Just checked the Eucalan website and they are celebrating their 25th Anniversary! Great product that's been available some time.
I must agree with the "intelligent" washing machines. I cannot get the machine to cover two king size sheets (for that matter any load) in a high capacity machine with sufficient water to wet the sheets! The machine weighs the contents and adds water, so I faked out the machine by wetting my loads with water (I, too, had to attach a garden hose to the utility sink to wet the laundry but not add so much water that the machine empties it....lesson learned too.) and then I can get barely enough water to adequately clean the sheets. If I had a way to get home my basic Sears model (many years old) from my cabin in the mountains I would definitely trade the machines. Expensive lesson learned!
Where I live, we start our water bill at $50 per month before using a single drop of water! It can get quite expensive if you aren't smart about water usage.
