Cleaning oil from concrete with muriatic acid.

Before washing your driveway with muriatic acid try a degreaser on oil stains and a solution of one part bleach to three parts water on mold and mildew. It cleans concrete by removing the topmost layer of your driveway. The acid works well on concrete and on many masonry projects because it neutralizes alkalinity. Muriatic acid is diluted hydrochloric acid and is a very potent chemical.

Scrub the gray stain with a solution of 1 cup liquid chlorine bleach 1 cup powdered laundry detergent and 1 gallon of very hot water. While some stains can be rinsed away with a pressure washer tougher stains such as rust require an acid based cleaner like muriatic acid. Mold rust and other stains can mar the clean beauty of your concrete lessening the visual impact and even the curb appeal of your property. Mixing ammonia with bleach creates a lethal gas similar to mustard gas.
