+ 1 for what rotarius wrote. I’ve occasionally tried to use Dust Off but sometimes something (condensation?) puts some liquid on the record. Doesn’t seem like a good idea.
A brush definitely works if dampened but must take care not to over wet it and thereby the record right before playing. To moisten very lightly a Hunt brush, I use an empty eye glass cleaner bottle from the eye doc’s office. Rinse it thoroughly and refill with a mix of distilled water and small amount of straight isopropyl alcohol (not rubbing alcohol). Spray that up in the air and hold the brush under the little cloud of mist it makes. Picks up dust without putting excessive liquid on the record.
