I'm not sure about your unit but no need to repeat the cleaning with my Audio Desk Systeme, as long as you handle them correctly and keep them clean. I put mine in new record sleeves once they are cleaned.
One cleaning is enough unless the record was exposed to things like cigarette smoke or cooking fumes which are more stubborn to get off. The addition of alcohol at 1% helps in that regard. Record that are clean, stored properly and played properly will not have to be cleaned again except for a sweep to remove incidental dust.
