Which cleaning solution do you use in you RCM?

I love the Audio Intelligent the best so far, over RRL and MOFI. It's just made my records quieter. Can't comment on the static factor. I use the #15 and then their water rinse. They do have a 3 step, but that and the Walker 4 step would prevent me from cleaning at all.
One thing, do not put anything in your path that prevents you from using your RCM, or table for that matter. I learned that from the great Gene Rubin years ago.

I'm sure the walker products are good, but I'm not doing a 4 step with anyone. For now, I'll use the best 2 step I've found so far, the AI.

Hiendmuse, I think everyone would prefer a one step method, but without rinsing you're doing your records no good at all. I know full well--me and several of my friends used RRL and MoFi for years without knowing we had to rinse. What a difference it makes.
