For the Love of Hot Water

We have been living in our home without hot water for 3 1/2 days. Last night at at about 10:45 we finally had some. We weren't without it that long after Hurricane Ike. Anyways, I'm happy to have it back. Lucky for us we could take showers at the health club, but I'm not real fond of public showers, they are individual showers, but still public. Yesterday morning when I went to take my shower they were cleaning them and at that point I realized I have been cleaning mine wrong. They had heated, soapy, power washers spraying them down. Why didn't I think of doing that, a lot less scrubbing. Now I am wondering if I can hook our power washer up some place in the house to clean my showers.
