I don't seem to load up that much with the MWF, 10-15 circles with the really hot water and it seems to be fine for me, and my puck was unused for 2 months at least. I think the hot water helps the uptake of the soap
I have a pet hate of dabbing the brush in water after I've loaded up, I just don't like it for some reason, this is why I like this method so much
