Slaw,
What fluid do you have in the degritter?
I have the second tank so I can use the rinse feature. You might want to get one for your final rinse, it's very convenient.
Got a link for Walker?
Tergikleen or AIVS formula 15?
I've got both fluids here that I can use for pre cleaning.
I have 2 spin clean machines one is for washing and the other one is just for rinsing the pre-cleaner off the record before going into the Degritter ultrasonic.
The Tergikleen is a little more convenient as it's a concentrate that I can mix up and put into Spin Clean #1. The AI fluid is less fun to use since i have to put the record on a work mat and work the fluid in with a MoFi brush before rinsing it off.
I'm wondering if anyone here has found that one fluid works better than the other? I haven't been through enough records to pick out the difference yet.
