FinishPly™ can be cleaned with a solution of mild detergent (dishwashing soap works well) and water. For a thorough cleaning, remove all lugs and hardware from the shell. Here at the Workshop, we use Music Nomad Drum Detailer during final assembly (for Lacquer and FinishPly only) to give our drums that extra shine. You can order some for yourself at: https://www.musicnomadcare.com/Products/Drum-Detailer/
