Use plenty of solution and really get the record wet while being very, very careful to keep the solution off of the record label, as it will cause the paper label to “rise” or stain the label, etc, and it will never look like new again.
Apply the Cleaning Solution to a Cloth or Record Preener
The best way to apply the cleaning solution is to apply it to the cleaning device that you are going to use, such as a soft cloth, record preener (brush), etc. I recommend a very soft, clean cotton material such as a baby’s diaper (old school, washable type).
