50ml of 99% isopropyl alcohol
5ml of Triton
1ml (a few drops) of PhotoFlo
Fill the rest with distilled water (about 440-445ml)
The Triton and PhotoFlo are not necessarily easy to find, but in his memory, this is what I use, and now I have enough to last awhile. It does create a few suds...not sure from which chemical. After washing, and then rinsing the tub thoroughly, I do a second treatment/rinse on the records with just distilled water.
Of course, the dishwasher rinse aid is much easier to find than Triton and PhotoFlo, and I'm sure works very well. But when I saw the subject title of Knosti, I thought of Bob and had to post this :| He had purchased on Okki Nokki to replace his Knosti.
The propylene glycol is sticky and not recommended for records (If you use a photographic product alone, then Ilford's Ilfotol is better as it doesn't contain the glycol, just the surfactant). Hence, there is no reason to add Triton X-100 (= octylphenoxypolyethoxyethanol), then more triton with photoflo. The surfactant is the same and the glycol is bad.
Dishwasher rinse aid is acidic as heck, it also doesn't belong on your records. Preservationists agree: You will never find the best record cleaning agents in your supermarket.
I agree with you, and am glad you pointed this out. You may recall this post from about a year ago https://www.vinylengine.com/turntable_f ... lit=triton where I offered a new concoction which (I believe) had your blessing.
It contains the following:
*Triton X-100 (standard grade)
*Hepastat256 (this is a 'Quat', and their concentration is what works for my proportions)
*99% Isopropyl alcohol
Here are the proportions for 500ml of cleaning solution:
- 25ml of isopropyl alcohol; measure in smaller measuring cup, and then pour into larger measuring cup.
- 0.75ml of Triton using a pipette; it dissolves quicker in alcohol than in water, so add it here into the same large measuring cup; stir it around a bit. Rinse the pipette inside and out - suck water into it and squeeze out several times.
- 0.25ml of Hepastat256. Rinse the pipette again and then set it aside for the next time you need to make a batch.
- Fill the rest of the measuring cup to 500ml with distilled water, and stir.
I hope you still concur :D
