There has been a lot of discussion about the need or desirability of a DW rinse cycle. One guy claims he hears an improvement with a rinse. One thing to keep in mind is that the rinse water gets contaminated. I just had a thought, maybe after many rinse cycles, the rinse water could be used as the primary cleaning water - with the addition of more cleaning solution. I considered getting a second tank but they want a fortune for that piece of plastic! For rinsing, a dedicated second tank would be nice since you could run a clean cycle with no dry and then rinse and dry. This would save record handling and fan time.
I clean my stylus after every full record with a DS audio ST-50 cleaning pad. It usually has some white residue on the stylus -- some records do not though. It may depend on when in the tank-use cycle the record gets cleaned. I've settled on no more than 30 cleans per tank. My records visually look clean already but given how the filter gets yellower and yellower as I go through the tanks, there is obviously dirt in the cleaning water.
I've been systematically cleaning my entire collection with a Heavy cycle. I'm over 600 and counting. Once I get through them all I think my Degritter will go to occasional use mode.
I think the Tergitol is an improvement over the Degritter solution but it is only available from one supplier in the US. With shipping, you'll pay almost $40 for a pint -- which will last for probably 1 million records at the rate it's used!
