Use Detergent!

Post by oxford »

I wouldnt recommend the no detergent method. Dirt can removed through mechanical action that way, but detergents are meant to reduce the surface tension thereby allowing the soils to wash away or release more easily from the surface being cleaned. Not using a detergent will result in a greater redeposition of soils - in other words just moving the dirt around and not washing it away!
