I often find new records that are dirty right out the jacket especially if they have paper sleeves. Always clean a new record as most have a film on them that cleaning will remove. Never blow the visible debris off your record with air from your mouth as this will leave minute particles of moisture that will harden and cause problems. And do not forget to keep your turntable platter or mat clean so that dust or debris is not transferred to your records especially if you use a record clamp.
