My cleaning experience suggests oily residue is why dust won’t simply “blow” off a record. Imo the value of detergent and surfactants is not up for argument; as is the value of thorough rinsing. FWIW I have a significant collection accumulated over 50 years. I have found the Discwasher brush and the LAST products in particular very effective. I don’t wish to generate any comments from this,but, I feel records are somewhat like lovely feminine women with sweet personalities — they are tougher than you’d think.
How much isopropanol is effective but safe for viny?
I make my own cleaning fluid using isopropanol and distilled water but am aware that some think IPA is not good for vinyl. Since the contact time is quite limited I think that it is probably OK to use a small amount as a solvent for greasy contaminants. What do you thing know is a safe level? 25 percent, 10 per Cent , or some other level??
