DIY record cleaning solution recipe needed


Do you make your own cleaning solution? Would denatured water and isopropanol work? Is that bad for vinyl? I'm using a cheapo Discwasher brush with D4 fluid. I want to make my own fluid! Thanks for any info.

I have a question for you a response you made regarding a ARC sp-5. You mentioned your sp-6 that you had modified with the protective circuitry removed. I have a sp-6 paired with an ARC d-110b. Curious how removing the protective circuit affects the sound. Thanks, - Charles

Hammy, for Disc Washer brush use get a bottle of Benzalkonium Chloride 1:750 and mix one part BAK to 4 parts distilled water.
