Is Gtechniq GWash safe to use on cars that don't have a ceramic coating?

Absolutely. Whilst it is specially formulated to maintain Gtechniq coatings, its gentle, high-lubrication formula is perfect for cleaning any unprotected or waxed paintwork without causing surface abrasion.

Can I use GWash in a snow foam lance?

Whilst GWash is designed primarily as a bucket wash shampoo to provide lubrication during the contact wash stage, you can add a small amount to a snow foam lance for extra suds. However, a dedicated pre-wash foam is typically recommended for the best touchless cleaning results.

Will this shampoo strip my existing wax or sealant?

No, GWash is a pH-neutral, gentle formula. It is specifically designed to clean effectively without stripping existing waxes, sealants, or ceramic coatings, ensuring your vehicle's protection remains intact.

Why is it recommended to use warm water?

Using warm water helps to fully activate the surfactants within the shampoo, creating a richer, thicker foam and improving the overall cleaning power and dirt-lifting capabilities of the product.

Description

Engineered for Ultimate Gloss Retention
Gtechniq GWash W1 Shampoo is the ideal solution for both professional detailers and dedicated motoring enthusiasts seeking a safe, effective maintenance wash. When washing a vehicle, the friction caused by removing dirt is the leading cause of swirl marks and dulling paintwork. GWash addresses this directly by providing exceptional lubrication, encapsulating grit and grime so it can be safely glided away from the clear coat. This process not only ensures a thorough clean but fundamentally preserves the vehicle’s high-gloss finish.

Perfect Harmony with Protective Coatings
For vehicles treated with advanced ceramic or composite coatings, selecting the right shampoo is critical. GWash has been meticulously formulated to complement the Gtechniq range of sealants and coatings. It contains no harsh chemicals or aggressive detergents that could strip or degrade your existing protection. Instead, it gently cleanses the surface, reviving the hydrophobic properties and visual depth of the underlying coating.

Highly Concentrated and Cost-Effective
A little goes a long way with GWash. The highly concentrated formula means you only need a couple of capfuls per bucket to generate an abundance of rich, cleaning suds. Whether you are tackling light dust from a weekend drive or heavy, baked-on dirt from the winter roads, the dilution ratio can be easily adjusted to suit the task at hand, providing excellent value for everyday drivers and busy tradespeople alike.

Application Instructions

Ensure the vehicle is parked out of direct sunlight and the paintwork is cool to the touch. Shake the bottle well before use.

Add two caps (20ml) of GWash for light dirt, or four caps (40ml) for heavy dirt, into an empty 5-gallon (23-litre) wash bucket.

Fill the bucket with water, preferably warm, for the best results and to activate the high-foaming properties.

Using a high-quality wash mitt, always begin washing the upper surfaces of your vehicle and work downwards to prevent cross-contamination of dirtier lower areas.

After thoroughly washing, rinse the vehicle completely with clean water to remove all surfactants and dry with a premium microfibre towel.

Store in a cool, dry place and use within 12 months of opening.
