Do not use any kitchen or bathroom products to clean your records ever! That means Windex, soap, kitchen dish liquid, paper towels, etc etc. This stuff is a record killer. Windex can make a record look clean but give it the "Crackles".
To clean a record you need nothing but distilled water and a fruit cleaning brush. Though a fruit cleaning brush can be used because the bristles won't hurt the record, I highly recommend getting a real record cleaning brush that can be used in water. Try www.Needledoctor.com.
Now soak the record in distilled water (buy at any drugstore) and clean with brush. Then use a dish drying rack to let dry. I don not recommended using l alcohol, but if you do, mix it 15% alcohol to 85% distilled water. Good luck
