Used the original Discwasher religiously from the early 70's till 1985 or so when I went down the CD rabbit hole and stored my records away in a closet. Reading all these threads about vinyl sounding better on Gon got me a get a B&O turntable to cautiously dip my toe back in round 2005. Found my stored for 20 years records to sound great, no clicks and pops or crackling.
So I resumed using a vintage one off ebay ( I'm told the new ones don't have curved bristles and don't work as well). On the fence about going ultrasonic mostly due to price.
