Product Information
How to use

- Concentrated for performance and economy
- Silicone Free

How to use
1. Mix 1 part Nielsen Pre-Wash to 10 parts clean water (or follow the “safe dilution” label for foam vs spray).
2. Apply to a pre-wet surface to help distribute the chemical more evenly.
3. Trigger spray: for spot treatment or smaller vehicle use.
4. Low-pressure spray/snow foam: for full front and surfaces to allow good dwell time.
5. Allow approximately five minutes dwell time, just enough for the formula to break down grime, but never let it dry on the surface. Drying could lead to streaks or stains, especially on trim or sensitive paint.
6. Use clean water with a pressure washer or high-volume hose. Rinse top-down to avoid dirty water running back over clean areas.
7. After the pre-wash rinse, move into a full contact wash with shampoo or soap to fully clean the surface, then finish with your usual drying/protection steps.
Pro Tips for Best Results
✅ Use snow foam where possible: it helps extend the dwell time and reduces the chance of drying.
✅ Work on shaded surfaces or early morning/evening so the product doesn’t evaporate too quickly.
✅ Use separate cloths or mitts for wheels or bug-heavy areas to avoid cross-contamination of grime.
✅ Always rinse thoroughly: trapped cleaner or residue can dull the shine.
Frequently Asked Questions (FAQs)
Q1: Is Nielsen Pre-Wash safe on wraps, livery, and sensitive trims?
Yes, its non-caustic, silicone-free, and NTA-free formula is engineered to clean without damaging vinyl wraps, painted graphics, plastic trims, or delicate finishes.
Q2: What dilution should I use for general vehicle pre-washing?
A common ratio is 1:10 (one part product to ten parts water). You can adjust slightly based on the level of dirt, but avoid over-concentrating to prevent waste or streaking.
Q3: Can I use Nielsen Pre-Wash in a snow foam lance?
Absolutely. It performs exceptionally well in snow foam and low-pressure systems, helping extend dwell time and improving dirt softening before rinsing.
Q4: Will it remove wax, sealants, or ceramic coatings?
No, the formula is non-caustic and designed to clean without stripping protective layers. It helps preserve wax longevity by removing contaminants that degrade finishes.

Yes, it’s ideal for fleets, coaches, vans, bikes, boats, and household vehicles, especially those with heavy road film or bug contamination.
Q6: Should I apply it to a dry or wet surface?
For best results, pre-wet the surface. This helps the product spread evenly and prevents rapid drying, especially in warm weather.
Q7: How long should I leave it on before rinsing?
Allow around five minutes dwell time, but never let it dry. Work in shade where possible.
Q8: Is it suitable for regular weekly use?
Yes, it’s gentle enough for frequent maintenance while still strong enough for heavily soiled areas.
