The first 7 days
This is the cure window. Your ceramic coating is still chemically bonding to the clear coat. Anything that physically disturbs the surface during this period weakens or breaks that bond.
- Don't wash. Not even a rinse. Water during cure can leave permanent water spots in the coating itself.
- Don't cover. Car covers trap moisture against the curing surface — exactly the wrong condition.
- Don't park under sap trees. Sap that lands during cure is very hard to remove without polishing (which removes coating).
- Avoid driving in heavy rain if possible. Light rain is fine — heavy rain plus road grime is the worst combination during cure.
- Don't touch the paint. Even running a finger over a panel can disturb the molecular bond.
After 7 days, the coating is fully cured. You can wash normally — following the rules below.
The seven aftercare rules
Hand-wash only. No drive-thrus. Ever.
Drive-thru washes have rotating brushes that drag dirt across paint at high speed. They're abrasive enough to micro-mar a ceramic coating in 12-18 months. The single biggest cause of "my ceramic stopped working" we see is people who forgot they were now coated and drove through a wash.
pH-neutral soap only.
High-pH degreasers strip ceramic. Acid-based wheel cleaners strip ceramic. Use a soap labelled "pH-neutral" or "ceramic-safe". We supply one in the aftercare kit — but any quality ceramic-safe shampoo (Gyeon Bathe, GTECHNIQ Polish & Coat, CarPro Reset) works.
Two-bucket method. Microfibre mitt.
One bucket of soap, one of clean rinse water. Mitt goes back into rinse before reloading soap. Stops dirt from being dragged back across paint. Always use a microfibre wash mitt — never sponges (they hold dirt against paint), never brushes.
Wash top-down. Work in sections.
Roof first, then upper panels, doors, lower panels, wheels last (wheels are dirtiest). Work in horizontal lines, not circles — circular motions create visible swirl patterns over time. Rinse each section before moving on.
Dry with clean microfibre. Always.
Letting a coated car air-dry leads to water spots — minerals in the water deposit on the surface as it evaporates. Use a clean microfibre drying towel within 2-3 minutes of rinsing. Drying aids (quick detail sprays) help during this step.
Rinse bird droppings within 5 hours.
Bird droppings are acidic. In hot Australian sun they start etching even ceramic-coated paint within 5 hours, and become permanent stains by 12 hours. If you can't fully wash, at least rinse the spot with clean water and dab dry. Same applies to tree sap and bug splatter.
No wax, no polish, no compound.
Wax sits on top of ceramic and breaks the hydrophobic effect — wash it off. Polish and compound are abrasive — they remove the coating instantly. If your ceramic-coated car needs scratch removal, take it back to the installer; never use over-the-counter polish on coated paint.
What's safe to use
- pH-neutral car wash soap (any ceramic-safe brand)
- Ceramic detail spray / topper (Gyeon Cure, GTECHNIQ C2v3) every 3-6 months to refresh hydrophobic effect
- Quick detailer for in-between washes
- Iron remover 1-2 times a year for bonded iron particles (acid-free type only)
- pH-neutral wheel cleaner (most wheel cleaners are acid-based — read the label)
- Microfibre cloths dedicated to your car only (wash them separately, no fabric softener)
What voids the warranty
- Using a drive-thru / automated car wash (single biggest cause)
- Polishing or compounding the coated paint
- Using high-pH or acidic chemicals not labelled coating-safe
- Letting bird droppings sit for 24+ hours
- Driving on salted winter roads without rinsing afterwards
- Applying wax or sealant over the coating
- Not following the 7-day cure rule
Most manufacturer warranties also require a 6-monthly or annual inspection at the original installer to validate the coating is being maintained. At Harford Auto Studio, this inspection is included free with our Signature and Crown packages, and complimentary for Harford Care members.
The maintenance wash schedule
- Every 2 weeks — basic two-bucket wash (or sooner if visibly dirty)
- Every 3 months — full wash + detail spray topper application
- Every 6 months — professional maintenance wash + coating inspection (we include this with Signature and Crown packages)
- Every 12 months — annual coating health check and warranty validation
If you're a Harford Care member, the maintenance schedule above is built into your membership — no extra cost, just call to book.
Common situations
You drove through pouring rain on a road trip
Get to a hand-wash place or a hose at home within 24-48 hours. Rinse the car thoroughly with water (no soap if you don't have ceramic-safe), dry with a microfibre. The dirt itself isn't an emergency — letting it bake on for weeks is.
A bird absolutely nailed your bonnet
Water bottle + clean microfibre kit (keep one in the car). Wet the spot, gently lift the dropping with the cloth, rinse, dab dry. Don't scrub. Don't let it sit until you get home if home is 4 hours away.
You got a stone chip
The ceramic doesn't protect against stone chips (that's PPF's job). Take a photo and bring the car back to us — we can spot-correct the chip and re-seal the area. Otherwise the bare paint underneath will start to rust.
You washed it at a drive-thru by accident
One drive-thru isn't game-over, but it'll have done some micro-marring. Skip drive-thrus from now on. If you notice the water beading reduce, come in for a check — sometimes a single drive-thru is enough to start coating breakdown.
