The Total Wash Cannon has a dilution dial on the top of it that controls the ratio of Water to Total Wash Solution. Turning this dial clockwise will increase the concentration of Total Wash Solution. For muddy vehicles we recommend setting the cannon to full foam (Turning clockwise all the way). For dust, road grime, or fine detailing we recommend dialling it back which will decrease the concentration of Total Wash but still clean effectively and give you a nice finish.
Total Wash is a highly concentrated all purpose cleaner that has been designed to work great on heavy soils such as mud and clay. That being said it can be used to clean most surfaces. Common uses of Total wash are off and on-road vehicles , farm equipment, vinyl and aluminum siding, trailers, and pretty much anything else that gets dirty!
In truth it depends on the application. In almost all cases Total Wash serves as a highly effective touchless wash. However long standing grime may require slight agitation to get a perfect clean. (example: Siding that hasn't been washed for extended periods of time or bugs that have been baked onto the surface and left for a long time)
Total Wash is a highly concentrated formula that is meant to be used at a 20:1 (20 parts water: 1 Part Total Wash) ratio or higher. It is perfectly safe and very gentle on all vehicle components when diluted to this ratio or when used through the Total Wash Cannon. We do not recommend using Total Wash straight or letting Total Wash dry on your vehicle as the water will evaporate and leave a very high concentrate on the surface. For best results rinse Total Wash off after approximately 60 seconds.
