I mix my own in those distilled water haze plastic jugs, it's much easier to pour from those.

Here are links for all the ingredients (non-affiliate):
Ethanol: laballey.com/products/foo... or
Denatured ethanol, non food grade (don't drink it): a.co/d/1zC4YIv;
Citric acid: a.co/d/5lILV0i;
Dish soap: a.co/d/cqJTleO;
Distilled water: a.co/d/jkZPVeZ.

Or you can just try using simple table (distilled) vinegar mixed with citric acid and lemon essential oils in place of rinse aid after all, as any other recipe in the internet suggests. It seems to work as well.

And if you use isopropyl alcohol or denatured ethanol (which is basically ethanol mixed with isopropanol and/or methanol so people don't drink it) it should be, like, two times cheaper.

Considering price of ethanol as about $140 (including hazmat delivery fee and taxes) per gallon, the rinse aid we made, with that ethanol as most expensive ingredient in the recipe, comes out slightly pricier than the store bought one, but, hey, at least you know what's in it.

Citric acid here is to dissolve salts and minerals so they are easier to be washed off with droplets running down or are better distributed inside the droplets which are left on the dishes to dry out on larger surface we talked about earlier.

Ethyl alcohol in the recipe helps to eliminate foam mostly expected to be produced by the dish soap. And, as mentioned, food grade one is recommended exclusively based on the intention to make it as not harmful as possible. However, it is quite pricy to get, thus the substitutes are mentioned.

However, considering that it's made with idea in mind that people do not rinse their dishes very well when cleaning them with their hands – it should be good enough. Have you seen that tiktok where British people do not rinse soap of their dishes at all? t.co/LirOXPAsr0

And in our case that is exactly what dish soap does in the mix, and that is why we need it so tiny amount, consider measuring those 0.1 ml with a syringe or you can add just two drops of it. One concern here is that dish soap can leave some residue on its own.

...easily so they don't leave mineral residue after drying out, or get a bigger area to dry off of to distribute dissolved in it salts and minerals on the larger surface to, basically, make them less visible. To do that rinse aids tend to lower so called surface tension of the water droplets.

First let's cover dish soap, since it seems to be most out of place in solution which is supposed to rinse something like itself from dish you wash in your dishwasher. Basically, main purpose of a dishwasher rinse aid is to help water droplets accumulated on dishes to get off the dishes...

Everybody has heard about that scientific research, pubmed.ncbi.nlm.nih.gov/36464527/ regarding commercial dishwasher rinse aid that destroys, to some extent, your gut lining by utilizing alcohol ethoxylates in their contents. Here goes a little explanation of the purpose of the ingredients.

Ethanol can be replaced with non food grade 95% denatured ethanol or even with 96–99% isopropyl alcohol — but we are on the path of healthy alternative to store bought solution here, aren't we?
