## Description

Introducing the Gtechniq W1 GWash Car Shampoo Cleaner, a high foam content product that is designed to provide an unbeatable clean for your car. GWash Shampoo breaks the bond between the dirt film and your vehicle’s paintwork and lubricates dirt particles, while at the same time minimising surface abrasion for a clinically clean finish.High Quality Foam ContentWhen you wash your car with GWash, you’ll find that it produces a high foam suds content. This high content promotes the breakdown of the bond between the dirt film and your vehicle’s paintwork. It makes it much easier to clean the dirt and grime from everyday use from your car. Works with Any Gtechniq CoatingWhen you use W1 GWash, you can rest assured that it will not negatively impact your Gtechniq coating or sealant that you have already applied, as GWash has been specifically formulated with a 100% biodegradable, pH neutral formula that works in harmony with Gtechniq’s range of coatings. Retains GlossIf you have applied T1 Tyre and Trim, T2 Tyre Dressing, Quick Detailer, Panel Wipe or a number of gloss boosting products by Gtechniq (all available on desertcart), then usng GWash Shampoo will ensure maximum gloss retention through the excellent lubrication of dirt particles, which in turn minimises the surface abrasion, and promotes gloss retention.Easy To UseShake product well before using this product, and do not apply in direct sunlight. Add two caps (20ml) for light dirt, or four caps (40ml) for heavy dirt, into an empty bucket, and fill bucket with water (for best results use warm water). Start washing from the upper surfaces of your car and work downwards, and when finished, rinse thoroughly with clean water to remove all surfactants.Store in a cool, dry place – Use within 12 months of opening.

Review: Premium Car Shampoo That Truly Delivers Professional Results - I've tried countless car shampoos, but Gtechniq's W1 GWash has completely transformed my detailing routine. After receiving a sample pack at a car show, I was immediately impressed by the product's performance. What sets this shampoo apart: Ultra-concentrated formula means a little goes a long way Exceptional cleaning power without stripping wax or sealants pH-neutral formula that's gentle on paintwork Creates incredible lubrication for safe, scratch-free washing Leaves an immaculate, streak-free finish I've used this on my 911 and several other vehicles, and the results are consistently outstanding. The suds are rich and thick, making the washing process not just effective but enjoyable. Whether you're a car enthusiast or just want a professional-grade clean, Gtechniq W1 GWash is a game-changer. Highly recommended for anyone serious about maintaining their vehicle's appearance. Pros: Professional-grade performance Economical concentrate Safe for all paint types Cons: Slightly more expensive than standard car shampoos (but worth every penny)
Review: 5-Star Review: Gtechniq W1 Auto Wash – A Premium Car Shampoo That Delivers - I’ve been using Gtechniq W1 Auto Wash for several weeks now, and it’s quickly become one of my go-to car shampoos. As someone who takes pride in maintaining their vehicle properly, I look for products that offer great cleaning power without compromising paint protection—and W1 delivers on all fronts. This shampoo produces low suds, which may surprise those used to thick foaming shampoos, but don’t be fooled—its cleaning performance is excellent. It effortlessly lifts dirt and road grime without needing excessive product, meaning a little goes a long way. It rinses cleanly with no residue, leaving behind a spotless, streak-free finish that really enhances the appearance of the paint. One of the standout features is that it’s completely wax and sealant-safe, making it perfect for maintaining ceramic coatings or synthetic sealants without breaking them down. It’s also highly concentrated, so you only need a small amount per bucket, adding to the overall value. If I had to mention a minor point, it would be that because it’s a low-suds formula, it doesn’t offer the “foamy wash” experience some enthusiasts enjoy—but this is purely personal preference and doesn’t impact its cleaning power at all. Overall, Gtechniq W1 Auto Wash is a professional-grade shampoo that does exactly what it claims. It’s a high-performing, no-nonsense product that works brilliantly for regular maintenance washes. I’ll definitely be buying it again and would recommend it to anyone serious about proper car care.

### ⭐⭐⭐⭐⭐ Lovely clean and lots of bubbles
*by R***R on 29 July 2025*

You don't need a lot in the bucket to get a really good foamy lather for the cleaning stage of your wash. Two capfuls in a large bucket, whizz it up with the jetwash and you're all set. I spray the foam on the car and while I'm waiting for that to do it's thing I make this up in the bucket and by the time I've rinsed the foam and do the wash this is still full of bubbles. It might be expensive for the size of the bottle but it does a quality job of cleaning and it value for money when you consider how little you actually need for each wash.
