The DIY mix is a great surface cleaner, but it's missing the alkalinity and glycol ethers that make the real thing work on baked-on grease. If you want the DIY version to actually match the commercial performance, you have to bridge that pH gap—otherwise, you're just spraying diluted soap.

The Chemistry of the "Home Upgrade"
​The DIY recipe in this post (soap + alcohol + water) creates a functional surfactant spray, but it lacks the alkalinity required to match the original product's speed. Regular dish soap is formulated to be pH-neutral for skin safety, which limits its ability to chemically break down polymerized (baked-on) grease.
​The Mechanical Upgrade: Adding Washing Soda (Sodium Carbonate)
Adding approximately 1/2 teaspoon of Washing Soda to a 16 oz spray bottle fundamentally changes how the solution interacts with lipids (fats):
​Saponification: High alkalinity (pH \approx 11) triggers a process called alkaline hydrolysis. It essentially turns the grease on the pan into a water-soluble soap on a molecular level before you even start scrubbing.
​Surface Tension: The alcohol acts as a solvent to lower the surface tension of the water, allowing the alkaline "attack" to penetrate through thick grease layers more rapidly.
​The "Salting Out" Risk: To prevent the soap and powder from separating or clogging the nozzle, the washing soda must be fully dissolved in warm water before adding the alcohol and soap.
​Important Constraints
​Avoid Aluminum: This high-alkaline mixture will chemically react with aluminum, causing permanent oxidation (darkening/pitting). It is for ceramic, glass, and stainless steel only.
​Skin Barrier: Because the pH is significantly higher than standard soap, it will strip natural oils from your skin faster. Use gloves for heavy cleaning.

please do know that while I theorize that adding the washing soda to the mix will increase the cleaning power, I have not tested. would love for somebody else to test it and tell me if it's viable as far as not clogging and generally helping.

Some dish soap. A little rubbing alcohol. The rest water. Scent as needed. If possible don't pay a corporation for something you can make at home.
