I bought my LG100 secondhand and with a VFG cleaning kit I put over 25 felts (and paste) through it, and they were still coming out black
So I left it at that. It did tighten the groups.
I now clean it every half a tin (250ish) But I still never get the felts properly clean?
Should I keep going until they are coming out completely clean? If so, I need to buy a lot more felts!
