It depends on what kind of fragrant compound they use but some can also be beneficial to cleaning (e.g. some terpenes). The quat preps also often contain dyes. Unfortunately, the nature of these included compounds is proprietary information. The good thing is that they are typically present in very small amounts and we are diluting 1000-fold or more. If you are looking for a commercial product, it's something you have to put up with, much like the people who use dish soaps or shampoo/conditioners. There are many suggestions for pure quats in this thread but they are difficult to find and work with. The best compromise is to find a commercial prep that minimizes dyes and perfumes.Several of those listed, have fragrance added. Any negative effects from those compounds?
I found the MSDS for Virex II 256 and diluted at 256:1 the pH is 8.8. Correct me if I'm wrong, but at the dilution levels we are using these quat based products in record cleaning solutions the ultimate pH is not an issue. I suspect it is very close to neutral 7. Also, most of the Hepastat 256 replacements listed above have some kind of fragrance in them. Are there any problems created by the fragrance?
Thanks for the reply. Dang, I can't even hardly remember my name before I've had my coffee!A little early for me to be doing math (pre-coffee), but It looks like your stock is 0.4% Triton, 0.03%Quat (assuming you are starting with a 10% commercial concentrate...you don't mention) and 2.3% IPA. And your 1 gal. working solution is about 0.02% Triton, 0.002% Quat and 4% IPA. This should work well for US cleaning. You could increase the IPA to half a cup to make it easier than measuring out 6.5 tablespoons (resulting in around 5%).
Yes, that is Ruston's recipe. I use similar for hand cleaning but found I can get by with less reagent in my ultrasonic bath and this makes rinsing easier. Your mix is a little low but it should work. That said, for optimal results I would start with adding 8x more of the surfactant stocks so you end up with 0.16% Triton and 0.016% quat and give it a try. The quat can be increased further if you are finding issues with static or the records are moldy. That way you are above the CMC of Triton and have enough quat to be effective. You won't get excessive foaming with this mix, it just is about how you rinse and dry. Some just spray and drip dry, others wipe, others put on an RCM. Since there are so many variables, I prefer ranges and hesitate to recommend exact concentrations. Complicating the issue is that commercial manufacturers provide wide concentrations ranges (sometimes 10-fold!) in their products for propriety so it is impossible to know exactly how much quat we have. It's best to experiment: wash, look, and listen. You want to use the minimal amount that cleans and rinses well, leaves no residue, and yields a record free of non-structural noise.Thanks for the reply.

Isn't the Triton100 recommended to be around .13% on the final solution? And the 10% Quat to be around .10%?
Hoping this thread isn't dead! I recently got a US rig up and running and I'm getting great results, but I feel like the fumes from the cleaning solution are giving me headaches/making me feel woozy. I'm using Rushton's formula -
0.13% Tergitol S-15-3 and S-15-9 in a 50/50 proportion
0.10% Hepastat 256 (a 1:1000 dilution)
5.00% isopropyl alcohol (using 91% grade)
The room where I do my cleaning is small and not well ventilated - when I have the cleaner running and the lid off there's a pretty strong chemical smell in there. That said, I haven't thus far been doing marathon sessions - half-hour at a time in there at most. I've also wondered if my Chinese US machine (the Trusonik sold on eBay) is offgassing because the smell is far and away the strongest when the machine is running. So... just wondering if anyone can't give me any advice on this. I'm starting to feel a little paranoid because in general I feel like I haven't investigated the safety of these substances and I'm worried that I've been a little too cavalier.
I noticed this as well. Peering in for a closer look it coated my eyeglasses in a thin fog. After that I started wearing a particle mask.Hoping this thread isn't dead!

I did read someone in one of these DIY threads posting that the Library of Congress recommends wearing safety goggles, gloves and respirator when working with 100% tergitols. Which gave me pause...
