Full Description
Stjärnagloss Först X Concentrated Citrus Pre-Wash is a powerful exterior pre-cleaner designed to tackle road grime, traffic film and stubborn contamination before your contact wash.
The concentrated formula makes Först X ideal when your vehicle needs more cleaning power than a normal maintenance pre-wash, particularly during the wet autumn and winter months when vehicles quickly become covered in road dirt and grime.
Powerful Pre-Wash Cleaning
A thorough pre-wash helps remove as much contamination as possible before a wash mitt touches the paintwork.
Först X works on stubborn exterior grime so it can be rinsed away before contact washing, helping reduce the amount of dirt dragged across your vehicle’s paint.
It’s an excellent first stage for heavily soiled cars, vans, SUVs and other vehicles.

How to Use Först X
Dilute Stjärnagloss Först X according to the manufacturer’s recommended dilution for the level of cleaning required.
Apply to the vehicle, concentrating on heavily contaminated areas such as lower doors, bumpers, sills and the rear of the vehicle.
Allow the product time to work without letting it dry on the surface, then rinse thoroughly with a pressure washer.
Follow with Stjärnagloss Snö Snow Foam where required before completing your contact wash with Stjärnagloss Bubblor pH Neutral Car Shampoo.
Always use on a cool surface and avoid allowing the product to dry.
Ideal for Autumn & Winter Detailing
Först X really comes into its own when vehicles are exposed to wet roads, heavy grime and winter contamination.
Its concentrated cleaning ability makes it a useful addition to your detailing setup when a standard maintenance wash simply isn’t enough.

Use 1:1 or weaker on fully cured ceramic coatings. Never allow the solution to dry.
