I did an informal experiment at home using several possible wetting agents(surfactants) on a bead of water, and Jet Dry was by far the most effective. Effective for me was how fast the agent worked, how far the combined fluid spread out, and the degree of flatness. Other wetting agents tested were Isopropyl alcohol, Windex, Photo-flo, Triton X-114, and Chemtronics SD-43. To be fair, the highly concentrated Triton X-114 was not diluted enough.
Jet Dry is fairly cheap, easy to find in the cleaning products of the grocery store, and comes in small quantities. Be sure to purchase the clear Jet Dry to avoid colored dyes that may not wash away without a lot of effort.

Jet Dry.
How much did you use per gallon of cleaning fluid?

from the end of a toothpick. Right now, I cannot remember how much I used when I made up a homemade cleaning solution for my son. I will have to get back to you on that when I can contact my son, as I wrote the quantity on the container he uses.
I personally use Triton X-114, because I purchased the concentrate from a chemical supply house. This is pure surfactant plus distilled water. With Triton X-114, I use 1/8 tsp per 500ml(approximately 1/2 quart).
I determined the quantity of X-114 and Jet Dry by simply mixing these surfactants in 500ml of distilled water until I achieved the wetting(spreading) that I desired on the record surface. I always use just the minimum amount necessary.
Did you use any dish washing liquid (like Dawn) in your home brew? Or just the jet dry?

in powdered form. I use 1/8 tsp of the powder in 500ml of total solution. The closest grocery store product to this is original Woolite. Woolite is excellent because it only contains surfactants and no dyes or perfumes. From everything I have read, both Woolite and Labtone have one surfactant that is also in one of the Disc Doctor products.
Again, I will have to contact my son to see how much Woolite I used in his record cleaning solution.
