Gtechniq Customer Care Guide


Your car has now been prepared to the Gtechniq standard by an authorised service professional.

But did you know, with just a little care and effort it’s easy to keep it this way indefinitely?

The coatings applied to your car mean that as well as looking great you also get incredibly low maintenance Smart Surfaces. These require less cleaning, and much less effort to clean.

Ongoing care is simple, easy and rewarding.

This handy guide will help you realise your expectations of the Gtechniq system.

Caring for your car and maintaining your Gtechniq coating:


Products needed: Gtechniq G-Wash shampoo, warm water, 1 microfibre wash mitt, 1 sponge or 2nd wash mitt (for wheels) & a Gtechniq drying towel, either MF2 or MF4.

Avoid washing your car in direct sunlight & always rinse your car thoroughly first.

For best results use the three bucket system, one for wash, one for rinse & one for wheels.

Always begin washing on the upper surfaces (roof, bonnet, boot) and work your way down, rinsing your wash mitt in clean water as you go to release dirt & grit.

Wash the lower sections of the bodywork next with your wash mitt, leaving the wheels until last (using your separate sponge or 2nd wash mitt) as brake dust is highly abrasive.

We recommend using Gtechniq G-Wash shampoo for cleaning your car.

Never apply detergents directly to bodywork or your microfibre wash mitt / sponge.

Never use a real leather chamois for drying, these are too harsh for modern paints and will easily scratch and marr the surface. Microfiber drying cloths are much softer, far more absorbent, and therefore require much less effort.

Don’t scrub or use any force when drying. Simply lay the drying cloth across the surface and pull it towards you.


Bird droppings & other corrosive deposits

Always wash off bird droppings, bat droppings, bug impacts and tree sap as soon as possible, as these can be highly corrosive. Use plenty of clean water to loosen and soften deposits. Always avoid scrubbing or scratching.

Swirl marks

The familiar spider web style patterns of micro-scratches that appear over time on a car’s paintwork are almost entirely caused by the scrub action of washing. The harder you scrub, the more often you do it, the more swirl marks you generate.

The 3S coatings on your car eliminate the need for harsh scrubbing. But if you find that you’re losing the battle, they can easily be removed. Speak to your Gtechniq detailing professional to find the most appropriate product. Gtechniq W2 is a great product to remove any tough spots.

Ongoing care

Hydrophobic (water repelling) surfaces can wear down over time due to the environment. The protective layer will still be there but the beading may be reduced. To extend or re-activate the beading nature of your Gtechniq paint sealant, simply spray Gtechniq C2 onto the paint surface and wipe off the residue with a microfibre cloth. C2 will extend the hydrophobic nature of you C1 Liquid Crystal. We recommend you use the C2 every two months to maintain optimum sealant efficiency.

We recommend an annual professional detail to fix surface wear and tear in the coatings applied to your car, maintaining maximum visual impact and long-term protection.

A maintenance service consists of a professional hand wash and correction of surface damage built up within the coating layer. Your car will be returned looking as good as the first time. The Gtechniq coating’s service life can be extended indefinitely in this way, resulting in cars that look as good as new, indefinitely. Costs of detailing vary between professional Gtechniq licensees.

In between services, it’s really easy to maintain your car in optimum condition inside and out with just a few easy to use products. Speak to your professional about these products.

How to clean your interior surface

Routine cleaning should include a quick vacuuming with a soft brush head. This should be the first step to interior cleaning unless one has a reason to bypass it.

The second step involves a clean towel and a bowl of lukewarm distilled water mixed with an appropriate cleaner. We recommend Gtechniq W2 Universal Cleaner as a safe cleaner, One will also need a separate bucket of water without soap and a third bucket.

The process works like this: dip the towel into the Gtechniq W2 soapy water, wring it out until it is moist but not dripping wet, and then clean the surface. Dip the dirty rag into the water and wring it out into the empty bucket. Repeat the dip and wring process as many times as necessary to ensure that the towel is clean. It may be necessary to refill the water-only bucket more than once to ensure that the towel can be kept clean. Once the towel is clean, commence the procedure again with the next area.

For Leather, Vinyl and Fabric we recommend a 10:1 solution of water and W2 Universal Concentrate Cleaner. For Carpet we recommend 7:1 solution of water to W2 Universal Concentrate Cleaner.
