Q.Neem oil and dish washing liquid
I am reading that to make a neem oil spray I should use Neem oil, water, and dish washing liquid. It says an “eco-friendly” dish washing liquid. How can I tell if my dw liquid is eco-friendly? I have some non-concentrated Dawn that says it contains no phosphates and has bio-degradeable surfactants. Another bottle I have is concentrated and says it contains surfactants both anionic and ionic. Would either of these be okay or should I choose another type? Are there any brands that you recommend? Thank you!
Regular Dawn that does not contain any fragrance, bleach or oxygen cleaners can be used.
