To the question, what do people use to wash elephants, the answer is: Murphy Oil Soap (so I've been told).

This is a plug for Suja Uber Green Organic. I tried this veggie juice and really felt my internal energy rebalanced--which is not something I very frequently experience with health drinks.. They've really figured something out. Available at Target.. 

For many cleaning products, it's not enough just to spray it on and scrub or wipe. Some solutions need what is called dwell time--time to sit on the surface in order to break up the soil that's there. This is especially true for more heavy duty products and when there is heavier dirt to get at. In a shower, for instance, you can spray a good bathroom cleaner on and give it up to 10 minutes to loosen the soap scum. It's a good idea, right after you spray, to wipe the solution evenly over the surface with a scrub brush (not scrubbing it though). Dwell time can make a lot of difference.
