Title: Endozime
Post by: orthobiz on 4 Sep 2009, 01:41 am
As some of you may know, I'm an orthopaedic surgeon. I have been using a product called Endozime for the past year with good results. They buy this stuff by the gallon at our hospital and splash it all over to dissolve blood and goo and stuff (doesn't work on bone!).

To digress a little bit, we were always taught that the orthopaedic market was too small to make the development of customized stainless steel just for bony application. So we were "stuck" with Type 316L, a good industrial grade stainless.

So I thought maybe the same is true of vinyl enzyme preparations. I mean, how many gallons of this stuff can audiophools buy to make it worthwhile for industry to invent a whole new class of cleaners for us? Is it possible that the stuff we use in the hospital is just as effective or, could the hospital type stuff actually contain the main ingredients of the expensive audio stuff?

Anyway, I checked out the Endozime and found that they use it to soak the most delicate instruments we have, some of which are "plastic" coated, such as eye instruments and colonscopes and the like. It has protease and amylase, powerful protein and starch enzymes that "Will not harm any metals, plastic, rubber or corrugated tubing." I think vinyl records would fall into the grouping!

I brought a small bottle home and have been using it to good effect ever since. Further info from the website:

"Endozime is a dual enzymatic cleaner that removes blood, protein, mucous, vomit and fecal matter. This formulation of Protease and Amylase enzymes with buffers and surfactants is perfect for all flexible and rigid scopes and instruments. Endozime? will solve any problem with clogged channels, sticky biopsy forceps or clouded lenses, leaving both scopes and instruments free of any unpleasant odors and baked-on blood." OK you 50-somethings, I don't know how well it works on resins and I'm sure it doesn't dissolve seeds!!!!!

All it takes is an ounce added to water (I use reverse osmosis stuff from my kitchen, M Fremer once said it was OK so I believed him) and you have an pint or quart of enzyme (it is supposed to be really dilute but I make it stronger).

If anyone is interested in trying it, PM me. I use it on nearly all acquired vinyl followed by L'art du Son and a RO water chaser on my Loricraft. But I'd like to hear another opinion and maybe turn some of my good buddies at AC onto it!

This kind of product would be perfect for cleaning some of the used records I have picked up. Sometimes there is stuff on the grooves I just don't know what it is. Beer, food, other unmentionable stuff could all be on there. I'd also like to see what it does to fingerprints.

I think it will work best with a vacuum machine. It might gunk up a D4 record brush or manual cleaner (is that what you use to touch things up?).

Hey Doc,

I used Sporicidin (http://www.professionalequipment.com/sporicidin-disinfectant-solution-1-gal-re-1284c/respirator-accessories/) for mildewed records.  It worked.  Is this the same stuff as Endozime?

I think I would use it in the laundry sink when I wash the record for the first time.

Hey woodsyi-
Check out the MSDS data sheets for the Endozime and Sporicidin. Apparently, the active ingredient in Endozyme is 2-propanol, and the one in Sporicidin is completely different, being Phenol/Sodium Phenate.

From orthobiz description of Endozime it sounds like it'd be completely safe on LPs, but I don't know where you'd buy it. Looks like it's for wholesale only. Anyone have any idea how safe the Phenol/Sodium Phenate in the Sporicidin would be? That stuff sounds like a good deal at $28 a gallon.  :)

Endozime has 2-propanol in it but I think it's a solubility carrier or something. I would think the active ingredients are protease and amylase but maybe those are fancy names for alcohol!!!

Sure looks like a fancy name for an alcohol bonded to water mix., i do like my alcohol bonded to wate,r mostly old scotch with rocks but i don't usually clean my records with it :lol: that being said i still wouldn't mind giving it a go

I will go back and check my records that I cleaned with Sporicidin and see if there is any long term damage.  It's been few months.  I got a haul of records that were water damaged and mildewed.  There were some that I wanted to salvage and I used Sporicidin.  It worked fine and I put the cleaned records in MoFi sleeves.  There were a couple of Sheffield Lab dirict to disc records that I wanted to save.  I will report back.

It's interesting that Sporidcidin lists phenol/sodium phenate (well known germicide) as active ingredient when Endozime only lists 10% isopropyl alcohol.  Clearly Endozime has enzymes but they don't list them. I wonder why.

