Gtechniq Multi Purpose Cleaner Concentrate
Gtechniq W2 Universal Cleaner Concentrate is a powerful, task-focused cleaner formulated to remove stubborn stains and heavy soiling across multiple surfaces.
Key Benefits
- High-Impact Cleaning: Effectively tackles tough stains such as biro marks, food spills, and ingrained grime.
- Multi-Surface Capability: Suitable for fabrics, carpets, tyres, and engine bays.
- Flexible Dilution: Use neat for stubborn contamination or dilute for lighter cleaning tasks.
- Targeted Use Formula: Designed for intensive cleaning rather than day-to-day maintenance.
- Concentrated Value: Economical concentrate delivers strong performance with minimal product.
How to Use
- Assess: Identify the surface and level of soiling to determine dilution or neat use.
- Apply: Spray W2 directly onto the affected area.
- Dwell: Allow a short dwell time to let the cleaner break down contamination.
- Agitate: Lightly agitate with a suitable brush or microfiber towel.
- Remove: Wipe or rinse thoroughly to remove loosened residue.
PRO TIP: Always test on an inconspicuous area first and avoid use on leather or for routine maintenance cleaning. W2 is best reserved for stubborn problem areas where stronger cleaning power is required.
Dilution calculator
Pick your container and your ratio, and read off how much concentrate to pour.
A foam cannon does not spray its bottle. It draws from the bottle into the pressure washer's flow, so a 1 L bottle can put 11 L on the car and the ratio in the bottle tells you nothing about what reaches the paint. Measure your setup once and the number holds for every product that quotes a PIR.
Nothing matches that. Check the product's own page for its ratio.
Common questions
-
Parts water to one part product. A 10:1 mix is ten parts water and one part product, so a 1 L bottle takes 91 ml of product and 909 ml of water. A few brands print theirs the other way round, so check the label if a number looks unusually strong.
-
Water first, then the concentrate. Pouring concentrate into an empty bottle and topping it up makes it foam over the top, and you lose some of what you just measured.
-
Most diluted products keep for a few weeks in a sealed, labelled bottle out of sunlight. Write the product and the ratio on the bottle. An unlabelled trigger bottle is how the wrong chemical ends up on someone's interior.
-
Panel Impact Ratio is the concentrate as a percentage of everything leaving a foam cannon, the bottle water and the pressure washer water together. It matters for snow foam and pre-wash only, because a cannon draws from its bottle into the washer's flow rather than spraying the bottle.
-
A syringe or a measuring jug with millilitre graduations. Capfuls vary by bottle and by how full you fill them, and at 256:1 a few millilitres out is a noticeable change in strength.
