cleaning liquid for LPs

I have been very satisfied with Disc Doctor cleaning fluids.  Not terrible expensive, but really effective.

DON'T BE FOOLED INTO USING ANY ALCOHOL-BASED CLEANERS.  They can leach out some of the softeners required to help a record recover from use.

I use nitty gritty enzyme cleaners with my machine

I've been using the L'Art du Son fluid.  It's excellent.  After it's gone, I'm going to try the Audio Intelligent #6 one step.
