The soap free from MB ate brass, liquid slurry and effiecent extract left a lot of white powder build up regardless of uncle Larry's rinse theory. Effiecent extract says right on the label flush, I think because of a anti resoil agent. Also magic potion left a wicked white powder coat, but in defense of magic potion the outbound check valve valve lost an o ring on the machine a chemical was flow through out the whole machine. Formula 90 powder completely disappears like your using nothing when your using high heat.
