## 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

## Customer Reviews

### ⭐⭐⭐⭐⭐ Superb Car Shampoo
*by T***E on 2 October 2024*

A little goers a long, long way...Added the recommended 4 capfuls to my ubiquitous Orange Bucket & this Shampoo cleaned our SUV with 1/4 bucket left over.Super Foamy and super Slippery too. Makes Car Cleaning easy, effortless and leaves the car looking great with no streaks & all dirt removed.Highly recommended for those wanting a clean vehicle with minimal effort with a quality product. One of the best I have uses &, although it is not the cheapest, the bottle is going to last a very long time...

### ⭐⭐⭐⭐⭐ Fantastic Car Wash
*by M***T on 30 January 2025*

Really pleased with this shampoo from Gtechniq, along with a lot of their other products. Washes really well even with low concentrations, and best of all, it doesn't leave any residue or streaks. Has been my go-to car wash for a while now.

### ⭐⭐⭐⭐⭐ The best I've used in 30+ years.
*by S***E on 24 November 2018*

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.
