Smart anons make their own products. Here's one I use.
Grease-Fighting Lavender Dish Soap
Materials
2 cups water
1/4 cup all-natural soap flakes or grated soap
1/4 cup Castile soap
2 teaspoons super washing soda
1 teaspoon vegetable glycerin
30–40 drops lavender essential oil
Instructions
Bring the water to a boil in a saucepan.
Add the soap flakes and stir to dissolve.
Add the Castile soap, washing soda, glycerin, and essential oil.
Stir well, making sure everything is dissolved.
Carefully pour into a bottle with a spout or pump.
Allow to set for about 24 hours before using.
Notes
Note: If it's too thick, add a little more water. Different factors can affect the thickness of the soap—the water you use (filtered vs. tap) and the brand of soap flakes or grated soap. If you want a thicker version, pour the soap back into the pan and warm it up again. Add a little more washing soda.
