I use purpose made watch cleaning fluids and rinse fluids. I find these to be the most effective. In any case I find properly disassembly and cleaning of the 3rd and escape shock assemblies to be an indispensable step. In my experience Japanese movements are especially sensitive to proper cleaning and lubrication so you'll want to get every nook and crany. I do achieve around 300 amplitude with these but only after very meticulous cleaning and precise oiling.
