The BMI Accessories Foam Lance will allow you to spray a layer of foamy shampoo on your vehicle's exterior when attached to your pressure washer! Just pour any shampoo in the reservoir, connect to a pressure washer and start spraying foam on the exterior. The light and fluffy shampoo mix will produce a thick coating of foam that stays on the exterior and doesn't run off. The shampoo will instantly create a slick surface that starts to break down contaminants and loosen them for safe removal with your wash mitt. This means your washing process is safer and more effective! It's an incredibly durable unit made by MTM Hydro which is an industry leader. This Foam Lance features an adjustable intake, so you can increase or decrease the amount of foam created. Another great feature is the various spray patterns available to meet your needs, with a simple twist of the nozzle you can go from a 0 degree jet to 50 degree fan pattern. You can use this Foam Lance with virtually any pressure washer that is between 700 to 3000 PSI. Therefore if you own a pressure washer and want to clean your vehicle look no further then the BMI Accessories Foam Lance!
