Hi all,
After years of experimenting with the "best" way to remove at least 50+ years of crap in the grooves of 78s, I think I have found the best method! The method I am about to describe removes every trace of dirt, dust and similar contaminants from your records and kills any sort of that mildew/mold that you so often find on the early shellac 78s. Plus, it gives 78s of all materials a shiny surface, buffed labels, and enhanced playback; more so than what cleaning with simple soap and water can do.
STEPS:
A.) Clean the record with warm water and mild soap.
B.) Dry the record off with a towel and let stand for 8-12 hours to completely dry.
C.) Play both sides of the record to ensure that there are no skips or tiny particles stuck in the groove that the soap and water did not remove.
D.) Apply a moderate amount of Old English lemon oil all over the record with a soft clean cloth. Now before everyone here has a heart attack at the thought of applying it to your 78s, just read on because you don't actually have to play your lemon oil-soaked record. Apply it in a circular motion, going with the grooves. Think of this step as buffing the record, because you are bringing all the remaining contaminants that soap and water didn't remove to the surface and polishing the record surface too. (Note: I recommend putting a sheet or two of paper towels on both sides of the record to act as an ersatz sleeve, because the lemon oil WILL soak through if you use the original paper sleeve that you used to previously store the record.)
E.) After 24-48 hours have passed, you will notice that almost all of the lemon oil has disappeared off of the record's surface or has been reduced to a very fine coating. At this step, clean the record again with soap and warm water to remove all traces of the lemon oil from the record.
F. ) As with the first time you used soap and water to clean it, dry the record off with a towel and let stand for 8-12 hours to completely dry.
G.) At this step, the cleaning is complete! You now have a record that is as clean as possible, and as we all know, the cleaner a record is the better it will sound, protect against excess wear and the better it will look. You may now put the record back in its paper sleeve or put it on your turntable and prepare to be blown away by the super-great fidelity and rich sound!
I have used this method on dozens of records-even ones worth over $100-and have always gotten great results and the finished product of a record that looks and plays like it was 20-30 years younger! It doesn't remove groove wear, scratches, or label tears but it does get rid of unsightly scuffs and leaves your records as shiny as a mirror. (You can also use this method to clean vinyl, but as vinyl isn't as porous as shellac, you must use only minute amounts of lemon oil; otherwise it will never fully wash out. This method is NOT approved for cylinder records of any material, Diamond Discs, Pathes, or acetates!!)
Hope this helps and be sure to share if this method worked well for you! Take care and happy collecting!
