Your Coating Is Only as Good As How You Maintain It.
A ceramic coating is a long-term investment, but it requires the right care to perform at its best for its full lifespan. Here's exactly how to maintain a coated car on the Sunshine Coast.
What maintenance actually means for a coated car.
A common misconception is that a ceramic coating means you never have to wash your car. That's not true.
What a coating does is make washing easier, reduce how often you need to do it, and protect the paint during and between washes. It doesn't make dirt disappear.
It comes down to three things: washing correctly, avoiding what degrades the coating, and periodic top-up treatments to maintain performance. Get these right and you give the coating the best chance of performing for its full rated lifespan. Get them wrong and you'll degrade it significantly faster.
The right way to wash a coated car.
Pre-rinse thoroughly
Rinse the car completely before touching it. This removes loose dirt and reduces the risk of scratching during the wash.
Use a pH neutral shampoo
Alkaline or acidic shampoos will break down the coating over time. Use a dedicated pH neutral car shampoo, not dish soap or household cleaners.
Two bucket method
One bucket of shampoo solution, one bucket of clean rinse water. Rinse your wash mitt in the clean bucket before reloading with suds. This prevents dirt from being dragged back across the paint.
Microfibre mitt only
Use a high-quality microfibre wash mitt. Sponges and cheap mitts trap grit against the surface and introduce scratches.
Dry with a clean microfibre towel
Don't let the car air dry — water spots will form, especially in Queensland heat. Use a clean, plush microfibre drying towel and blot rather than drag.
Every pass of the mitt carries what it picked up last time.
With one bucket, the grit you rinse off the mitt goes straight back into the suds you reload from. With two, it settles in the rinse bucket instead of going back onto the paint.
Ready to wash. Each pass drags whatever grit is in the mitt across the panel.

Coating-friendly habits
- ✓pH neutral shampoo every wash
- ✓Two bucket wash method
- ✓Microfibre mitt and drying towel
- ✓Rinse bird droppings off quickly
- ✓Park undercover where possible
- ✓Annual coating inspection and top-up
What degrades coating
- ✕Automatic car washesRotating brushes scratch through to the finish.
- ✕Alkaline or acidic cleaning products
- ✕Dish soap or household detergents
- ✕Leaving bird droppings to sitThey etch.
- ✕Abrasive cloths or sponges
- ✕Polishing spraysThese fill defects temporarily.
Skip the automatic car wash.
A single run through an automatic car wash with rotating brushes can introduce dozens of fine scratches into a coated surface. On a dark car in sunlight, the damage is immediately visible. Avoid them entirely.
Extra considerations for our climate.
Heat, salt and UV speed everything up.
Maintaining a ceramic coating on the Sunshine Coast has a few specific considerations that don't apply in cooler, lower UV climates:
- Bird & bat droppingsEtch faster in hot weather — remove within hours, not days
- Water spotsForm faster in heat — dry thoroughly after every wash
- Tree sapBonds quickly in summer — remove promptly with a dedicated sap remover
- Salt airAccumulates near the coast — rinse more often if you live or park near the beach
- UVIntensity here is extreme — undercover parking still helps a coated car
Rinse it off now.
Soak it with water or a quick detailer, let it soften, then lift it with a clean microfibre. Never scrub it dry.
A rough guide only. How fast droppings etch depends on the bird, the heat and the coating, which is why the rule is simple: hours, not days.
Keeping your coating performing year after year.
An annual check-in is a fraction of the cost of a full recoat.
Even with perfect maintenance, ceramic coatings benefit from a periodic inspection and top-up treatment. Over time, the hydrophobic properties can diminish slightly; a maintenance detail and coating top-up restores performance and extends the overall life of the coating.
We recommend an annual check-in. We'll assess the coating condition, decontaminate the paint and apply a maintenance treatment to keep everything performing as it should.
Gtechniq guarantees are also subject to product registration, correct maintenance and applicable inspection requirements, so regular check-ins help keep that paperwork in order too.

Ceramic coating maintenance FAQs.
Do I still need to wash a ceramic coated car?
Yes. A ceramic coating makes washing easier, reduces how often you need to do it and protects the paint during and between washes, but it doesn't make dirt disappear.
Can I take a ceramic coated car through an automatic car wash?
It's best to avoid them entirely. A single run through an automatic car wash with rotating brushes can introduce dozens of fine scratches into a coated surface, which is immediately visible on a dark car in sunlight.
What shampoo should I use on a ceramic coating?
Use a dedicated pH neutral car shampoo. Alkaline or acidic shampoos, dish soap and household cleaners will break down the coating over time.
How quickly should I remove bird droppings from a coated car?
Within hours, not days. Bird and bat droppings etch faster in hot weather, so soften them with water or a quick detailer and lift them off with a clean microfibre as soon as you can.
How often should a ceramic coating be inspected?
We recommend an annual check-in. We assess the coating condition, decontaminate the paint and apply a maintenance treatment to keep it performing, which costs a fraction of a full recoat.
