Product Description

Why Use Gtechniq GWash?

GWash is a pH-neutral car shampoo formulated for regular maintenance on vehicles with ceramic coating, wax, or sealant protection. The concentrated formula generates thick foam that lifts dirt particles, road grime, and traffic film from your paint without stripping protective coatings.

Fully biodegradable, this car wash shampoo lubricates dirt and grime during the wash process, minimizing swirl marks and maximizing gloss retention. The high foaming shampoo solution works with the bucket method to deliver a thorough cleaning that keeps your vehicle looking new between professional details. Safe for all exterior paint and protective coatings.

The Gtechniq Difference

At Gtechniq, we develop car maintenance products that work in harmony with protective coatings. GWash exists because standard car wash shampoos often contain detergents that strip wax, sealant, and ceramic coating protection over time.

We ensure our products go through rigorous testing in both lab and real-world conditions before reaching our users. The pH-neutral formula cleans effectively without degrading the hydrophobic effect of your existing protection. GWash gives vehicle owners and professional detailers a car wash soap they can trust for maintenance washes without compromising the coatings they’ve invested in.

Customer Testimonials and Reviews

James R.

"I am extremely picky about the appearance of my black vehicle and have been blown away at how Gtechniq products leave my car the deepest glossiest black I have ever seen! Just the Gwash alone is by far the most impressive car wash I have ever used. I have switched over to everything Gtechniq makes. The prices are extremely reasonable too! Here are gwash results on my 1999 z with original paint."

Robert Tansy

"After taking delivery of our 2023 Corvette in February I had the 9 year ceramic coating applied, including all glass, wheels coated inside and out. Have been using all Gtechniq cleaning products including bug remover, citrus foam, gwash, ceramic sealant, quick detailer and perfect glass cleaner. After 9000 miles the car looks like it just rolled out of the showroom. Every Gtechniq product I have used I am very thankful for the results. Great products!!"

Jason Fladoos

"Nathan was super insightful. The G wash made a huge difference compared to the other soap I was using for my ceramic coat. Gtechniq products really do make a difference." - Jason Fladoos "Very good car soap and foaming is amazing."

"Very good car soap and foaming is amazing."

Frequently Asked Questions

Can I use GWash on a car with wax or ceramic coating?

Yes. GWash is a pH-neutral shampoo formulated to be safe on all surfaces, including vehicles with ceramic coating, wax, or sealant protection. The pH-neutral formula cleans without stripping your existing protection.

How long does GWash last after opening?

GWash maintains its cleaning properties for up to 12 months after opening when stored properly in a cool, dry place. Keep the cap tightly sealed after each use.

Can I use GWash with a foam cannon or foam gun?

GWash is not designed for use in a foam cannon. The instructions call for the bucket method with a wash mitt. If you want a product for foam cannon use, we recommend Gtechniq W4 Citrus Foam instead.

How much GWash do I need per wash?

For light soiling and regular maintenance, use two caps (20ml) per 5-gallon wash bucket. For heavy soiling with road film, bird droppings, or built-up grime, use four caps (40ml).

Will GWash cause water spots?

Rinse your vehicle thoroughly with clean water after washing and dry promptly to prevent water spots. Avoid washing in direct sunlight, as this can cause the shampoo solution to dry on the surface before rinsing.
