What's your Housewash?
I don't think this has been covered here. What are you using now and what were you using? How is it better?
I use Emulsifier Plus. Simple Cherry in some situations. Mix with Sodium Hypochlorite when there is mildew. I downstream the majority of time. I used to use Mighty Max(Butyl, Metasilicate). I tried citracleen but was'nt impressed. I have'nt used anything that lifts pollutants like E-plus, especially spider eggs.
