HOW TO REMOVE STAINS FROM CONCRETE SURFACES

Almost any stain can be removed from cured concrete. Treatments for the removal of the most frequently encountered specific stains are listed and include metallic and bitumen stains. To remove deep iron stains, the surface should be soaked with a solution made of one part sodium citrate crystals in six parts water. Copper or bronze stains may be removed with a paste of sal ammoniac, powered talc and ammonia water. Ten to 20 percent solution of muriatic acid will remove aluminum stains. The details are also given for the removal of motten bitumen, emulsified bitumen, cutback bitumen tire, grease, lubricating oil, and paint stains.
