Retailers may place security stickers or price tags on the outside of CD cases. Although the stickers are usually fairly easy to peel off, they may leave behind a sticky adhesive that's not as easy to remove. If not removed, the residue can leave the CD case looking dirty and attract dirt and dust. Prior to cleaning off this residue, remove the CD and booklet from the case to ensure they don't become damaged by any water that may seep in.
Open the CD case to remove the CD, and slide the inserts and booklets out.
Dab a cotton swab in baby oil, and rub the baby oil onto the sticker adhesive. Alternatively, you can apply a commercially sold adhesive remover.
Allow the oil or adhesive remover to work into the adhesive for five to 10 minutes. The thicker the adhesive, the longer it should soak.
Dampen a soft cloth in warm tap water. Wipe away the oil and adhesive residue. Repeat the process until all residue is removed.
Fill a small bowl with warm water and a squirt of liquid dish soap. Dip a soft cloth in the soapy water, and wipe the cloth onto the CD case to clean off all remaining oil residue and adhesive residue. Dampen a cloth in cool water, and wipe down the CD case to remove all soap residue. Dry the case with a soft cloth or towel to prevent water spots from forming.
