On another forum, one of the gurus told a tale of how to get the most from your Spin Clean. He went 20-30 times in each direction. Changing it up it up half way as the bristles on the brush get used to going in one direction. So 10-15 right, 10-15 left, 10-15 right, and 10-15 left. You will get a lot more junk out this way. Other Spin Clean gurus chimed in on this post. One poster used an eye dropper to place the capful of solution over the entire surface of the pads claiming that the lead in grooves got much cleaner this way. With this extra cleaning, you will be lucky to get more than a dozen records clean per bath.
I have incorporated these practices in my own Spin Clean regimens. I also wash the brushes and cloths in hot water with a capful of bleach every once and a while. This helped. I also purchased a file holder from an office supply place to hold the records while they dry. If you have another set of brushes, dump the dirty water out of the basin and give it a quick rinse. Then replace the dirty old brushes with the clean ones and refill the basin with distilled or deionized water only. Now give each recently cleaned record a rinse with the traditional 3 right and 3 left procedure. The rinsing will reduce the number of snaps and pops significantly.
I own a RCM. But I still use the Spin Clean to knock the bark off’em every time.
The analog guru who got me onto this procedure has to have one of the nicest systems anywhere. 7 figures worth. Yet this gentleman gives out expert advice freely and routinely. He should be an inspiration to us all.
