I use MoldZyme for problems where I suspect noise due to mildew in the grooves. First off - the only ingredients in MoldZyme are: Water, Fermented Vegetable Matter (the enzymes), and Natural Surfactants. I have let it soak on lp's for hours and it has not caused damage.
The problem with mildew is that it may adhere to the vinyl more tenaciously than dust or grease. So a typical alcohol/surfactant combo cleaner often doesn't work on it - that's when I suspect there is a mold issue.
If after vigorous cleaning with Disk Doctor cleaner I still have surface noise on a mint looking lp, I pull out the MoldZyme. Spray it on very liberally and let it soak for 10 minutes or more, then I use the DD pads as normal, rinse, then re-clean with the usual DD fluid. This often completely eliminates the problems. I sometimes wonder why not just use the MoldZyme to start with - it's extremely effective and much cheaper than "audiophile fluid".