The MSDS that I keep popping up on the Endozime webpage lists 2-Propanol as being 10% and doesn't say anything about isopropyl alcohol. Is that the same thing?  :)

I think the MSDS is for hazardous and toxic aspects of a product. I do not think it is meant to list the "active ingredients," hence, no mention of enzymes on the Endozime product.

I got my sample yesterday in the mail. I'm going to mix it in a 1:32 mix (making a quart) and I have 2 new used records to try it on. The stuff sure looks like urine.  :lol:

It's not April 1st is it?

I do not recommend anyone put this stuff in a spray bottle to spray records. I think it may not be good if you inhale the spray. If you do, wear a mask (not Halloween), before you do. I also think rubber gloves may be in order. I'm going to put it on with a paint brush in the laundry sink and let it soak for a couple of minutes on each side, then do a good rinse.

Post by: orthobiz on 12 Sep 2009, 04:17 pm
Glad the stuff is arriving. I think 1:32 is a good ratio but I don't think it's toxic where you need rubber gloves and a mask.

I use a refillable spray bottle for my mixture. I run the RCM machine to spread it (my Loricraft) and I spray directly into the record/brush junction. I hold the spray bottle about 3" away from the record surface. I use a 3" foam paint brush.
If you are cleaning a few records, less is required to wet the surface after the first record. There is no surfactant so it can bead up. I turn the machine off and then manually spread it with the foam brush lightly applied and swept around the surface (just the weight of the brush). You can eliminate all "bubbles" (uncovered areas) with this method. I leave if in place for a minute or two, I have not let it "dry" in place (most likely a bad idea!). I believe there is very little aerosolized and I do not detect much of an odor.

My hands with this method remain completely dry and I have experienced no irritation. In our hospital, they occasionally use this stuff full strength on nasty areas on the floor, sometimes no wearing a mask after a surgical case is complete (certainly not on my cases, I'm neat as a pin!).

And yes, it is YELLOW but it is Endozime and not any other weird hospital scientific experiment!!!

Let me know how it works. Wayner, i'm sure I can scare up a HazMat suit if you really need it! :lol:

Post by: Wayner on 12 Sep 2009, 04:42 pm
OK, I'm going to make up a quart of this stuff (need catchy name other then Endozine), then I will put some of it in my small spray bottle. If you've done it without any irritation, then I good with the spray technique too. That is actually the way I'd prefer to do it. I also agree that letting this stuff dry on the record could be bad, maybe just to get off later.

How about Vinylzine, LPzine, 331/3ozine, Cleanmyrecorddammit, Othobiz's jizz, .................... aa

I gave my daughter a copy of Strange Days by the Doors. We spun it briefly and were dismayed about how noisy it was. It had the scratchy sound every revolution that usually means it's a crappy copy. However, the opening in the sleeve was aligned with the outer jacket, so maybe it was just dusty. No visible mold despite having a faint odor (that typical basement vinyl smell).

Endozime followed by L'art du Son followed by reverse osmosis water rinse on the Loricraft and voila! A clean, perfectly listenable record with excellent dynamics. (I have the boxed set brand new and don't listen to them much so I'm NOT gonna be jealous, right???).

I did and used it on two used albums I got last week. It took off fingerprints and smudges, but in the case of the two new used LPs, they were in not the best shape, so I couldn't comment on the sonics. I'm waiting to find another dirty LP to try it again. It does seem to work, tho. Good job.

Post by: analognut on 17 Sep 2009, 08:48 pm
Have only tried it on one LP. So far, I'm with wayner in that it does seem to work, but I'm not sure if the LP was made quieter by the Endozime or the hand-scrubbing as opposed to being previously cleaned with the Nitty Gritty. Going to try it on a few LPs I've already hand-scrubbed and are still dirty-sounding. Outa time already today! Will have more to say tomorrow.  :)

Post by: analognut on 19 Sep 2009, 04:00 am
Hey orthobiz-

Thanks for your generosity in providing the Endozime.

The short story:

Endozime might or might not help your LPs.

The long story:

I ended up mixing mine at the rate of 1/2 oz. to a quart, which, although only half the strength that others used is still double the product's mixing instructions. At that strength the solution:

did as good a job of cleaning dirt, grime, and fingerprints off of my kitchen cupboards as full strength concentrated "Simple Green" does;

dried without leaving a trace when sprayed on a clean mirror;

easily cleaned grease off of the mirror when applied by rubbing my fingers across my greasy fore-head and then wiping them on the mirror;

did a super job of cleaning off the ring in the bathtub.

