I too bought a replacement bottle of 'D4' from Amazon. Such a HUGE disappointment! The D3 fluid worked really well and was great at picking up everything from tiny lint srtands to hair (eye-lashes) and general detritus. The new stuff has this lovely 'funky' odor (one I have never smelled any before) and simply didnt do the job as far as picking up fine particulates. I ended up buying distilled water, iso-alcohol (I use it to clean the contacts on my electronics connections any way). Didnt try the detergent, but I think I will give that a shot here shortly.
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!
