After reading Use Wood Glue to Clean and Restore Old LPs, I just had to try it out on some of my unplayable records I've accumulated over time.
I started out with my Dad's old copy of Cream's Disraeli Gears, which I've cleaned thoroughly multiple times (with my special record cleaner recipe), repaired all the scratches manually by hand, and it still sounded pretty messy. I knew that even if this experiment didn't work out, it wouldn't have been that big of a loss.
The result was astounding. The record was playable for the first time in years, removing almost all noise generated from years of accumulating dust and debris in the record's crevices.
I moved on to something a little more treasured, which was the US Mono release of Jefferson Airplane's Surrealistic Pillow. While I've always loved the way "White Rabbit" sounds on this recording, at its peak on the record it is dissatisfying when shrouded in the static white noise cluttering the recording. After the wood glue treatment, it sounded perfect, beautiful, powerful, and all those other adjectives that express awesomeness.
I've started going through my Sinatra collection applying the glue in the evening and then peeling off the plasticized layer in the morning. It's the best record cleaning solution I've come across, for its thoroughness, time efficiency and cost efficiency. I highly recommend it to anyone out there looking to restore their LP collection.
