Record Cleaning: Developing the Best Possible Methods

Michael Fremer is still cool !!!I
I was looking researching dedicated electrical lines and grounding, took a tour through his basement and then found

yea, it's utube, but still....

@Fishead thanks for sharing your method and the welcome! I wasn't able to find a source for the Hepastat 256 offering less than a case at significant cost, so I purchased some of the individual quats mentioned in the thread.

Maybe I'm completely overthinking this? To get the behentrimonium chloride percentage in the solution maybe I just apply the percentage from the pellets?

So to mix up a 20% (w/v) behentrimonium chloride stock solution:

(50g pellets / 200ml water) x 100 = 25% pellets

80% of the pellets by weight is behentrimonium chloride, so 80% of 25% is 20%.

So I'd end up with a 20% behentrimonium chloride and 5% ethyl alcohol solution?

It's been mentioned multiple times the percentages don't need to be exact, but I do want to be able to consistently reproduce the solutions.

Ok...this is my first post here so we will see how it goes. I used this site quite a bit in the development of my vinyl cleaning station so figured I would share my "findings" in respect to this question in case it may help someone else (or I am shown the error of my ways!).

From what I read in the MSDS for Hepastat 256 (from Staples), the total percent by mass of the quats in Hep 256 is 21.7%. Given Hep 256’s specific gravity of 1.008 I converted the .01% targeted volume of Hepastat into a (hopefully) very close approximation to the mass of quats to include in my solution. I was then able to weigh out and dissolve the behentrimonium chloride from Making Cosmetics and add it to my mix. In short,

[(Desired volume of Hepastat256)mL x 1.008 (g/mL) (Specific Grav/Density) x .217 (percent by weight of quats in Hep256) ] / .8 (percent by weight of the quat in pellets)]

You should fit right in around here, especially this thread.

Whew! I participated earlier in this thread but I misplaced some of my notes so I went on a search for both RCM and Ultrasonic recipes generally accepted by the OP Vince and found:

RCM (VPI, CanFab):
1:500 Dilution of Hepastat 256 (I use Virex II 256)
0.2% Triton X-100
5% IPA

Ultrasonic Bath:
1:1000 Hepastate 256
0.13% Triton X-100
5% IPA

The Triton % can increase or decrease depending upon how dirty the records are as long as they are rinsed with distilled water (2X in my case) so I'm currently using with my CanFab RCM:
0.1% Virex II 256
0.15% Triton X-100
5% IPA

I know there are a lot of folks who adjust these recipes based upon their experience and needs but I believe the recipes above generally reflect what Vince concluded. Are these what Vince, @phantomrebel, found acceptable?

I recently obtained some Maxim Germicidal Cleaner, which shares some of the same active ingredients as Hepastat256. I’m not sure if this is a good substitute, but perhaps someone else can weigh in?


I also have another seemingly less complex one called Virex Tb:

Assuming that the "Other Ingredients" are just water, I see no problem using those biocides in substitution. If you feel that they are necessary.

If it were me, however, I would want to make sure that there was nothing in the "Other Ingredient" pool that could cause problems. At the low concentration used in the final mix, however, I very much doubt that there is any cause for concern.

I just got off the phone with the Maxim company and they told me this product is intended for use without any dilution or other chemicals (whereas Hepastat256 is intended to be diluted), so this may be ineffective and/or be detrimental as we don’t know the other ingredients.

Moderation Note:

This thread is designed and intended with very carefully, and clearly specified goals. We almost lost it some time back and I worked very hard to restore what was lost. The methodologies and chemistry involved here have been very carefully developed. However, with the prime agents in this thread being missing for an extended time, it was beginning to be taken severely off its intended tracks. In order to preserve all of the hard work that has gone into what has been developed here, I have removed much derailment, and am closing this thread and making it a sticky. This is so it can be referenced as needed.

Others may have other methodologies and chemistry in their record cleaning processes, and that is just fine. Feel free to put those kinds of ideas into other existing threads, or start other threads to put such forth.
