I should point out that all of the above instructions pertain to standard, shellac-based 78s. If you have any "thick" Edison diamond disc records -- http://www.gracyk.com/diamonddisc.shtml -- NEVER apply water to them since water will dissolve the center core of the record. The condensite surfaces of these records should only be cleaned with alcohol. (Along this line, NEVER use alcohol on a shellac based 78.)
Thanks for the clarification!
One more question regarding the drying process - will resting the discs on a typical rubber-coated dish-rack affect the grooves (possibly ruin them)?
My questions might seem slightly paranoid in their concern because I have about 40 discs that are extremely rare and plan on digitizing them - thus wanting to get the cleanest, best sound out of them.
