Full Description

Duel Assault pre-wash snow foam

An exceptional pre-wash product that is designed to provide high-intensity cleaning power and thick foam to remove even the toughest road grime. This product is perfect for those who want to protect their vehicle's existing wax or sealant, as it is safe to use on these protective coatings.

One of the key benefits of Assault pre-wash snow foam is its super foamy formula, which creates a thick layer of foam that clings to the surface of your vehicle. This foam helps to loosen and remove dirt, grime, and other contaminants that can damage your car's finish.

Additionally, the product has excellent cleaning power that effectively removes all types of dirt and grime, leaving your vehicle looking clean and fresh. Its long dwell times allow the foam to penetrate the dirt and grime, making it easier to remove during the rinse.

Another significant advantage of Assault pre-wash snow foam is its ability to clean your car without harming its existing wax or sealant. This feature makes it ideal for those who have already invested in protective coatings for their vehicle and want to maintain them.

Finally, the product has a pleasant apple scent that makes using it a more enjoyable experience.

Expert Notes

Duel Autocare's Assault is an alkaline pre-wash snow foam with an apple scent, designed to cling to painted panels as a thick foam while it dwells and softens road grime and traffic film before the contact wash. It carries a pH of around 11 to 12, mixes at 50ml of product to 450ml of water in a foam lance, and is stated safe on existing wax and sealants, making it a suitable regular first step for a two stage wash. It suits anyone with a foam lance or foam cannon who wants a proper pre-wash on a car with light to moderate road grime. Pair it with a wash mitt, a two bucket wash method and a shampoo for the contact wash that follows.

  • Glass
  • Plastic trim
  • Rubber seals
