Tips for saving money on dish soap.
Fill a pump bottle halfway with dish soap and the rest of the way with water. It uses less soap, but still produces great suds.
We also dilute our dish soap, but one of the things we also do is buy the same soap for everything. Plain castille liquid soap can be used for dishes, hands, showers, laundry, cleaning surfaces, even as shampoo (but it's not my favorite for that). You can shampoo the dog and wash floors with it. Liquid castille soap is not terribly inexpensive but if you use it for everything, you avoid paying a variety of prices for a variety of items and time spent having to shop around for all the best deals on 10 different cleaners. And then you can also by it by the case and get a better deal. (Usually 4 gallon jugs.)

Here is a way to control how much soap comes out of your dish soap container. Get a sturdy spray nozzle from an old bottle and just screw it on.
I keep a dish detergent dispenser on the sink. When I refill it, I fill it with about 1/3 water and the rest with soap. I shake a little to mix. I find it works just as well as full strength detergent.
This started out as a treat for myself but has really turned into a money saver. The kitchen sink area became more "elegant" once I purchased a bottle with spout designed for use with cooking oil.
I had a nice pretty hand soap pump container that I had gotten from my niece. When it was empty, I filled it with dish washing liquid soap and I leave that on top of the sink to be used for either hands or dishes.
I have a tip to help save on dish washing liquid and to look pretty at the same time. I went to the Dollar store and bought a decorative oil dispenser.
Do you remember when the ultra dish soaps came out? At that time the manufacturers said to dilute the soap, using, I believe, 2 parts soap and one part water. I have a bottle on my counter that I add dish soap to with the water in those amounts.
I add a few drops of essential oil to Free and Clear (hypoallergenic) dish soap to mimic the expensive all-natural soaps without the possible allergens, since even all-natural soaps can have natural ingredients I'm allergic to.
To stretch your dish detergent, use "bubbles" refills from the dollar store, the type kids use to create bubbles. The cost is about $1 for 32 ounces.
For making your dishwashing soap last longer: Take a separate plastic bottle with a pump and fill about one third of dishwashing liquid of your choice.
