Nielsen Pre Wash

By softening and lifting heavy soiling before contact washing, it reduces the risk of swirls, preserves protective coatings, and speeds up your entire wash process. Versatile, silicone-free, and NTA-free, it works effortlessly through trigger spray, low-pressure application, and snow foam systems. Whether you’re cleaning a commercial fleet, prepping a daily driver, or caring for wrapped vehicles, Nielsen Pre-Wash gives you a cleaner, safer start, every time.

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.

Q5: Can I use Nielsen Pre-Wash on all vehicle types, including commercial fleets?
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.
