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.
