Vesta Wash completed  a total exterior cleaning of this house in Newark, Delaware using a revolutionary method that uses a calcium based bleach.  Why did Grandma save the egg shells in the coffee can?  She wanted to add their calcium to her flower garden.  Vesta Wash is the only company in the greater Philadelphia area that has invested in this new technology from Softwash Systems that can safely clean roofs, stucco, siding, concrete and decks without damaging plants.  There is a small amount of white left on the roof that rinses with the next rainfall, but without damaging the roof or plants.  ***note that no plants were harmed during this cleaning***
