I bought a power washer 25 years ago to paint my house and only used it once. I recently moved to AZ where the water is high in calcium and I have to clean thick deposits of calcium from my swamp cooler. It is very time consuming scraping it all off, but then I remembered I still had the power washer. I have House Wash soap and I wonder if there is something better to use.