I spent the whole day cleaning and playing LPs (8 albums).

Four of the eight LPs were "pre-owned" albums recorded between 1967 and 1970, and purchased recently on ebay. They are well-worn and beat up. I had previously cleaned them with my Nitty Gritty, and then hand-scrubbed them using the same cleaning fluid because they were still noisy as hell. I use distilled water mixed 1:1 with the commonly available 70% isopropyl alcohol and 2-3 drops of Dawn per quart. Surprising me, hand scrubbing these four had yielded no improvement over the RCM cleaning. And I use a good brush (old LAST applicators).

So these previously unsuccesfully cleaned old ebay LPs were cleaned with Endozime today in the following manner before playing:

Place on a flat piece of acrylic into the kitchen sink and thoroughly scrub (moderate to firm pressure, two minutes per side) using old LAST Record Preservative applicators. I don't worry about getting the labels wet. It doesn't hurt them as long as you don't over-do it. They dry quickly.  Thoroughly rinse by spraying warm water from the sink's sprayer directly on the vinyl at any angle I choose. Then they are rushed to the Nitty Gritty to be vacuumed dry. Hey, I'm not gonna BUY distilled rinse water! Ridiculous.   :idea: If I can spray tap water onto a mirror and vacuum it off leaving no traces I figure I can do the same with my vinyl. When these ebay albums were played today there was a BIG change. Big reduction in number of pops, huge drop in the noise floor. Very nice. 100% better.

The remaining four were from the collection I've had for about 30 years and all were purchased new by me and extremely well-cared for. They were cleaned today in the same way as the other four. I detected no drop in number of pops and no reduction in the noise floor. Apparently I've kept them clean enough they're as good as they can get.

The last album played today was also the first album played. I first played it without applying Endozime. Playing it at the end of the day I first cleaned it with Endozime. It was recorded through my reference Juli@ soundcard into the computer both times at 24/88.2, and both files were opened in my audio editor. Confirming what my ears were telling me, there was no visual indication that the EZ cleaning had reduced the noise floor or changed the number of pops.

The moral of the story:
If you have a lot of "pre-owned" LPs which have an unknown history, then Endozime can be very effective in improving the sound. If your collection is largely purchased new by yourself and you've religiously tried your best to keep them clean (this includes using an RCM on them once or twice in the last 10 years) then there's a good chance they already sound fine!   :)

Just remember that not all noise is caused by dirt or grime in the grooves. Some of it is damage in one form or another, Some is static discharge amd so on.

Wow! What a write-up, guess you really ARE an analognut and a fellow experimenter! I have been garage saleing (?) a lot this summer and some surprisingly dusty and grimy records clean up fairly well with the Endozime and become playable. But I don't really ever use it as the only treatment, I always go with the three step process of EZ, l'art du Son, RO water. Some records get tossed despite this and any treatment will not eliminate gouged out grooves and years of abuse.

I haven't added scrubbing to the regimen and I have some old LAST scrubbers, too, as well as some plush "disposable" record cleaning hand held devices. It's just so easy to spray, suck and play!

Bottom line: I think it's safe for the vinyl, it has not rendered any disks unplayable. And it's free, my hospital has no problem giving me some (they're splashing this stuff all over at work!). Way cheaper than Vinylzime...

People at stevehoffman.tv have brought up ultrapure Reagent Water as a mixing agent. Lord help me, I called over to the hospital lab and yes, they carry this stuff!

The sickness continues. Contact me if you want more enzyme!

Post by: analognut on 19 Sep 2009, 03:51 pm
That's cool. Thanx again Ortho. The free 1 oz sample should last quite a while. I used an 8 oz sprayer and it's still 2/3 full, which works out to almost exactly using 1 oz  of solution per disc, and that equates to having enough EZ left for 120 more LPs! As effective as it was on the grungy ebay albums I'll stick to that percentage, which, in case anybody's interested was 1/2 oz Endozime per quart of solution.

And yes, I, like so many others just got to the point where I no longer purchase CDs because they don't give me satisfaction! So I have unintentionally become an analognut. Experimenter? Sure! That's parta the fun!
