Acid washing removes the old and dirty top layer of plaster, concrete or other types of surfaces and reveals fresh and clean layer of the surface from underneath. It is an ideal way of removing those stubborn stains and spots that never go away with normal washing. Acid washing is also used for cleaning long ignored pools from unwanted algae, minerals that get deposited overtime and stains.

The process of acid washing involves applying the right quantity of the hydrochloride acid to the concrete and wait for some time to let the acid soak into the surface. Then the treated surface is rinsed with water by setting the pressure washer at about 3000PSI to wash off the acid. Baking soda is sprinkled on the washed surface to completely neutralize the hydrochloride acid.

Every care should be taken by the person before handling the hydrochloric acid as it can cause skin burns and it may release toxic fumes. It is important to wear proper clothing and use the right gear such as protective goggles, gloves and shoes made of latex or rubber and breathing equipment in order to protect oneself from the harmful effects of the acid. One should also correctly follow the instructions prescribed on the product by the manufacturer for safe and effective cleaning.
