Just a quick follow-up to my post about 80% H20/20%IPA being capable of removing static charge from an insulator. The reason this works and plain water does not has to do with 'wetting' - the difference between the fluid surface tension and the critical surface tension of the insulator. The critical surface tension for Teflon is ~19 dynes/cm (~one half of PVC) and
80% H20/20%IPA surface tension is 30 dynes/cm - low enough to 'wet' the Teflon. Given these results, a 90% H20/10%IPA with surface tension of 40 dynes/cm would be more than adequate to remove static from a PVC record that is ~38 dynes/cm. Just remember that for water-IPA solutions with >2% IPA - the vapors are flammable.
Options for ridding records of static electricity
I am getting back into vinyl, listening to “garage sale” finds and also new albums that I have been picking up. I have a nice old Linn Sondek LP12 with the felt mat. Every time I go to remove a record from the spindle or flip the record, static electricity grabs the felt mat and it sticks like a magnet. I have to very carefully flip the felt mat at the corner with my finger but one of these times I’m going to slip and smudge or scratch a record.
I’ve seen the “Milty Zerostat” and seem to remember this product from back in the day. I see that it is still made and there is one eBay vendor that has them for $77. Is this my best bet? I thought Michael Fremor talked about these in one of his videos.
Are there other products I should look at to reduce static electricity on my records? Thanks for any help you can give.
