Q&A for How to Make Homemade Liquid Dish Soap

You can add some food coloring, but that may stain your hands and/or dishes. You can also try getting some soap-making dye either from an arts and crafts store, or from an online soap-making supply shop.

Dove soap works well.

Many people boil vinegar, let it sit/scrub it and then put water on it. Scrub roughly, but don't scratch the surface.

Yes, but I would not recommend this unless there is some reason you need it to be colored.

Yes, it is safe to dry and crush it, then after you'll mix it together. No, the smell would not be that effective. And also, to make a fresh mint detergent without adding any soap, you can just smash it then grind it.

Essential oils add fragrance to soaps, cleansers etc. If you want your liquid dish soap to smell good, you need to add essential oils. If you add other oils, for example olive oil or walnut oil, your liquid dish soap will neither clean your dishes nor smell good.

Coconut oil soap is a good substitute you can use instead. It is safe to use for cleaning vegetables, washing or shaving your body and face and keeping your pets clean without drying out their skin.
