Re: [ARSCLIST] White haze on older LPs -- cure??
They could be pressing defects from the factory. I have a number of Mercury
jazz titles with this hazy appearance that makes a constant hiss/crackle. I
believe it was a problem with Mercury's presses. I may be wrong on this,
but when they switched from shellac to vinylite, they had to reduce the heat
on the machines. If they didn't, the vinyl would cook. Just my theory on
that.

Subject: [ARSCLIST] White haze on older LPs -- cure??
Hi All:
I have here a couple of mid-50's mono LPs, excellent condition as far as
scratches and grit but they have that dull white-ish haze, which seems to
make the vinyl hiss when it's played. Kind of like tape hiss, but less
full-spectrum. Not swish-hiss, which seems to happen when this film
doesn't uniformly cover the whole record surface. I think this white-gray
substance might be leached out of plastic inner sleeves, but why only on
one side of the records? VPI fluid doesn't remove the substance but does
remove any crud from the grooves because the records play beautifully
except for the hiss -- not a single tick/pop and no groove crackle.
Any way to remove this or is it now part of the vinyl?
