A luxurious blend of super concentrated surfactants, emulsifiers and lubricants will gently and effectively clean the paint whilst being safe to use on waxes, sealants and coatings.

Instructions

HOW TO USE

1. Shake well before use. Dilute 10ml for a moderately dirty car in a 4-5 gallon bucket. Use 15ml for a heavily soiled car for extra cleaning power, suds and lubrication.

2. Pre-rinse the car to remove any loose dirt with high pressured water.

3. Wash the car with a mitt or wash pad starting from the top, working down to ensure the dirtiest parts of the car are washed last.

4. Rinse thoroughly.

FOR BEST RESULTS

1. Use the two bucket wash method, with a wash and a rinse bucket including grit guards. Agitate the wash solution with high pressured water to produce rich luxurious foam.

2. Work one panel at a time working in straight lines.

3. /ONE: Car Shampoo V4 is high foaming and can be used through a foam lance to provide additional lubrication — a 1:9 ratio is ideal.

4. Use a GT /ONE: Wash Pad or /ONE: Wash Mitt. The large surface area and soft microfibre yarn makes washing more efficient and enjoyable.
