I spent $1000 and got a large UVC sterilization cabinet, it can fit 40 or so frames in it and kills covid in 45 seconds, though I usually run it for 10-15 minutes, easy peasy. Kills MRSA, TB, fungus also. If people are nervous I will gladly place any frames they want into it pre them trying it on. Was a pain in the *** to get one, but glad I did. Probably more glad for the MRSA, TB, Fungus stuff than the covid which dies off pretty fast anyway.
I used alcohol at first while I waited for this to come in but I am not comfortable spraying and wiping down $500 frames 5 times a day with rubbing alcohol, it will begin to damage them for certain.
