This special spray from Nagaoka is specifically developed to prevent microbial activity on the record surface. Especially useful in humid environments and for records being stored in paper sleeves. This spray will prevent fungus and/or mold from building up on your record. To use, spray from about 1' distance on the record surface and wipe it clean with the Nagaoka Record Cleaner Brush. Its a fast dry product but check if the record is dry before storing!
