WD 40 to remove scratches on vinyl !

Spray WD-40 on brass and see what happens after a week or two. WD-40 is corrosive to some metal; which might not be good for yout cartridge.

I have found the best product for cleaning is called "Last"
Do not know if it is still made.
I simply use a little warm water on a lint free Clothe.

Doh!

Don't do it.

There are two products from LAST. LAST lubricant/preservative and a cleaner called All-Purpose Cleaner.

Last Record Cleaner is still available from The Last Factory, as well as some audio retailers.  It is expensive, but works to remove all the grit and grain of new or (some) original pressings.  Most of my records are already "Last'd" (I have been using it since the late '60's).  But it DOES NOT remove scratches.  So far as I know nothing does.
