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.

## Questions & Answers

**Q: can you explain how to dilute the product?**
A: don't dilute
Merely use a small half cap full .........lots of soap

**Q: Is this safe to use on bmw's frozen paint? the paint is matted and was ceramic coated with g1 crystal laquer.**
A: Yes. The clear on "frozen" finishes meet the same standards, and G Wash is recommended for use with their coatings.

**Q: Is this body shop safe ? Can I use this in fresh paint .. and are there any silicones in it**
A: As far as I know it is since they are no abrasive in it however just to be sure you can contact a ceramic pro coating specialist, go on youtube  or just google it.  I use it because I had my car ceramic coated and it does not damage the coating. I would have to say it is safe to use after the paint is cured.

**Q: How much do you add to a foam cannon? My chemical guys Cannon has a line on the side but it seems like a ton of product.**
A: Check your settings. There are also inserts to reduce the amount of water going through the cannon to make soap use efficient if you have too powerful of a pressure washer

### ⭐⭐⭐⭐⭐ 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.
