One option is to have your cleaner in an enclosure. I have one for my Klaudio cleaner and it has the added benefit of noise reduction.
Room Dust and Records
I'm a new Degritter user and upon cleaning new records and examining the record with a tactical flashlight, I can see dust on the record prior to removing it from the Degritter. I assume that this is dust from the air.
I have a dedicated room where I have removed paper product and use a large HEPA air filter and vacuum. I also keep humidity around 55%. What else can I do to mitigate dust?
