Gtechniq - W4 Citrus Foam - High Content Foaming Agent, Removes Dirt and Road Grime, Non-Caustic Formula, Maximum Gloss Retention Snow Foam (5 Liter)

It's honestly one of the if best Prewash out there it honestly took of any option 95 percent of the junk of my vehicles. Guys it's a really good product. In closing this prewash is legit and it's functioning works!!!

Their line of car wash items are great. I use it on both my cars. Products are good quality. Foams well and removes media effectively.Their shipping and packaging is on point.25 G80 M3 MT22 Etron sportback95% of of my car wash supplies come from Gtecniq. Definitely recommend.

Product is great, Amazon packaging is trash. This is the replacement for the first bottle that was crushed and leaking in the same spots. At this point I'll keep it and move it to another bottle, but Id order directly from the company site and skip Amazon.

I have been doing Rinseless wash, so never had any chance of visiting foam town!I always though, it's kinda gimmicky. But, after using this for the first time, it looks so clean!Specially, I like the fact that it clings to the surface. Let it dwell for 3/4 minutes before washing it off, otherwise it won't be effective much.Gtechniq is always my first choice when I shop around as my car has Gtechniq crystal serum ultra. This one works very good with the ceramic coating.Smells good, also the price is reasonable. It doesn't add any protection, and that's also a positive thing.

Excellent wash. Sprayed on as a pre-wash with a hand pump sprayer and it performed wonderfully. Will buy again. This wash is aggressive, wear Gloves! I will buy again

Great product to use as a prewash! The smell is great! & being able to use it in a foam gun is easy!

Pricey but works really well with my ceramic coated car. I would buy it again if I find it for a good deal.

Best car wash that I have found. My truck is coated with gtechniq coating and this soap works very well. Love the smell too.
