Biokleen Bac Out cleaner

Enzyme cleaners do not dissolve dirt, grease, and stains unless the dirt, grease, and stains are of biological origin. If they're not you're wasting your time and money.

Opalchip should really learn some basic biochemistry before making his claims about a product called MoldZyme. If the ingredients are as he reports, and if the "fermented vegetable matter" in fact contains active enzymes after the fermentation process is complete, there will be little if any active enzyme present after the surfactant is added. Surfactants in significant concentration deactivate enzymes, and deactivated enzymes are useless. They do nothing to anything. Likewise, if Almandog is adding the "Biokleen Bac Out Cleaner" to his otherwise sensible witches' brew, all he is doing is destroying any enzymatic activity which might have originally been present in the product. It's the other ingredients that are doing the cleaning.

The only activity associated with some of these enzyme-based cleaners is in the bank accounts of the people who sell them to gullible audiophiles.

In response to Opalchip - indeed I am aware of the difference between ionic and non-ionic detergents, and indeed I have done the research, but in laboratories rather than by Googling elementary textbooks. I am also aware of the effect of cmc on the behaviour of enzymes in the presence of neutral surfactants, which seems to have eluded the author(s) of your books. I am not aware of the type of surfactant present in MoldZyme - I hope it is neutral since ionic surfactants have no place in LP cleaning in my view. There are some popular proprietary cleaners which break this rule, so nothing would surprise me.

Neither you nor your books address the crucial question however. How do enzymatic cleaners remove non-biological crud?
