How can I easily release one drop of liquid dish soap at a time?

Congrats. You found a person just as cheap as you are.

I have a little pump soap dispenser that does exactly this. I made you a video of it.

@johnpowell hahahaha that’s sufficient, so basically a hand soap pump.

Correct. I got mine at a garage sale.

And I was kidding about being cheap. Well, I am still cheap but the soap thing is more of a environmental concern.

And normally when I do dishes I do them right after eating. And I only have two plates and two glasses and pretty much two of everything. So a drop of soap on the sponge and I can generally get through the dishes for a meal. I rarely cook meat or use oil or butter so most of my my dishes just take a a drop and a quick scrub and a rinse.

Saw the video. I’d have used the soap stuck on the side of the container. That’s good for two washings right there!

You guys are my heroes!

I’ve got some data for you. I just ran an experiment to determine drop size. With that information you can dilute the soap with water and use a conventional pump that delivers a much larger amount.
I used Wegmans Ultra Dishwashing Liquid (blue) and used a lab squeeze container to deliver 10 drops onto a Mettler lab scale 10 drops weighed 0.21 gm. Figure one drop as 0.021 gm.
One full pump from the dispenser of Wegmans Lychee Berry Moisturizing Hand Soap weighs 1.8 gm.
You can dilute the dishwater soap, (1.8 grams per squirt / 0.021 grams per drop) = 85 water to one part soap to get one drop of soap per full squirt of liquid. So, put 3 ml of soap in the 240 ml bottle and you are good to go.
If you have a different dispenser, say one that only delivers 1 gram or 0.5 grams per squirt just adjust your dilution ratio accordingly.
Keep a second bottle of undiluted soap nearby for refilling, tough jobs, and (most important!) for company, so they don’t wonder or worry about your potentially penurious behavior.

Get a squirt gun. or small plastic bottle that you can put a dispenser lid on or that has a eye dropper type/like lid.

The amount that gets stuck in the cap is enough, in itself, to soak a pot or something. Take the cap off and throw it into the pot of hot water. Another advantage is it will clean the cap of gunked up soap.

I was going to suggest a tiny nail hole for your dilemma. With the cap closed, take a thin nail (like a tack nail) and hit it through the top of the cap with a hammer. It may come out as more than a drop but it won’t be as much as the regular cap hole will release.

Also, do what @LuckyGuy says – dilute with some water as soon as you have space in the bottle.

I use dish soap for hand soap when I’m at work. It’s way cheaper than liquid hand soap. Maybe a dollar for 16–24 oz. vs. 3 dollars minimum for 12 oz of fancy hand soap, unless you do the pump bottle of Softsoap, which will be about a dollar for 12 oz.

@Ltryptophan I share your frustration. I went to a beauty supply place and got one of those bottles which have a sort of long skinny dispenser nozzle top. (beauticians use them to apply color and probably all sorts of products) Put my dish soap in that and can now get one drop at a time if that’s what I want!

Just, very gently, squeeze one or two drops. Okay, my soap complaint is that even a few drops of Dawn dish soap ( my preferred brand ) gets my dish scrubby sponge too soapy, sooo, I just dribble a few drops into a cup or bowl, fill with water then disperse the soapy water to the other dishes. haha I hate having to rinse and rinse and squeeze and squeeze the sponge out so I can then wipe the counters.
