Biokleen Bac Out cleaner

Has anyone try using the Biokleen Bac Out cleaner or their General Purpose cleaner to clean records?
The Biokleen Bac Out cleaner have enzymes in it to dissolve dirt, grease, stains. I am considering to give it a try on some discarded records at first to see the results. Here is what I plan to do: buy a bottle of Biokleen Bac out cleaner and a bottle of Biokleen general purpose cleaner. Mix some Biokleen general purpose cleaner with distilled water. Then:

1. Steam clean the record first
2. wash the record with the Biokleen Bac Out cleaner (with Enzymes)
3. Wash the record again with the Biokleen general purpose cleaner (mixed with distilled water)
3. Use my record cleaning machine to to vacuum the record.

Does anyone have any comments?
I will post the results.

Maclogan,
You have to be right, after all you have a back ground in chemistry....

Giving some thought to your comment above including else where here on Audiogon relating to this subject.
The results using active enzyme base cleaners for vinyl, have to be imaginary.

Oh man....I feel SO embarrassed being suckered like this by Lloyd Walker.
It's too late for me to return the Prelude kit and Step 4 rinse for a full refund....

Well, live and learn.

Here is a formula that I can recommend and it is dirt cheap, easy to make and easy to remove.

900ml distilled water
89 ml of Isopropyl alcohol
1 or 2 ml of Triton X-100

I got the X-100 from Thechemistrystore.com, like $10/qt.

To rinse I can recommend this mixture

990 ml distilled water
10 ml isopropyl alcohol

The problem with all the "witch's brews" is the added ingredients in home cleaning products, like colorings or fragrances etc. and just not knowing what you are working with.

Hope this helps.

Someone above here doesn't really know his MacStuff or bother to research it. First off - Nonionic surfactants (which is the ONLY type in MoldZyme) absolutely DO NOT degrade enzymes. Do some research and get back to us. I can cite at least 10 studies that show, in fact, the BENEFICIAL effect of nonionic surfactants on enzymatic action. Here's a start:

2nd - It just plain works. I'm not influenced by Audiophile voodoo (and this is not marketed to audiophiles). I have experimented with many things, and this is the best I've found that is easily store bought. Ken's homebrew is also excellent (although I personally would up the Triton to around 3 or 4 ml) and because X-100 is nonionic it would also be improved with the addition of a protease/lipase mixture.

Moldzyme BTW has no added colors, fragrances, etc.

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?
