Gtechniq Auto W1 GWash Cleaner for Cars, Dirt and Stain Remover, Pink Grapefruit Fragrance, 100% Biodegradable - 250ml

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)

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.

Very good stuff especially since I'm living in London area leaving water spots everywhere after washing with cheap shampoo (Halfords own brand, etc) you don't need much mix with water in a bucket & the result was amazing 👍

Good gloopy and concentrated shampoo that seems to work very effectively. However, it lacks any scent which reviews from a few years back suggested it had. Several car shampoos I've tried no longer have the scent they once had. I didn't realise how much I'd miss the scent of my turtle wax zip wax shampoo which was also good at cleaning.

You have to use very little o fit to do a FANTASTIC job!!

The best car shampoo there is. Even my neighbours commented how nice and shiny my car looked after washing it with this. Didnt even nbeed the wax.

I have a car with GTechniq coatings, recommended and applied by a GTechniq approved detailing company. It is actually the third car I've owned and had professionally detailed with their sealants. That probably tells you how much I rate their products to begin with. However, over the years I've always taken care of the weekly washing of cars myself and used a variety of brands. All would be what you'd call premium wash products from well-known brands and they've all done a reasonably good job (some better than others). What none of them have done is enough to impress me like the GTechniq W1 GWash has. It is ridiculously slick and gloriously fragrant when applied to a car with a lambswool wash mitt. It lasts far, far longer than I would have anticipated too. The suds it generates are more in volume than anything else I've used and there is a genuinely 'slide' and non-abrasive feel about how well it washes, even on a heavily soiled car that had been lance washed with snowfoam and then jet-washed off. The shine, although I appreciate I am talking about this for a car already detailed to a high shine, is superb. The finish was streak-free with no signs of overly-fast water streaking or marks of any kind whatsoever. I couldn't recommend it highly enough. It is worth every penny and will probably save you money in the long run because of how long it'll last.

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.

Uno dei migliori shampoo per auto mai provato. Ben lubrificato, ottimo potere pulente, delicato verso cere e protezioni. Poca schiuma ma la lubrificazione è comunque ben presente. Utilizzato in diluizione 1:1000.

Best Car Wash I’ve ever used it removes dirt and sand really quick and helps maintain my car and looks like brand new. I don’t remember. the product definitely lasted with me for more than 40 washes.

The thick, luxurious foam it produces clings to the surface, ensuring thorough coverage and allowing the cleaning agents to work their magic. This not only makes the washing process more enjoyable but also contributes to a more efficient and effective clean. I also appreciate the attention to detail in the formulation of G-Wash. It is pH-neutral, which means it won't harm any existing wax or ceramic coatings on my car. In fact, I've noticed that it enhances the longevity of these protective layers, keeping my vehicle looking pristine for longer periods. The pleasant scent of G-Wash is an added bonus, making the entire car washing experience more enjoyable. It leaves a subtle and refreshing fragrance that lingers, giving my car that just-detailed feel every time. In conclusion, Gtechnic G-Wash has become an integral part of my car care routine.

Only products I use on my car with Qtechniq Ceramic coating. Top of the line and priced well. Best investment made.

Constatations après 1er essai effectué par temps couvert sur 2 vehicules. Les salissures partent avec facilité, sans frottement excessif. Sur peinture métal 3008, résultat après séchage excellent. Chromes parfaits. Sur peinture mate Fiat 500, l'essuyage est difficile et des traces subsistent. Coclusion : le produit gagne à être maitrisé car il est excellent.
