What happened to Discwasher?

So I went to get a refill of D4 fluid, which I use to clean records before I transcribe them for more convenient access. No more around. Unless someone has old stock? I cannot justify a 2000$ record cleaning machine for a handful of albums to burn onto a car CD. So does anyone have a substitute cleaning fluid, or know the secret formula for D4 fluid? Guess Discwasher bit the dust in the middle of a vinyl resurgance? Hmmmm. Thanks!
