Seems over priced to me for a record vac.
I made my own Record Vac by using a $50 shop vac,Vinyl Vac wand, lazy Susan , old platter for all around $100. For another $100 I got the Vevor UC. I only use distilled (actually RO) water in my UC. Stopped using ISO, Photo FLO, TERG in my cleaning. They all seemed to leave a small amount of residue behind.
For really dirty records I use MOFI Enzyme Cleaner with a rise and vac afterwards. Followed by 10 min in UC with just RO water. Then rinse and vac again. Clean with no residue. Best results for me so far.
