Heavy-Duty Pre-Wash Cleaning
Assault is designed to remove as much contamination as possible before the wash mitt touches the vehicle.
This helps loosen:
- Road grime
- Traffic film
- Mud
- General dirt
- Winter contamination
Removing more of this contamination during the pre-wash stage can make the following contact wash safer and easier.
Thick Foam
Assault creates a thick layer of foam across the vehicle.
Dense foam helps keep the cleaning solution in contact with the surface for longer, giving the product more time to break down contamination.
This makes it particularly useful on heavily soiled vehicles.
Long Dwell Time
Longer dwell time gives the cleaning agents more opportunity to work.
Rather than immediately running from vertical panels, Assault is designed to cling to the vehicle and remain active for longer.
This can improve cleaning performance on:
- Lower doors
- Side skirts
- Rear bumpers
- Wheel arches
- Other heavily contaminated areas
Safe on Wax & Sealants
Despite its strong cleaning performance, Assault is designed to be safe on existing wax and sealant protection when used correctly.
This makes it suitable for protected vehicles that still need a more powerful pre-wash.
Helps Make Contact Washing Safer
The pre-wash stage is important because loose contamination can become trapped between the wash mitt and paintwork.
Dragging dirt across the surface can contribute to:
- Swirls
- Fine scratches
- Wash marring
Using Assault first helps reduce the amount of contamination remaining before physical contact.
Ideal for Winter
Assault is particularly useful during winter when vehicles often collect heavier contamination.
Typical winter grime includes:
- Wet road dirt
- Salt
- Mud
- Traffic film
- Lower-panel contamination
Its stronger cleaning action makes it well suited to these conditions.
Ideal for Heavily Soiled Vehicles
Assault works well on:
- Daily drivers
- Cars used in poor weather
- Vehicles that have gone longer between washes
- Performance cars
- Winter-driven cars
For lighter maintenance, a milder snow foam may be sufficient.
Apple Scent
Assault features a fresh apple fragrance, making the pre-wash process more pleasant without affecting the product’s cleaning performance.
Recommended Dilution
Duel recommends using:
- 50ml Assault
- 450ml water
per vehicle in a snow foam lance bottle.
This gives approximately 500ml of ready-to-use foam solution.
How to Use Duel Autocare Assault
- Add 50ml of Assault to your snow foam lance bottle.
- Add 450ml of water.
- Mix as required.
- Apply evenly across the entire exterior.
- Agitate with a Duel detailing brush where needed.
- Allow the product to dwell.
- Rinse thoroughly with a pressure washer.
Agitate Where Needed
Although Assault is designed to provide strong contactless cleaning, some areas may benefit from light agitation.
Suitable areas could include:
- Grilles
- Badges
- Fuel filler areas
- Trim gaps
- Intricate exterior details
Use a suitable detailing brush and avoid aggressive contact on delicate surfaces.
Do Not Allow to Dry
Never allow Assault to dry on the vehicle.
Dried pre-wash chemicals can leave residue and may affect the finish.
Always monitor the product while it dwells and rinse before drying begins.
Take Care in Direct Sunlight
Extra care should be taken when using Assault in direct sunlight or warm conditions.
Heat can cause the product to dry more quickly.
For best results:
- Work in the shade where possible
- Apply to cool surfaces
- Reduce dwell time in hot conditions
- Rinse thoroughly
Ideal Before Contact Washing
A typical wash process could be:
- Apply Assault pre-wash snow foam.
- Allow it to dwell.
- Rinse thoroughly.
- Carry out the contact wash.
- Rinse again.
- Dry and protect as required.
This helps create a cleaner surface before the wash mitt is introduced.
Suitable for Full Exterior Application
Assault can be applied across the entire vehicle exterior.
This makes it easy to use as a complete pre-wash step before shampooing.
Excellent for Lower Panels
Lower areas generally collect the most contamination.
Assault is particularly effective on:
- Lower doors
- Side skirts
- Rear quarters
- Rear bumper
- Lower front bumper
where road grime tends to build up most heavily.
