The Soft Washing Method in short is the systemic cleaning of bacteria. This method of cleaning is used by many in the power washing industry. Soft Washing kills the bacteria on contact and works by attacking the organisms microscopic roots holding firmly to your roof or other substrates. Bacteria such as algae, mold and mildew that grow on surfaces are eliminated by the soft wash cleaning method. By using this method of cleaning you are applying a biodegradable cleaning solution to remove insect droppings, nests, dirt and grime from the environment. Unlike the pressurized power used to cleanse porus concrete or brick, soft washing uses low pressure and algaecide chemicals to react with the organic growth, leaving you with a bright and sterilized area.
This method of cleaning is best for roofs and exterior house wash cleaning but it can also be applied to various other dirty surfaces such as brick, concrete, wood, stucco, windows and vinyl sidings to name a few. It is not recommended to use high pressure when cleaning barrel tile roofs or asphalt shingle roofs because the force applied in cleaning will lower life expectancy through scaring and potential damage of fragile particles. Soft Washing reaches deep into the roofs porous material with low pressure and reacts with the organic roots. The cleaning solution used roof cleaning are water based and do not cause harm to the surrounding landscape vegetation when used by a knowledgeable professional. After about a week the cleaning solution breaks down and dissipates.
This form of cleaning roofs is superior because it can last four times longer than dangerous high pressure cleaning. High pressure roof cleaning only removes the bacteria from the naked eye, the tiny bacterial spores are still embedded deep within the pores and grow back within months. Therefore cleaning roofs with the soft washing method is more cost effective, environmentally sustainable and a damage free solution.
In conclusion the soft washing method is the best way to clean organic growth on various surfaces through non hazardous chemical applications targeted at eliminating organic bacteria eating your roofs fragile stone.
