Using this record weight is easy. For 12 - inch records, just place the flat side of the weight on top of the record. When you're playing a 7 - inch large - hole record, use the side with the 45 adapter. As for maintenance, you can use a soft, dry cloth to wipe it clean. Keep it away from harsh chemicals and extreme temperatures. Don't drop it as it might damage the brass. If you have the anodized black model, be a bit more careful while cleaning to avoid scratching the finish.
