Muriatic acid to clean oil from concrete.

The acid works well on concrete and on many masonry projects because it neutralizes alkalinity. Add small amounts of lime and muriatic acid until the leftover acid is all gone and the solution is no longer fizzing. For many years it has been the standard cleaning method to prepare concrete for coatings installations to remove stains of any type from concrete and to remove concrete slurry or efflorescence from bricks. Despite its effectiveness muriatic acid should be used on concrete stains only if you ve tried gentler alternatives to no avail.

Slowly add the muriatic acid. If you add water to acid you may cause a chemical reaction and create an explosion. Working with muriatic acid is dangerous. Also remember to add the acid slowly to the water source.

The surface becomes etched and clean which allows for the proper adhesion of a new coating. It s very important to only add the acid to the water. Make sure you wear your respirator and gloves and lean as far away from the bucket as you can to minimize any danger of being splashed. Mix the acidic solution make a solution by adding one part acid to three parts water.
