All-in-One Cleaning & Protection
W3 Ceramic GWash is designed to clean the vehicle while simultaneously leaving behind a protective ceramic layer.
This makes it ideal for owners who want to combine:
- Contact washing
- Hydrophobic protection
- Maintenance coating
into one straightforward process.
High Lubrication
The formula provides strong lubrication between the wash mitt and paintwork.
This helps the mitt glide across the surface more easily while dirt particles are lifted and captured.
Good lubrication helps reduce the risk of:
- Fine scratches
- Swirls
- Wash marring
when used with correct washing technique.
Low-Suds Formula
W3 uses a low-suds formulation.
Rather than relying on excessive foam, the product focuses on lubrication, cleaning efficiency and ceramic deposition.
Low foam does not mean low cleaning power.
Dirt-Repellent Finish
After washing, the ceramic ingredients leave behind a surface designed to repel contamination more effectively.
This can help:
- Reduce dirt adhesion
- Improve maintenance washing
- Keep the vehicle cleaner for longer
Hydrophobic Protection
W3 leaves behind a water-repellent coating that improves how water behaves on the surface.
This can result in:
- Stronger beading
- Faster sheeting
- Easier rinsing
- Faster drying
Safe for Matt & Satin Finishes
Unlike some gloss-enhancing shampoos, W3 is suitable for matt and satin finishes.
This makes it a more versatile choice for vehicles with non-gloss paintwork.
Highly Concentrated Formula
For normal washing, Gtechniq recommends:
- 20ml of product
- Per 10 litres of water
This makes a 500ml bottle capable of delivering many maintenance washes.
How to Use Gtechniq W3 Ceramic GWash
- Shake the bottle well before use.
- Use out of direct sunlight.
- Ensure the vehicle surface is cold.
- Add 20ml of W3 to an empty wash bucket.
- Add 10 litres of cold water.
- Begin washing from the upper surfaces and work downwards.
- Rinse the wash mitt thoroughly in cold water after dirty panels.
- Continue around the vehicle.
- Rinse the vehicle thoroughly with clean cold water.
- Ensure all surfactants are fully removed.
Why Use Cold Water?
Gtechniq specifically recommends cold water for:
- Mixing
- Mitt rinsing
- Final rinsing
This helps the product perform consistently and reduces the chance of the ceramic content interacting poorly with heat.
Start from the Top
Always begin with the cleaner upper panels and work downwards.
This helps avoid transferring heavier contamination from lower sections onto cleaner areas.
Rinse the Wash Mitt Thoroughly
After cleaning dirtier panels, rinse the wash mitt thoroughly in cold water.
This is particularly important with ceramic shampoos, as contamination should not remain trapped within the fibres.
Enhanced Hydrophobic Protection
W3 can also be used for an additional hydrophobic boost.
For this method:
- Use no more than 10ml of product
- Apply a small amount directly to a WM2 Microfibre Wash Mitt
- Work one panel at a time
- Rinse the mitt thoroughly after dirty sections
- Rinse the vehicle completely with cold water afterwards
This method helps maximise the ceramic protection left behind.
Suitable for Maintenance Washing
W3 works particularly well for:
- Weekly washing
- Fortnightly maintenance
- Ceramic-coated vehicles
- Protected daily drivers
- Show cars
- Matt or satin-finished cars
Helps Maintain Existing Protection
W3 can be used as part of a broader ceramic maintenance routine, helping refresh hydrophobic behaviour while the vehicle is being washed.
Do Not Use in Direct Sunlight
Avoid using W3 in direct sunlight or on hot surfaces.
For best results:
- Work in shade
- Use cold panels
- Avoid excessive heat
- Rinse thoroughly
Storage
Gtechniq recommends:
- Storing in a cool, dry place
- Using within 12 months of opening
