered with a clean absorbent cloth. These days I use sheets of kitchen paper.
7) Rub a pad of kitchen paper around and around the groves to remove most of the water.
8) Leave for a few minutes to dry before playing.
Sorry if this is old hat and has been discussed here before.
Cheers
