I use to follow Wigwam Jones method of cleaning records, and it did work. The problem was, energy. At 65+, I don't have a lot and standing over a sink , scrubbing 10-12 records at a time, killed my back. Came Christmas, I invested in a KAB RCM. What a difference. I was worth every cent of the $170. Yes, I have to invest in cleaning solutions, and yes, there are lots of DIY solutions out there, but they better be blessed by the Audiophile Gods. I noise level of my hand washed records dropped considerably, but using the RCM, I know that the life is being sucked out of the grooves, leaving wonderful music. I usually buy 3-5 records at a time, and after running them through the RCM, they are ready to play immediately. I do believe, fidelity increases with a deep cleaning.
