The best shampoo to use with your Master Blaster! The Metro Vac Car Shampoo Premium Car Wash Solution was created specifically with air dryers like the Metro Master Blaster in mind. Metro Vac Car Shampoo's proprietary design contains plenty of lubricants that cause prevent water from sticking to the surface, making blowing them away easy! These same lubricants also mean that there is a drastically reduced chance of washing-induced swirls. This means that using Metro Vac Car Shampoo with your Master Blaster is guaranteed to provide you with the safest wash your car has ever seen! But the safety of a wash is not the only thing that is important when you are looking for a car shampoo. Metro Vac understands this and thus developed their Metro Vac Car Shampoo to also be one of the most effective shampoos as well! Metro Vac Car Shampoo is formulated to produce as many suds as possible. The abundance of suds increases the level of clean that Metro Vac Car Shampoo provides. This is because the suds work to encapsulate the dirt and grime on your car, making it easy to rinse them away once you're done! If you are the type of person that keeps a fresh layer of wax or sealant on their car at all times (since you are on this site in the first place, you probably are!), then you don't want to have to re-apply that protection after each wash! Luckily, MetroVac Car Shampoo is designed with a pH neutral formula that won't break-down or tarnish the protection product you currently have on your paint, just the dirt and road grime that is sitting on top of it! Another fantastic feature of the MetroVac Car Shampoo is how much easier it is sure to make your washing routine. This is thanks to the fact that MetroVac Car Shampoo is formulated to rinse clean once you are done washing. This will greatly reduce the risk of left over residue, water spots, or streaks that tend to occur with some other brands of car shampoos. 16 oz.
