What do you do when nothing seems to get LP clean?

I've been thinking of trying some of the more exotic/expensive record cleaning fluids. However, it seems from this thread that there is some concern about the long term effects of the chemicals, enzymes, whatever that are in these cleaners. Another poster also expressed concerns about tap water.

I use a drop of mild ivory dishsoap, tapwater, and a carbon fiber brush to scrub my records. I then rise them off quickly and thouroughly with the shower spray on the tap, and then rise again with distilled water. I've thought about a vacuum, but the rinse with the shower seems to flush the debris out and off the records. I let them air dry in the dish rack. They seem to dry clean - if there are any drops of water left on them, I dab them, not wipe them, off with a paper or cloth towel. I've been doing this for quite some time and it seems to work well, no problems yet. Many records show a marked improvement in sound quality afterwards, especially since I started using the carbon fiber brush. Others, however, sound bad no matter what because they are just poor recordings. In the end, for now I have a little more trust in TAP water which I can drink.

Gee whiz. Irrational? I never said I know the "be all and end all of record cleaning." I simply stated that some posters had expressed concerns about the chemicals whatever in what I understand to be something more than my simple inexpensive way to clean records. I also never dissed any specific product and if anyone took it that way, sorry. But, I have heard/read that some of these products are pricey. If that's not true, great. I was, I guess, joining the discussion, admittedly probably over my head. However, I just wanted to share my personal experience. I'm not criticizing anyone's product, I haven't even tried them. I hope they work well, good for you. I did attempt to just share my experience. I too hope my vinyl doesn't melt or slide off my platter. I will still say that I've had good results with my method. Maybe I'm totally wrong. You know I'm nuts too. Like I posted, I've been thinking of trying the stuff. It's just when posters who I think have more vinyl experinece than I have questions about a cleaning fluid, then I wonder too. Peace.
