In some instances, gas and diesel stains may need to be removed using Foamer and Flat Surface Cleaner . If you decide to use a foamer, you will connect your wand to the Foamer twist fast adapter. The Foamer will create foam using cleaning detergent or soap. When applied to the surface it will stick to it for a longer period of time allowing the detergent to emulsify the stains systematically and thoroughly. After that, you would disconnect the Foamer and connect the Flat Surface Cleaner . This machine has a flat round cleaning surface, two hand handle and three wheels for easy maneuverability. Use this cleaner to remove the "shadows" still visible on the surface. Clean the tough spots by going over them several times if necessary. Surface cleaner will most of the time clean the area better and faster. Clean gas stations are much safer than those covered in oil!
Sometimes leaf stains seem to be the problem. At times they leave ''ghost" stains that want to linger after the job has been finished. Here is the solution: Mix a gallon of liquid chlorine with 2 gallons of water, and spray it directly on the stains ( DO NOT put any bleach or chlorine in your machine; they will damage the parts and components). The stains are gone in 5-10 minutes. Then rinse the area one last time. In extreme cases you can use citric acid, but be careful with the amounts because acids tend to brighten the concrete, so an even application is critical. Chlorine can also be used for tire marks. Make certain you are power washing the area thoroughly every time you use chlorine. Advise! Make sure you check the local jurisdiction regarding fuel and oil removals. Some states require all spills to be removed by taking them off the premises and being cleaned instead of washing them off into the drainage system.
