Water and Johnson & Johnson Baby shampoo mix. fill the bottle with water and a few drops on shampoo and mix. just enough so you can feel the shampoo in the water.
I doubt youll have to use this what you have above looks like it will be enough.
Good Luck your a Brave man for attempting this yourself.
