Acid Wash

Stains and calcium deposits are often found in swimming pools.  In order to remove these, hydrochloric acid and water are used when mixed together.  The acid wash itself is solely for the stains as opposed to “etching” which takes down part of the plaster surface when repainting or replastering.  Generally this procedure is done when the pool is drained and scrubbed to access the debris and stains that need to be removed.
