Gtechniq GWash Shampoo
GWash Car Shampoo from Gtechniq is a premium, highly concentrated cleaning solution formulated to deliver a deep, effective clean while preserving and enhancing your vehicle's protective coatings. Designed specifically for use with ceramic coatings, GWash removes dirt, road grime, and contaminants without compromising the hydrophobic properties or durability of your vehicle's protective layer.
This advanced car shampoo creates a high-foaming lather that encapsulates dirt particles, reducing the risk of swirl marks and scratches during washing. Its pH-neutral formula ensures it is safe for all exterior surfaces, including paint, glass, and trim. Gtechniq GWash Car Shampoo is gentle yet effective, making it ideal for regular maintenance washes to keep your vehicle in pristine condition.
With just 20ml of product required per wash, Gtechniq GWash is both economical and environmentally friendly. Its easy-rinse formula ensures no residue is left behind, leaving your car spotless with a streak-free finish. The shampoo is also biodegradable, aligning with eco-conscious car care practices.
Used in conjunction with Gtechniq ceramic coatings Gtechniq GWash will ensure maximum gloss retention. Or should you be wishing to use a shampoo which boosts the ceramic effect on paint, then we'd recommend trying the new Gtechniq W3 Ceramic GWash
Available in 250ml, 500ml, 1 litre & 5 Litre Bottles
How to use Gtechniq GWash W1 Car Shampoo
Shake well before use
Use out of direct sunlight
Add two caps (20ml) for light dirt, or four caps (40ml) for heavy dirt, into an empty 5 gallon (23 litre) wash bucket
Fill bucket with water, for best results use warm water
Always begin washing the upper surfaces of your car and work downwards. We recommend using a Gtechniq Microfibres wash mitt
After use, rinse your car thoroughly with clean water to remove all surfactants.
Store in a cool, dry place
Use within 12 months of opening
Always begin washing the upper surfaces and work your way down, rinsing your wash mitt in a separate bucket of water as you go to release dirt and then replenish your mitt in a second bucket containing your dilution of water and G-Wash. Brake dust is highly abrasive so ideally use another mitt for cleaning your wheels. Ensure that you never press hard to remove dirt (for stubborn dirt, allow to soak for several minutes) and always rinse your car thoroughly to remove all soap residues. Never apply detergents directly to bodywork or your sponge.
Our Take
“Why we use this when we want proper cleaning power without compromising protection.”
GWash is one of those shampoos we’ve come to trust when we’re maintaining coated or well-protected cars but still want meaningful cleaning performance. It’s pH neutral, but unlike some gentler maintenance shampoos, it has enough bite to properly shift road film and everyday grime without feeling weak.
Technically, Gtechniq formulated it to offer high levels of lubrication and controlled dirt release, which is what we notice most in use. The mitt glides well across the surface, foam remains stable in the bucket, and it rinses cleanly without leaving gloss enhancers or masking agents behind. That’s important to us because we want to see exactly how the existing protection is behaving after the wash.
We also like that it’s been designed specifically with ceramic coatings in mind. It cleans effectively but doesn’t interfere with hydrophobic performance, which makes it a very safe choice for coated vehicles.
For us, GWash sits in that sweet spot between gentle maintenance shampoo and deeper-cleaning wash. If we want reliable cleaning, excellent glide, and protection-friendly performance in one product, this is a very solid option.
