Good day members, I found a collection of records that have been in a very damp closet for years. Most have heavy mildew covering them. I have tried dishwasher solution to remove the mildew but this has little effect. I used a solution of 90% water, 10% bleach on home vinyl siding with success in the past but am hesitant to try on records. Any suggestions for safely removing mildew from records. Thanks in advance for feedback
