The KL uses blowers to dry the record ... this is just as bad, maybe worse than plain air drying in a rack. Any contaminants dissolved in the water remain on the record as water evaporates. This is the main reason I did not get one ...
It may sound bad on paper, but it works fantastic in practice. It is amazing how clean an LP is after coming out of one of these machines.
The set up is also awkward with a tank on the floor.
I have the self-contained cln-lp200 model. It offers one-button convenience that makes record cleaning as simple as pie.
